Millions of Americans now exercise their Constitutional right to “keep and bear arms”, specifically to carry a pistol for personal protection and home defense. In response to the rapid growth of the CCW (Concealed Carry Weapon) market, numerous gun-makers have introduced compact handguns specifically designed for concealed carry. These “Carry Guns” tend to be smaller, lighter, with smoother, rounded edges on slide and frame. Today, many modern carry guns are also “Optics Ready”, meaning they have slides that can accept smaller red dot sights. And some companies are now selling handguns with the optics pre-installed.
For today’s Saturday video showcase, we feature six videos covering a wide range of popular semi-automatic carry guns. You’ll see offerings from Beretta, Glock, HK, Kahr, Kimber, Ruger, Smith & Wesson, Taurus, Walther and more. In addition, we’ve included a video that covers the pros and cons of installing optics on carry pistols. Finally, as a bonus, we’ve included a video that highlights five handguns that you may want to avoid, as they have not lived up to expectations.
Top Ten Best Carry Pistols for the Money
Here the Honest Outlaw Channel reviews ten semi-auto pistols. The host states these are the “10 best pistols for the money,” adding that “these handguns are reliable, accurate, durable, light weight, and cost less than most alternatives.” This video was released in December 2022, so it covers the latest generation of modern carry pistols.
Five Favorite Carry Pistols — Colion Noir’s Top Handguns
Colion Noir is a very popular gun reviewer and Second Amendment advocate. In this video, which has over 1.1 million views, Colion covers the five guns he personally carries. Why five? Colion states: “When it comes to my concealed carry guns, I practice tactical polyamory. Essentially, I don’t just carry one gun. I have a rotation of guns I carry based on what I’m wearing that day, where I’m going, and what I’m doing. I put a lot of thought into my carry rotation, which changes based on my needs. Sometimes a gun that’s better at handling the job comes out, and I’ll carry it once I’m comfortable with its reliability. That said, there are five guns I consistently carry[.]”
Five Top Choices among CCW & EDC (Everyday Carry) Handguns
The host notes: “We are going over the five best CCW firearms that I reviewed this year and ranking them from 1 to 5. We are going to save the best for the last. Some of the criteria for ranking these firearms isn’t only based on performance. We are ranking based on performance, price, reliability, and comfort.”
Ten Modern Micro-Pistols for Concealed Carry
The reviewer states: “It’s 2023 and the world of firearms keeps evolving. One of the hottest trends in the firearms industry right now is micro pistols — small, compact handguns that are perfect for concealed carry or as backup guns. If you’re looking for the best micro pistols in 2023, you’ve come to the right place. This video reviews the latest and greatest micro pistols on the market, discussing their features, performance, and why they’re making waves in the gun community.”
Kimber’s R7 Mako pistol won a coveted Golden Bullseye Award from NRA’s Shooting Illustrated magazine, taking the trophy for the magazine’s “2022 Handgun of the Year” category. The R7 Mako is very compact, with good ergonomics, yet it offers 12-rd (11+1) capacity (and 13+1 with extended magazine). The R7 Mako showed outstanding accuracy when tested indoors (see video at 15:25 time-mark).
The R7 Mako is offered Optics Ready for $599.00 MSRP or with Crimson Trace Red Dot Optic installed for $799.00 MSRP. SEE Shooting Illustrated Review.
New Heckler & Koch CC9 Double-Stack Micro-Compact
Heckler & Koch (HK) has released its new CC9 micro-compact, striker-fired 9x19mm pistol. With great accuracy, ergonomics, and reliability, the HK CC9 should be a top choice among micro-compact pistols. Designed and produced in the USA, this is the smallest double-stack carry pistol HK has ever built. The CC9 features a modular grip with swappable backstraps. With a “Safe Take Down Feature” for disassembly, there is no need to pull the trigger during field-striping, making the CC9 safer than a Glock. The slide is optics-ready and there is a short Picatinny rail on the front of the polymer frame for mounting accessories. The micro-compact CC9 is 6.03″ long and 0.99″ wide. The barrel is 3.32″ long and the CC9 weighs 18.4 ounces without magazine. MSRP is currently $699.00.
Optics on Carry Pistols — Factors to Consider
Red Dot sights are becoming more popular than ever. Many pistols today are “Optics Ready”, and some handguns can now be purchased with optics already installed. There are both strengths and weaknesses having optics on CCW handguns. In this video, Massad Ayoob outlines the pros and cons of Red Dots on carry pistols. Along with covering the factors to consider, Ayoob provides advice on red dot zeroing, defoggers, and more.
