Want to upgrade your AR’s trigger? Shooting USA and Brownells have created a video tutorial that shows how to remove a factory AR trigger and replace it with an upgrade. This video illustrates the procedures to follow and the tools you’ll need. Step-by-step, the video explains how to swap the factory trigger group for a self-contained ‘box style’ drop-in trigger module or a traditional (multi-part) trigger system with enhanced performance.
Many AR-15s come from the factory with a military-type trigger that has a long, gritty, heavy pull. Replacing that trigger is one of the best ways to improve your AR’s performance. You’ll be rewarded with a smoother pull, shorter take-up, and reduced pull weight. You will also have a choice between a single-stage and a dual-stage trigger.
The box-style, self-contained drop-in systems from companies like AR Gold, CMC, Timney, and Wilson Combat are the easiest to install. John Scoutten explains: “These self-contained systems … are very simple to install. In fact, all you do is remove the factory parts, drop in the whole system, replace your pins, and you’re done.” Conventional two-piece trigger groups are offered by DPMS, Geissele, JP Enterprises, and Rock River.
The key points of the video tutorial are also explained on the Shooting USA website with text and still pictures. Before you start your trigger project, review Shooting USA’s AR Trigger Upgrade Page. You’ll find helpful close-up photos on that page.
Brux Barrels, based in Lodi, Wisconsin, has earned a reputation for producing great-shooting tubes. Brux-made barrels have won their fair share of matches, and set some notable records in the process. A few years back, Rodney Wagner shot the smallest five-shot, 600-yard group (0.336″) in the history of rifle competition, using a Brux barrel chambered for the 6mm Dasher.
Folks often ask us why Brux barrels shoot so well. “What’s the secret?” they ask. We can only answer with what Brux explains on its own website: “To make a cut-rifled barrel you have to start off with the proper ingredients: the best steel available, skill, and experience. Since there are really only two main suppliers of barrel-quality steel, the skill and experience is what really makes a barrel maker stand out.” Here is how Brux’s co-owners, Norman Brux and Ken Liebetrau, explain all the procedures involved in making a Brux cut-rifled barrel:
Brux Barrel-Making Process, Start to Finish
We start out with either 4150 chrome-moly or 416R stainless steel double stress-relieved bar stock. The bar stock starts out at 1-9/32″ in diameter and 20-24 feet long so we cut it to length.
Step two is to rough-contour the outside of the barrel blank in a lathe.
Thirdly, the blank gets mounted into a Barnes gun drill. The cutter bit has holes through which oil or coolant is injected under pressure to allow the evacuation of chips formed during the cutting process. This is called “oil-through” or “coolant-through”. Without this, you wouldn’t want to even attempt drilling a hole 30” long and under ¼” in diameter. The combination of a 3600rpm and good flushing allows us to drill a beautifully straight and centered hole .005” under “land” diameter at a rate of 1” per minute.
Clean the barrel.
Next the blank is sent back to the lathe to machine the finished contour of the outside.
Clean the barrel again.
Now, the blank is sent on to the Pratt & Whitney reamer in which an “oil through” reaming tool is used to cut away the extra .005” left in the drilling process. The reamer makes an extremely accurate bore size and after it is finished the bore will have a better surface finish and will be at the proper “land” diameter.
Clean the barrel again.
In the sixth step we hand lap each barrel to remove any slight tool marks that may have been left by the reamer and inspect every one with a bore scope. If the barrel doesn’t meet our standards for surface finish and tolerance it doesn’t get any further.
Clean the barrel again.
The barrels then go onto the rifling machine which is responsible for cutting the all so familiar grooves in the bore. A caliber/land configuration-specific rifling head is used to progressively shave away small amounts of steel to form the rifling grooves. This is accomplished by simultaneously pulling the rifling head through the reamed blank as the blank is spun at a controlled rate. After each cut, the blank is rotated 90 degrees (for a four-land configuration) and after one full rotation (360 degrees) the rifling head is slightly raised to shave off the next bit of material. This process is repeated until we reach groove diameter.
Clean the barrel again.
Lastly, the barrel is hand-lapped again (to ensure a smooth bore), and a final inspection is performed with the bore scope.
The barrel is cleaned one last time, wrapped, packed, and shipped to [the customer].
Anyone reading this detailed description of the Brux barrel-making process will doubtless come away with a new appreciation for the time, effort, and dedication required to produce a premium match-grade cut-rifled barrel. Obviously, there are no easy shortcuts and great attention to detail is required each step of the way. As shooters we’re lucky that we have barrel-makers so dedicated to their craft.

Many short-range Benchresters have thought about converting their 6 PPC to shoot a 30BR for score matches, or a Dasher for mid-range (or even 1000-yard) games. That way you have a rifle that does double duty, giving you the most bang for your buck. Though an action with a PPC bolt won’t normally work with 30BR/6BR/Dasher cases with their larger .308-class rim (0.4728″ diameter), there is a pretty easy solution that allows you to cycle these bigger cartridges with a 6PPC-style bolt (designed to fit .220 Russian rims).
“Rebating case rims … lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle.” — Butch Lambert
Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.
To convert a PPC-boltface action to shoot the bigger cases you can spend a ton of money and buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.” Below is the lathe form tool Butch uses to rebate the case rims.
Forum member Rardoin’s handsome F-Open rig features the new Borden BRM-XD action.
One of the most popular items in our Shooters’ Forum is the ongoing “Pride and Joy” thread. Since 2009, Forum members have posted photos and descriptions of their most prized rifles. Here are some of the most recent “Pride and Joy” rifles showcased in our Forum. Do you have a gun you’d like to see featured there? Just Register for the Forum and you can add your favorite gun to the list.
