Many of our readers have never had a chance to shoot much past 600 yards. How far away does a 1000-yard+ target really seem to the naked eye? Well this short video answers that question. Gorilla Ammo, the video’s producers, used a camera-carrying aerial drone to fly downrange from the firing line all the way out to 1122 yards (and back again). Watch the drone footage at 0:00-0:07 and especially 0:48-1:03. The “bird’s-eye view” really gives you a sense of the distance. The “fly-back” at 0:48-1:03 time-mark is what makes this video worth watching.
The video features prone shooting at steel targets placed at 750 and 1122 yards. We do apologize for the lame, “oh so serious” voice-over which attempts to make this rather ordinary range session seem like some kind of life-changing experience. (Frankly, you may just want to turn the sound off — it’s that annoying.) It’s really not that big a deal to hit steel at 750 yards with a quality AR-15, chambered in .223 Rem, shooting Sierra 77 grain MatchKings.
Hitting Steel at 1122 Yards with 2540 FPS Ammo Can Be Challenging
The 1122-yard hits are a bit more impressive. Gorilla Ammo lists a relatively sedate 2540 fps Muzzle Velocity for its .223 Rem 77gr SMK ammunition. According to JBM Ballistics, at 1125 yards, that 2540 fps load has 68.3 MOA of drop from a 100-yard zero (firing at sea level and 80° F ambient). Moreover the bullet goes trans-sonic around 750 yards (losing stability) and is traveling just 933 fps at impact. And the wind’s the killer — at 1125 yards, with this bullet/load, a mere 2 mph, full-value wind change can move the Point of Impact over three feet!

Let’s face it, AR-platform rifles run dirty, at least compared to typical bolt-action rifles. The AR-15 works by piping gas from the barrel back into the bolt carrier, causing the bolt to unlock and the carrier to move the bolt backward. The “exhaust gas” from the barrel contains soot and carbon. The carbon will form hard deposits on the bolt. In addition, the carbon can combine with lube on the bolt carrier to make a nasty, paste-like sludge. This can be particularly problematic when the black paste pollutes the ejector and extractor recess.
This Editor has inspected dozens of ARs over the years. Other than mag-related malfunctions, the most common cause of AR cycling problems I found was oily gunk in the extractor and ejector areas. Many AR owners overlook these critical areas. Look at an AR that hasn’t been cleaned properly and you’ll probably find black gunk (and small brass shavings) in the ejector and extractor recesses.
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here are three videos that explain how to properly disassemble and clean AR-platform rifles. And then they cover the essential lubrication ARs need to run reliably.

General AR-15 Maintenance and Lubrication
There are various schools of thought on AR lubrication. Some guys like to run “wet” with lots of CLP, while others choose to focus lubrication on the key spots that receive the most friction and wear, such as the contact point for the bolt carrier. We do advice check the ejector recess and extractor spring recess frequently as gunk can get in there, causing malfunctions. Here is a good video from Pew Pew Tactical — a 7-minute guide to cleaning and lubricating AR-platform rifles. This shows important details for both the upper and the lower.
How to Clean Your AR-15 Bolt Carrier Assembly
This video offers very specific advice on the bolt carrier group, which receives the dirty gas directly from the barrel. Be sure to check the extractor and ejector recesses. That’s where old lube, brass shavings, and carbon accumulate. Follow the directions in this video for lubrication, and don’t over-lubricate the bolt carrier — that will only capture more carbon.

AR-platform rifles run dirty — very dirty. The gas system blows carbon and powder residues back into the action and into the bolt carrier group. That’s why you need to clean your ARs regularly, and you have to pay special attention to the nooks and crannies in the bolt and bolt carrer. The majority of AR failures we’ve witnessed have been from a combination of lube, carbon, and tiny brass shavings that collected in the ejector recess and the extractor spring recess. After that, plain carbon build-up on the bolt can be a gun-stopper too. And you need to keep the barrel extension clean too.
If you’re new to the (dirty) world of ARs, here are two helpful videos from the folks who make Froglube. That line of cleaners/lubes is pretty good stuff, though not our first choice for all AR lubrication and cleaning chores. But these videos do provide many helpful tips. They show the disassembly process and highlight the problem areas to which you must pay special attention.