BONUS: Five Handguns to Avoid
When shopping for a handgun, it’s helpful to know which models to avoid, because of poor reliability or other shortcomings. This Honest Outlaw video reveals five handguns that are not the best choices for concealed carry: Smith & Wesson CSX, SCCY CPX-2, Remington RP-9, Kahr CW 380, and Taurus PT 22.
In some areas of the country (California in particular), hunters are now forbidden to use bullets that contain lead. If you need a lead-free projectile for your deer rifle, consider Nosler’s E-Tip projectile. This has plenty of penetrating power and retained energy while complying with laws requiring “unleaded” ammunition. An “expansion chamber” behind the green polymer tip helps ensure reliable expansion with 95% weight retention. The video below shows a .30 caliber, 180gr lead-free E-Tip impressively power through TWO 12-inch blocks of Ballistics Gel at 100 yards. This was fired from a .308 Winchester.
Watch 180gr eTip Penetration and Expansion in Ballistic Gelatin:
Nosler claims the E-Tip (“Expansion Tip”) bullet has advantages over other solid copper hunting bullets: “Unlike the competitor’s one-piece designs, Nosler E-Tip bullets will not blow the petals off at extreme velocities nor will the low end expansion ever be questioned, as the minimum impact velocity is set at 1800 fps for standard calibers.” One hunter, posting on Facebook, gave the E-Tip high marks: “I have had the opportunity to take a pig with a 130 gr E-Tip from my .270 and they work flawlessly. My son took two pigs with his .300 Win Mag and 165gr E-Tips and they worked flawlessly as well.”
This video illustrates the design and construction of the Nosler eTip Bullet:
This video shows the process of cut-rifled barrel-making by Krieger Barrels, one of the world’s best barrel manufacturers. Krieger cut-rifled barrels have set numerous world records and are favored by many top shooters. The video show the huge, complex machines used — bore-drilling equipment and hydraulic riflers. You can also see how barrels are contoured, polished, and inspected.
For anyone interested in accurate rifles, this is absolutely a “must-watch” video. Watch blanks being cryogenically treated, then drilled and lathe-turned. Next comes the big stuff — the massive rifling machines that single-point-cut the rifling in a precise, time-consuming process. Following that you can see barrels being contoured, polished, and inspected (with air gauge and bore-scope). There is even a sequence showing chambers being cut.

“At the start of World War Two, Pratt & Whitney developed a new, ‘B’ series of hydraulically-powered rifling machines, which were in fact two machines on the same bed. They weighed in at three tons and required the concrete floors now generally seen in workshops by this time. Very few of these hydraulic machines subsequently became available on the surplus market and now it is these machines which are sought after and used by barrel makers like John Krieger and ‘Boots’ Obermeyer. In fact, there are probably less of the ‘B’ series hydraulic riflers around today than of the older ‘Sine Bar’ universal riflers.” — Geoffrey Kolbe, Border Barrels.
Have a good look at the photos below — this may be one of the most noteworthy target strings we’ve ever published. What you can see is the effect of barrel tuner position on point of impact (POI). You can clearly see that the tuner position alters the up/down POI location in a predictable fashion.
This remarkable 15-shot sequence was shot by French benchrester Pascal Fischbach using his 6 PPC fitted with a CG (Carlito Gonzales) action and a Bukys barrel tuner.
Pascal reports: “After [bullet] seating and load validation, I put the Bukys tuner on, screwing it out 10 turns. According to Carlito, the CG’s super stiff action-to-barrel fit gives a faster vibration modulus that is detrimental below 10 turns [position of the tuner].” Pascal’s procedure was to screw out the tuner 1/4 turn progressively from one shot to the next. He shot one bullet at each tuner position, with a total of 15 shots.
Left Half of Target Strip (shots with 1/4 rotation change of tuner in sequence)
Right Half of Target Strip (shots with 1/4 rotation change of tuner in sequence)
Pascal observed: “Note the point of impact displacement [from shot to shot] tracks clearly along a sinusoide (sine wave curve).” This is indeed notable and significant! This shows how the tuner’s ability to change barrel harmonics can alter the position of the muzzle as each bullet exits, resulting in a higher or lower POI. Pascal sent his results to Carlito Gonzales in Argentina for analysis.
Pascal poses this question to readers: “Guess which three positions Carlito recommends to try?”
Editor’s Note: While this target sequence clearly shows how tuner position can alter bullet point of impact, this, by itself, does not tell us which tuner position(s) are best for accuracy. That will require further multi-shot group testing, involving careful experimentation with tuner position (and powder charge weights). But for those folks who doubt that a tuner can make a difference on a short, fat barrel, just take another look at the photos. The up/down changes are undeniable, and noteworthy in the wave pattern they follow.
Shooting Set-up and Test Conditions:
Pascal did this test at an outdoor range under very good conditions: “This was shot at my home range, outdoors, with four Smiley flag. The range is a narrow cut in high woods. Wind was consistent with readable flags. I started testing the tuner from 10 turns out and on to 15. I recently… found a sweet spot very close to the rearmost position of the tuner, so the rigidity provided by this super long tenon (just short of 70mm) was not a reason to overlook the recommended Bukys tuning procedure.”
PASS or FAIL? Where does your U.S. Representative and U.S. Senator stand when it comes to supporting the Second Amendment, the firearm industry, hunting, and target shooting sports? NSSF has released its 2024 Congressional Report Card. You can view it here: CLICK HERE for Full REPORT CARD.
The Firearm Industry Trade Association (NSSF), released its 2024 Congressional Report Card, grading U.S. Representatives and U.S. Senators on key legislation relating to the firearm industry, to hunting and recreational shooting, and to the Second Amendment rights of U.S. citizens.
“This report card will be critical for voters to do their research as we head into … the November elections just six weeks from now. NSSF’s 2024 Congressional Report Card tells voters exactly where their lawmakers stand on issues including defending the firearm industry’s ability to engage in the lawful commerce of firearms and ammunition and safeguarding the Second Amendment rights of customers, as well as promoting hunting and recreational target shooting”, said Lawrence G. Keane, NSSF Senior VP and General Counsel. “This nonpartisan report card reflects the level of support of each lawmaker on firearm industry priority legislation during the 118th Congress, between 2023 and 2024. These grades indicate their public voting record as well as their sponsorship and co-sponsorship of key legislation, their work on committees, letters signed to support firearm industry issues, and their overall leadership[.]”
NSSF awarded 29 U.S. Senators and 123 U.S. Representatives the rating of “A+”. Of those, 8 Senators and 24 House Members attained the new NSSF distinction of being named to the Dean’s List. To earn this special recognition, members needed to have a 100-percent voting and co-sponsorship record.

NRA publication Shooting Sports USA (SSUSA) has thousands of articles online, all free for the reading. Many of these stories have been written by top competitors, including National and Olympic Champions. You will find SSUSA articles spotlighted every week on the NRA Competitive Shooting Facebook page. We recommend you bookmark that page as a valuable resource. Here are four notable SSUSA articles that have been featured on Facebook this month. Go to SSUSA.org to see even more current articles, with new content every day.
Here is an insightful, fairly lengthy 1850-word article about the phenomenon we call mirage. The article explains how and why mirage appears, how it can best be monitored, and how mirage can indicate both wind velocity and direction. Top competitors follow the adage “Mirage is your friend”, because mirage can often be the most important indicator of wind variables — sometimes even more important than wind flags. “The mirage is more sensitive than the flags since it has less inertia and momentum”, wrote Desmond T. Burke, in his book, Canadian Bisley Shooting, an Art and a Science.
Well worth reading, this SSUSA article talks about the properties of mirage. Here is a sample:
“Mirage — can make all the difference between a shot landing squarely in the X-ring or being victimized by an undetected downrange breeze. The true power of mirage is found in its ability to betray the subtlest of breezes downrange. Its fluid movement… can not only provide wind direction, but speed as well.
Typically, the ability to detect mirage is maximized on warm, sunny and sultry days. Expect mirage to be most pronounced in mid-morning or early afternoon, although it ignores these rules with regularity[.]
Mirage is extremely powerful at identifying winds of less than 12 mph, particularly those gentle breezes subtle enough to not even bother moving the flags.
When there is no wind, or a gentle head or tail wind, mirage will appear to be ‘bubbling’ directly up from the ground. Many call this ‘boiling’, and it is probably the easiest of all to detect.