One Shooters’ Forum member asked: “What makes an AR accurate? What parts on an AR can really affect accuracy — such as free-floating handguards, barrels, bolts, bolt carriers?” He wanted an honest, well-informed answer, not just sales pitches. Robert Whitley posted a very detailed answer to this question, based on his experience building/testing scores of AR-platform rifles. Robert runs AR-X Enterprises, which produces match-grade uppers for High Power competitors, tactical shooters, and varminters.
Building an Accurate AR — What is Most Important
by Robert Whitley
There are a lot of things that can be done to an AR to enhance consistent accuracy, and I use the words “consistent accuracy” because consistency is a part of it (i.e. plenty of guns will give a couple great 5-shot groups, but won’t do a very good 10- or 20-shot groups, and some guns will shoot great one day and not so good on others).
Here are 14 key things we think are important to accuracy.
1. Great Barrel: You’ll want a premium match-grade barrel, well-machined with a good crown and a match-type chambering, true to the bore and well cut. The extension threads must also be cut true to the bore, with everything true and in proper alignment.
2. Rigid Upper: A rigid, heavy-walled upper receiver aids accuracy. The typical AR upper receiver was made for a lightweight carry rifle and they stripped all the metal they could off it to make it light to carry (which is advantageous for the military). The net result are upper receivers that are so thin you can flex them with your bare hands. These flexible uppers are “strong enough” for general use, but they are not ideal for accuracy. Accuracy improves with a more rigid upper receiver.
3. True Receiver Face: We’ve found that truing the receiver face is valuable. Some may argue this point but it is always best to keep everything related to the barrel and the bore in complete alignment with the bore (i.e. barrel extension, bolt, upper receiver, carrier, etc.).
4. Barrel Extension: You should Loctite or glue the barrel extension into the upper receiver. This holds it in place all the way front to back in the upper receiver. Otherwise if there is any play (and there typically is) it just hangs on the face of the upper receiver completely dependent on the face of the upper receiver as the sole source of support for the barrel as opposed to being made more an integral part of the upper receiver by being glued-in.
5. Gas Block: You want a gas block that does not impose pointed stress on the barrel. Clamp-on types that grab all the way around the barrel are excellent. The blocks that are pinned on with tapered pins that wedge against the barrel or the slip on type of block with set screws that push up from underneath (or directly on the barrel) can deform the bore inside of the barrel and can wreck the accuracy of an otherwise great barrel.
6. Free-Float Handguard: A rigid, free-float handguard (and I emphasize the word rigid) really makes a difference. There are many types of free-float handguards and a free-float handguard is, in and of itself, a huge improvement over a non-free-float set up, but best is a rigid set-up. Some of the ones on the market are small diameter, thin and/or flexible and if you are shooting off any type of rest, bipod, front bag, etc., a rigid fore-end is best since ARs want to jump, bounce and twist when you let a shot go, as the carrier starts to begin its cycle before the bullet exits the bore.
7. Barrel Contour: You want some meat on the barrel. Between the upper receiver and the gas block don’t go real thin with a barrel (we like 1″ diameter if it’s workable weight-wise). When you touch off a round and the bullet passes the gas port, the gas system immediately starts pressuring up with a gas impulse that provides vibrations and stress on the barrel, especially between the gas block back to the receiver. A heavier barrel here dampens that. Staying a little heavier with barrel contour through the gas block area and out to the muzzle is good for the same reasons. ARs have a lot going on when you touch off a round and the gas system pressures up and the carrier starts moving (all before the bullet exits the bore) so the more things are made heavier and rigid to counteract that the better — within reason (I’m not advocating a 12-lb barrel).
8. Gas Tube Routing Clearance: You want a gas tube that runs freely through the barrel nut, through the front of the upper receiver, and through the gas key in the carrier. Ensure the gas tube is not impinged by any of them, so that it does not load the carrier in a stressed orientation. You don’t want the gas tube bound up so that when the gas tube pressures up it immediately wants to transmit more force and impulse to the barrel than would normally occur. We sometimes spend a lot of time moving the gas block with gas tube on and off new build uppers and tweaking gas tubes to get proper clearance and alignment. Most gas tubes do need a little “tweaking” to get them right — factory tubes may work OK but they typically do not function optimally without hand-fitting.
9. Gas Port Tuning: You want to avoid over-porting the gas port. Being over-gassed makes the gas system pressure up earlier and more aggressively. This causes more impulse, and increases forces and vibration affecting the top end and the barrel. Tune the gas port to give the amount of pressure needed to function properly and adequately but no more.
10. Front/Back Bolt Play: If accuracy is the game, don’t leave a lot of front/back bolt play (keep it .003″ but no more than .005″). We’ve seen factory rifles run .012″ to .015″ play, which is OK if you need to leave room for dirt and grime in a military application. However, that amount of play is not ideal for a high-accuracy AR build. A lot of front/back bolt play allows rounds to be hammered into the chamber and actually re-formed in a non-consistent way, as they are loaded into the chamber.