As a general rule of thumb, when wind speed increases, overall height of the waves produced by the mirage is reduced. Large peaks and valleys in the waves mean that particular mirage is being driven by a very slight breeze. Conversely, crest size is reduced with wind speed, making it harder and harder to detect, until the mirage disappears entirely at somewhere around 12 miles per hour. In other words, the taller mirage’s waves appear, the slower the breeze.”
Authored by the late Glen Zediker, this article covers barrel break-in procedures. It is particularly useful for dealing with factory barrels. We CAUTION readers — with outstanding, hand-lapped custom barrels from top barrel-makers, you may want to do very little break-in — clean sparingly and keep barrel heat low. Do NOT use abrasives aggressively. On our Krieger and Brux barrels, we simply wet-patched every 2-3 rounds for 20 rounds and the barrels shot superbly from the start with minimal fouling. But for factory barrels, a moderate break-in process may prove beneficial.
Zediker explains: “Lesser, lower-cost barrels are going to have more pronounced … imperfections within the bore[.] These imperfections are largely tool marks resulting from the drilling and rifling processes. And if it’s a semi-automatic, like an AR-15, there might be a burr where the gas port was drilled. The goal of break-in is to knock down these imperfections, thereby smoothing the interior surface.”
As one who has experienced a cartridge case-head blow-out with a 9mm pistol, this Editor is very conscious of the risks involved and the damage a blow-out can do to the pistol, to the magazine, and (worst of all) to the shooter. Even with new brass, the possibility of a case failure is always present. And even if the case remains intact, we’ve seen primer failures that create a dangerous jet back towards the pistol shooter. That’s why shooters should always employ protective eyewear whenever they shoot.
We love our wheelguns, but there’s no doubt that forcing cone damage can occur, particularly with hot loads and if your cylinder-to-barrel gap is excessive. This article explains how to inspect your revolvers, and how to mitigate the likelihood of forcing cone damage. The article also explains how to clean your revolvers properly. This is very important to avoid build-up of lead and powder residues.
Reader Mike Etzel has come up with a simple, cost-effective way to apply moly or danzac coatings to your bullets. And you won’t need any expensive gear other than your regular vibratory tumbler and some small plastic containers.
Mike explains: “For a number of years I have been using a very convenient way of coating my projectiles with DANZAC in a tumbler. Instead of using a separate tumbler filled with DANZAC and stainless steel balls for coating applications, use small resealable plastic cake or pudding cups filled with stainless balls and DANZAC. Each cup will accommodate between 20 to 70 projectiles depending on caliber once the polishing balls and DANZAC are added. When I need to polish some cases, I insert the sealable plastic container(s) into the polishing material in the tumbler, add cases to the media, and in the process clean cases and coat the projectiles simultaneously in one tumbler. This does two operations in one session, saving on time and resources.”
While Mike uses DANZAC (Tungsten DiSulfide or WS2), you can use the same impact-tumbling-in-a-cup method to moly-coat your bullets, or to apply HBN (Hexagonal Boron Nitride).
TIPS for COATING your BULLETS, by “GS Arizona”
1. Start with Clean Bullets. This is simple enough, but some people overlook it and others overdo it. Get the bullets out of the box, wash them with warm water and dish soap and dry them. No need for harsh chemicals, after all, we’re only removing some surface dirt from shipping and maybe some left over lanolin from the forming process. Don’t handle them with bare hands once they’re clean, your skin oils will contaminate them.
2. Get Everything Hot — Real Hot. This is probably the single most important element in producing good-looking moly-coated bullets. I put the tumbler, the drum and the bullets out in the sun for at least 30 minutes before starting and then do all the tumbling in direct sunlight. On a summer day in Arizona, everything gets to the point that its uncomfortably hot to handle. If you are tumbling in the winter, you should heat the bullets in some form, a hair dryer can be useful, but they will cool off in the drum if you’re tumbling in cold temperatures. Your best bet is to plan ahead and do your coating in the summer. I coated about 3000 bullets in a couple of days recently to see me through our winter season (we’re a bit reversed from the rest of the country in terms of shooting season).
Heckler & Koch (HK) has released its new CC9 micro-compact, striker-fired 9x19mm pistol. With great accuracy, ergonomics, and reliability, the HK CC9 should be a top choice among micro-compact pistols. Designed and produced in the USA, this is the smallest double-stack carry pistol HK has ever built. The CC9 features a modular grip with swappable backstraps. With a “Safe Take Down Feature” for disassembly, there is no need to pull the trigger during field-striping, making the CC9 safer than a Glock. The slide is optics-ready and there is a short Picatinny rail on the front of the polymer frame for mounting accessories. The micro-compact CC9 is 6.03″ long and 0.99″ wide. The barrel is 3.32″ long and the CC9 weighs 18.4 ounces without magazine. MSRP is currently $699.00.
Compact and Concealable:
As the smallest double-stack pistol HK has ever produced, the CC9 should be a good choice for for concealed carry. Chambered in 9mm Luger (9x19mm), the CC9 comes equipped with both 10-round and 12-round magazines for flexibility in concealment. The CC9’s slim and relatively lightweight design (18.4 ounces without mag) features ambidextrous controls including slide-stop and magazine release. The edges of the slide are rounded for easier carry and smooth holstering.
Military-Grade Testing:
The CC9 is held to the same standards as full-size duty pistols and tested to NATO Army Armaments Group AC/225 standards. The CC9 was subjected to a battery of tests including extreme temperatures, dust, sand, mud and being dropped to simulate real world conditions. The CC9 had over 750 thousand rounds fired during development and testing. The CC9 is built to perform flawlessly in the most demanding conditions.
HK claims the CC9 delivers exceptional accuracy and control. The chassis system is rated for full +P 9mm ammo. The CC9 features a modular grip with interchangeable backstraps to fit various hand sizes. Boasting good ergonomics, the CC9 offers a full 4-finger grip and the same length of pull as the full-sized VP9 pistol. The trigger is smooth and consistent (better than a Glock in our opinion) and recoil is very manageable. Watch the embedded videos to see the new CC9 in action. The optics-ready CC9 features a tritium front sight, and a blacked-out, serrated rear sight for quick target acquisition.
Safety is integral to the CC9’s design. The pistol is equipped with multiple safety features, including a trigger safety, passive firing pin safety, Out-of-Battery safety and Safe Take Down Feature. The magazine must also be removed before the take-down lever can be rotated. Additionally, the CC9 includes a visual/tactile loaded chamber indicator built-in to the extractor.
Designed for modern concealed carry, the CC9 is compatible with a wide range of accessories, including lights and lasers, with its integrated Picatinny-style accessory rail. Optics can be mounted directly to the slide featuring a RMSc / 407k footprint compatible with most modern micro-dots.
What would you do if you had a LIVE Round stuck in a chamber? Well, don’t hammer a wood dowel in the barrel, that’s for sure. Here is a tale of stupidity that could have injured the rifle owner. This account appeared on the Facebook Page of Brock & Norris Custom Rifles, a gunsmith shop in the United Kingdom.
Live, Loaded Round Stuck in Chamber — What NOT to Do!
Commentary by gunsmith Mike Norris
Here is a cautionary tale. A client came into the workshop with a problem which could have had very serious [even deadly] consequences. And it is not the first time we have seen this. Firing neck-sized-only ammunition, the client attempted to load a round which then jammed solid in the chamber. The bolt would not close and the round was unable to be extracted.
The problem was compounded by various attempts to push the loaded round from the chamber with cleaning rods and the assistance of a hammer (I kid you not!). All of which damaged the bore and the crown, culminating in a wooden dowel being hammered into the barrel which subsequently broke off in the bore. The end result was a barrel that was totally wrecked.
One Facebook friend posted: “Fortunate avoidance of a ‘Darwin Award’. I can hear it: ‘Go on hammer the bolt, she’ll go!’. We’re missing a ‘face palm’ emoji here.”
The Problem Started with a Neck-Sized Case
The moral of this story is DO NOT NECK SIZE cases. Mike advises: “Full-length size cases correctly. You only move the shoulder back 1 to 1.5 thousandths and the case will feed and extract EVERY TIME. Yes you will have to trim cases occasionally but it is one hell of a site cheaper and safer than jamming a live round in the barrel and wrecking the barrel trying to remove it. Not to mention the risk to life and limb!”
What Should Have Been Done in this Situation?
Mike was asked the best method for removing a stuck round. He stated: “The Grease Gun Method on a threaded barrel works*. However, in this case, this was not remotely possible due to 20 inches of wooden dowel being broken off in the bore as well. The live round (yes it was live!) was attempted to be removed by hammering on a brass cleaning rod (an actual hammer was used) to try to dislodge it. That brass rod broke, so then a wooden dowel was employed, and THAT broke as well.”