11. Component Quality: Use good parts from a reputable source and be wary of “gun show specials”. All parts are NOT the same. Some are good, some are not so good, and some aftermarket parts are simply bad. Don’t be afraid to use mil-spec-type carriers; by and large they are excellent for an accuracy build. Also, remember that just because a carrier says “National Match” or something else on it does not necessarily mean it’s any better. Be wary of chrome-plated parts as the chrome plating can change the parts dimensionally and can also make it hard to do hand-fitting for fit and function.
12. Upper to Lower Fit: A good upper/lower fit is helpful. For quick and dirty fit enhancement, an Accu-Wedge in the rear helps a lot. The ultimate solution is to bed the upper to a specific lower so that the upper and lower, when together, are more like one integral unit. For the upper receivers we produce, we try to get the specs as close as we can, but still fit the various lowers in the market place.
13. Muzzle Attachments: Don’t screw up the muzzle (literally). Leave as much metal on the barrel at the muzzle as you can. People like to thread the muzzle for a flash hider, suppressor, muzzle brake, or some other attachment, but if you really want accuracy, leave as much metal as you can there. And, if you have something that screws on, set it up so that it can be put on and have it stay there without putting a lot of torque and stress on it right where the bullet exits the bore. If you are going to thread the end of the barrel, make it concentric with the bore and make sure what you screw on there is as well. For all muzzle attachments, also ensure that the holes through which the bullet passes through are dead true to the bore. Many aftermarket screw-on things are not so good that way. Anything that vents gas should vent symmetrically (i.e. if it vents left, it should vent equally right, and likewise, if it vents up, it should vent down equally). Uneven venting of gas can wreck accuracy.
14. Quality Ammunition: Ammo is a whole story by itself, but loads that are too hot typically shoot poorly in an AR-15. If you want accuracy out of an AR-15, avoid overly hot loads. Shown below are test groups shot with four (4) different uppers, all with moderate loads. These four uppers all pretty much had the same features and things done to them as explained in this article, and they all shot great.
For decades, Shooting USA has been a leading video resource for the shooting sports and hunting. This popular cable TV show covers shooting matches, and provides expert information on precision shooting, gun maintenance, optics, and defensive firearms use. Here are five interesting videos all worth watching. Learn about wind-reading, gun maintenance, and optics.
1. Reading the Wind — SGT Sherri Jo Gallagher of USAMU
Sergeant Sherri Jo Gallagher formerly of the U.S. Army Marksmanship Unit (USAMU) shows us how to read the wind in given conditions, and how to apply your wind assessment when aiming down-range. During her time with the USAMU, Sherri won the National High Power Championship, and was the first woman in history to earn the U.S. Army “Soldier of the Year” honors. Sherri comes from a legendary family of shooters — she was raised by Ace Marksman Mid Tompkins and mother Nancy Tompkins, the first female to win the NRA National High Power Championship.
2. Field-Stripping and Cleaning AR-Platform Rifles
Let’s face it — Black Rifles run dirty. On AR-platform rifles, the gas system blows carbon and powder residues back into the action and bolt carrier group. Accordingly, you need to clean ARs early and often, and you should fully disassemble the bolt carrier to access parts and recesses which accumulate greasy lube and hard carbon. This helpful video shows how to field-strip and clean AR-platform rifles. If you own an AR, this is definitely worth viewing. With over 2.7 million views, this is the second most-watched video on Shooting USA’s YouTube Channel.
2. MOA Defined — Jim Scoutten Explains Minute of Angle
Minute of Angle (MOA) — this is the most common measurement of group size, and hence rifle accuracy. You hear about shooters hoping to shoot 1 MOA or “half-MOA”, but many folks could not give you a precise definition. In fact MOA is an angular measurement that equates to one-sixtieth of one degree of Arc. In this video, host John Scoutten defines MOA. He then demonstrates how MOA translates to accuracy on target. He demonstrates one-half-MOA accuracy with a Les Baer Custom rifle. This company offers a three-shot, half-MOA guarantee for its rifles.
4. How to Adjust for Parallax
Most precision rifle scopes have parallax adjustment, typically a knob on the left side of the scope. but what exactly is “Parallax” and why do you need to adjust optics to ensure the parallax setting is optimal? In this Shooting USA video, John Paul of JP Rifles defines parallax and explains why you need to set parallax correctly for the distance to your target. The video then shows how to adjust parallax correctly, a process which should start with the scope’s ocular focus.
5. How to Mount a Riflescope
When mounting a scope you want to use quality rings, and ensure that the scope is leveled properly. In addition, you need to adjust the fore/aft position of the scope so that eye relief is correct. Ideal scope position may be different when shooting from the bench vs. shooting prone. In this Shooting USA video John Paul of JP Rifles reviews scope mounting basics.