Mike cautions that, when a live, loaded round is involved you must be very careful: “Do not be taking chances with your own safety or others around you. When it is safe to do so, get the rifle to a professional. By the way he WILL [chide you] for being daft in the first place and then bringing the problem into his premises. Expect to be charged for the expertise to remove said obstruction, In the past I even had a client send me a loading die with a live .338 Lapua round in it through the Post no less!”
* This YouTube Video shows the successful removal of a jammed FIRED (not live) case from an AR15 barrel. You can see the fired case eject at 15:35 time-mark, after the primer pops out first. But note, this was NOT a live, loaded round. Extreme caution must be excercised with live rounds.
AR-15 Cartridge line-up image from 80% Arms, used with permission. This selection omits our favorite alternative — the 20 Practical (.223 Rem necked down to .204 Caliber).
Instead of using the standard .223 Remington or 5.56x45mm NATO round, you have many options for an AR-15, as shown above. This photo is from Complete Guide to Alternative AR-15 Rounds in the 80% Arms Blog. Some of the most notable alternative chamberings for AR-15s are:
20 Practical — Simply the .223 Rem necked down to .204 caliber. Requires new barrel. Same bolt, same magazines. Best Bang for the Buck. 6mm ARC — The 6mm ARC (from Hornady), is a SAAMI cartridge optimized for AR-platform rifles. The 6mm ARC is basically a 6.5 Grendel necked down to 6mm, with the shoulder moved back around .030″. 6.5 Grendel — Moderately expensive, 6.5 Grendel requires a new barrel, bolt, and magazines. Most use the 6.5 Grendel for competitive shooting and/or hunting. .300 Blackout — Moderately expensive, the .300 Blackout requires a barrel change. This is used for home defense, and hunting. WARNING — with some bullets this round can be chambered in a .223 Rem barrel, with disastrous consequences. .50 Beowulf — The most expensive alternative AR-15 cartridge, this requires new barrel and bolt. The .50 Beowulf was created for game hunting, but most hunters use something more practical.
Of these five options, our top choice is the 20 Practical, followed by the 6.5 Grendel. Check out our featured 20 Practical AR Rifle Report. This 20 Practical cartridge is highly effective on small varmints, and has shown outstanding accuracy in AR-platform rifles crafted by Robert Whitley.
20 Practical — High-Velocity, Affordable Alternative
The 20 Practical is simply a .223 Remington necked down to .204 caliber. This efficient little cartridge can launch 32-grainers at over 4200 fps, with impressive results on P-Dogs. This makes the 20 Practical a great choice for an AR-based varmint rifle.
20 Practical Ultimate Varminter
Many years back, as a “proof-of-concept”, AccurateShooter.com created a 20 Practical AR15 Ultimate Varminter with a custom 20-caliber upper from Robert Whitley of AR-X Enterprises, LLC. That project rifle was ultra-accurate — every 5-shot group out of the gun was less than the size of a dime. The 20 Practical cartridge is simply the .223 Rem necked down to 20 caliber — you can use standard .223 brass and load with standard .223 Rem dies. Just swap in a smaller expander and use smaller neck bushings.
20 Practical in AR15 Demonstration Video
6mm ARC — Popular New SAAMI Cartridge Promoted by Hornady
The 6mm ARC is basically a 6.5 Grendel necked down to 6mm, with the shoulder moved back around .030″. That pushed-back shoulder does reduce case capacity (and velocity), but we assume Hornady did that to create a shorter, proprietary chamber so people could not simply neck-down Lapua 6.5 Grendel brass, as has been done for years with Robert Whitley’s outstanding 6mm AR wildcat.
What Is the 6mm ARC Cartridge? The 6mm ARC cartridge is a modern SAAMI-spec cartridge based on the 6.5 Grendel case necked down for 6mm bullets, with the shoulder moved back 0.030. Yes it is designed to run in AR15-platform rifles. You’ll need a new barrel, bolt, and mags. If you already have an AR chambered in 6.5 Grendel, the ONLY thing you need to change is the barrel. Everything else — bolt, magazines, gas system – is compatible with 6mm ARC.
▶ Official SAAMI Cartridge (not wildcat)
▶ Fits standard AR15-platform rifles
▶ Fits Short/Mini action bolt rifles
▶ Efficient short, fat case design
▶ 30-degree case shoulder
What Do I Need To Shoot the 6mm ARC?