Do you use an AR15 for service rifle, 3-Gun, or tactical competitions? Then you should consider dry-fire training. Many top competitors spend an hour (or more) dry-firing for every minute they shoot live cartridges in competition. The allows effective training without spending a fortune on live ammunition (which can run $1.00 per round or more).
There is a handy new system that resets the trigger on AR-platform rifles — the Mantis Blackbeard (see videos below). This permits you to make multiple successive shots without having to alter your grip and manually recycle the charging handle. This two-part system employs a replacement bolt carrier/bolt and replacement magazine. With these two components installed, your AR can automatically reset the trigger instantly after you pull the trigger. It works, it’s effective, and it’s affordable at $219.00 MSRP.
The Blackbeard system is used by the U.S. Marine Corps and U.S. Army (including Special Forces), so you know it works. During training the Mantis Blackbeard allows unlimited, repetitive Dry Firing without resetting the charging handle. That eliminates a tedious task that requires altering your hold on the rifle.

This Editor has inspected dozens of ARs over the years. Other than mag-related malfunctions, the most common cause of AR cycling problems I found was oily gunk in the extractor and ejector areas. Many AR owners overlook these critical areas. Look at an AR that hasn’t been cleaned properly and you’ll probably find black gunk (and small brass shavings) in the ejector and extractor recesses.
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here are three videos that explain how to properly disassemble and clean AR-platform rifles. And then they cover the essential lubrication ARs need to run reliably.
Take-Down and Full Cleaning of AR15 by Jerry Miculek
Here ace shooter Jerry Miculek takes down and cleans an AR-platform rifle belonging to his daughter Lena. This is a good video because Lena’s rifle was “run hard and packed up dirty” so you can see where carbon and grease build up. This 35-minute video is very thorough. Jerry is one of the nation’s top action carbine shooters, so listen carefully to his advice on cleaning and lubrication.
General AR-15 Maintenance and Lubrication
There are various schools of thought on AR lubrication. Some guys like to run “wet” with lots of CLP, while others choose to focus lubrication on the key spots that receive the most friction and wear, such as the contact point for the bolt carrier. We do advice check the ejector recess and extractor spring recess frequently as gunk can get in there, causing malfunctions. Here is a good video from Pew Pew Tactical — a 7-minute guide to cleaning and lubricating AR-platform rifles. This shows important details for both the upper and the lower.
How to Clean Your AR-15 Bolt Carrier Assembly
This video offers very specific advice on the bolt carrier group, which receives the dirty gas directly from the barrel. Be sure to check the extractor and ejector recesses. That’s where old lube, brass shavings, and carbon accumulate. Follow the directions in this video for lubrication, and don’t over-lubricate the bolt carrier — that will only capture more carbon.

5. Gas Block: You want a gas block that does not impose pointed stress on the barrel. Clamp-on types that grab all the way around the barrel are excellent. The blocks that are pinned on with tapered pins that wedge against the barrel or the slip on type of block with set screws that push up from underneath (or directly on the barrel) can deform the bore inside of the barrel and can wreck the accuracy of an otherwise great barrel.