Faxon and Ballistic Advantage are already producing barrels, with more manufacturers sure to follow. All the other required components are already on the market for 6.5 Grendel rifles. Aero Precision already offers complete 6mm ARC uppers.
If you’re converting a standard 5.56×45 mm (.223 Rem) AR15 upper to shoot 6mm ARC, you’ll need a 6mm barrel, a Type II 6.5 Grendel bolt carrier group, and new magazines. Some folks have suggested standard AR mags will work, but trust us, you want magazines designed for 6.5 Grendel.
While 6-6.5 Grendel shooters are known to run stout pressures, the 6mm ARC cartridge has a relatively moderate Maximum Average Pressure (MAP) rating of 52,000 psi according to the official SAAMI specifications. For a variety of reasons, is wise to keep pressures in a semi-auto rifle moderate. Don’t chase the velocities you might get in a bolt-action gun.
The 6.5 Grendel — Accurate, Plus Good for Hunters
The 6.5 Grendel round is one of the most accurate cartridges for the AR-15 platform. The 6.5 Grendel round offers a larger-diameter, .264-caliber (6.5mm) bullet running at good velocities. This provides ample energy for smaller game and deer. The 6.5 Grendel is often used for hunting deer up to 300 yards.
History of the 6.5 Grendel Cartridge
The 6.5 Grendel originated as a 6mm PPC necked up to 6.5 mm. After Alexander Arms relinquished the “6.5 Grendel” Trademark, the 6.5 Grendel was standardized as an official SAAMI cartridge. It has become popular with target shooters and hunters alike because it is accurate, efficient, and offers modest recoil. Good for small to medium game, the 6.5 Grendel is becoming a popular chambering in lightweight hunting rifles, such as the Howa 1500 Youth Model.
The .300 Blackout — Risky Business
The .300 Blackout appeals to folks who want a .30-caliber defense round. This can be loaded at various velocities. Loaded at subsonic speeds and shot with a suppressor, the .300 BLK offers very low sound levels. Unfortunately, that .300 Blackout cartridge can fit in a .223 Rem chamber. Shooting a .308-caliber bullet in .223 bore is a recipe for disaster.
The .300 AAC Blackout aka “300 BLK”, is a compact 30-caliber cartridge designed to work in AR-15 rifles. It has a shorter cartridge case to accommodate the bigger 30-caliber bullet while still fitting in a standard AR-15 magazine. Unfortunately, that’s the danger. A careless shooter can toss a .300 Blackout cartridge in with .223 Rem rounds without noting. And because the case-head size is the same as the .223 Rem (5.56×45) the rifle’s bolt assembly will happily chamber and fire the .300 BLK round. Problem is, that forces a .308 diameter bullet down an undersized .223-caliber bore. Not good!
This images were provided by Tactical Rifle Shooters on Facebook. The message was clear: “Don’t try to run 300 Blackout in your .223/5.56mm. It won’t end well. The problem is identical rifles and identical magazines but different calibers.”

For those who MUST have a .300 Blackout, here are some things you can do:
1. Use different colored magazines for .300 Blackout vs. .223 Remington.
2. Mark .223 Rem upper handguards with the caliber in bright paint.
2. Fit all your uppers with caliber-labeled ejection port covers.
4. Mark all .300 BLK Rounds with heavy black marker.
Have a good look at the photos below — this may be one of the most noteworthy target strings we’ve ever published. What you can see is the effect of barrel tuner position on point of impact (POI). You can clearly see that the tuner position alters the up/down POI location in a predictable fashion. 
Reader Mike Etzel has come up with a simple, cost-effective way to apply moly or danzac coatings to your bullets. And you won’t need any expensive gear other than your regular vibratory tumbler and some small plastic containers.
2. Get Everything Hot — Real Hot. This is probably the single most important element in producing good-looking moly-coated bullets. I put the tumbler, the drum and the bullets out in the sun for at least 30 minutes before starting and then do all the tumbling in direct sunlight. On a summer day in Arizona, everything gets to the point that its uncomfortably hot to handle. If you are tumbling in the winter, you should heat the bullets in some form, a hair dryer can be useful, but they will cool off in the drum if you’re tumbling in cold temperatures. Your best bet is to plan ahead and do your coating in the summer. I coated about 3000 bullets in a couple of days recently to see me through our winter season (we’re a bit reversed from the rest of the country in terms of shooting season).