Bill Goad’s 6PPC Hunter “Ranch Rifle”
Forum member Grimstod tells us: “This is the personal rifle of Bill Goad. He has been experimenting with it on several levels. It is shooting great and has several matches on it now. Please enjoy these photos. More can be found on the website www.PremierAccuracy.com. We like the subtle barbed wire effect on the stock.
Twin-Upper AR with Custom Wood Furniture
This very unique AR belongs to Forum member Nuto-BR. He tells us: “Here are the two uppers I built. The top one is am X-caliber in 20 Practical with 24-inch, 1:11″-twist barrel. The bottom one is a WOA in .223 Rem, with 20″, 1-12″ twist barrel. They both shoot 1/2 MOA or better. Both stocks are laminated Maple and Walnut. I reversed the order of the two woods to tell them apart.”
Two Dashers and a Rimfire for Fun
Courtesy Forum member Dan H., here are two red-stocked Dashers plus an Anschutz 54.30 (Benchrest Stock) to make it a trio. Dan says: “The Anschutz provides good practice in trigger-pulling. It’s amazing what you can learn from a rifle that is as sensitive as this one.”
Dream Hunting Rifle with Custom Camo
Here is Forum member TyDaws’s “Dream Hunting Rifle” in 6.5-280 Ackley Improved. We love the custom paint work by by Melodie Yarbrough. Smithed by West Texas Ordnance, this rifle features a Rem 700 action with fluted bolt, PT&G tapered recoil lug, and Timney 510 2-lb trigger. The barrel is a fluted 26″ 1:8″-twist Bartlein 5R #3 contour. On top is a Huskemaw Blue Diamond 4-16x42mm optic in Warne Maxima rings. That’s an Atlas bipod up front.
Three Guns for Mr. Big
Forum Member Mr. Big offered up another trio of rifles — two bench guns and a tactical rig. Mr. Big says: “Here are the rifles I shoot most: Farley 6mm PPC, Stiller .243 Win, and Rem 6.5×47 Lapua. They will do just about anything I ask them to…” Challenge: Can you identify the makers of the three different stocks shown in this picture (and the different materials used in each)?
Dasher in Robertson Spider Web Stock
Here is Forum member Vahena’s 6mm Dasher. It has a no-turn-neck chamber in a 28″, 1:8″-twist barrel with 1.25″ straight contour. This has an original Robertson fiberglass stock with spider web graphics. This rifle was originally built as a 6.5×284 with a fluted barrel. Now it sports a bigger barrel for a smaller cartridge. The front rest is a SEB Neo with counterweight up front.
We know some guys who make their own stocks, and others who do their own chambering. But consider this, Robert Carnell of Australia built his own state-of-the-art, water-cooled, tension-barrel Rail Gun, even including the action. That’s right, Robert even made his own action. Wow, this has to be the ultimate home gunsmithing, do-it-yourself project.
Carnell is an accomplished benchrest shooter and past Australian Sporter Class Champion. In 1993 he won a Silver Medal at the World Championships. But Carnell is far more than an ace trigger-puller. Robert is a skilled and creative “home gunsmith” who has crafted his own custom action and built his own railguns from scratch. Robert also runs the Austrialian Benchrest Bulletin website.
Home-Built Rail Gun — Aussie Innovation
Below are photos of one of Rob Carnell’s most amazing builds. This liquid-cooled, tension-barrel rail gun is a great example of self-reliant Aussie engineering. The barrel runs inside a coolent-filled, large-diameter sleeve, much like an old water-cooled machine gun. This is the fourth rail gun that Rob built, and the second fitted with a tensioned barrel.
Robert explains: “My railgun design has a 1.75″ barrel under tension inside an aluminium tube filled with radiator coolant. There is nearly a gallon of coolant, and the barrel stays cool no matter how many shots I seem to fire, or how quickly they are shot. The brass nut on the front rides on a nylon bearing and can be tightened to get the best accuracy. I am a believer in the ‘tuner’ idea and this seems to work for me. The main tube is thick-walled aluminium 600mm (24″) long. There is a flange at both ends. The flange at the back fits onto the barrel before the action is screwed on. The front flange is a press-fit into the tube, then there is a brass nut that fits over the barrel and screws against a nylon washer on the front flange. The Railgun’s base is aluminium and has the standard adjustments — windage, elevation and a sighter cam. In addition, there is a 1/10 thou dial indicator for windage. This allows me to zero the indicator and shoot my group. If I need to add a bit of windage for a condition, I can quickly get back to the original position if my condition comes back.”
Home-Built Action Uses Rem Bolt
Rob’s rail gun uses his own home-made stainless action, which features Panda-spec threads and a modified Remington 700 aftermarket bolt. Not bad for a do-it-yourself project we’d say! CLICK HERE to read how Rob designed and built the action.
Tonight (12/7/2016), Shooting USA television features the Remington Bicentennial — celebrating 200 years of continuous production by one of America’s most legendary companies. The history of Remington Arms is a remarkable story. No large American enterprise — not Ford, not General Motors — can match the 200-year continuous history of Remington. The Remington enterprise is nearly as old as the United States. This story began in 1816, when a young man, Eliphalet Remington II, wanted a rifle…
According to historians, Eliphalet told his father he wanted a gun, so his father told him to build one himself (Eliphalet had been trained as a blacksmith). And so, in 1816, Eliphalet did just that, with the help of a hired gunsmith to bore and rifle his barrel. Eliphalet then took the finished flintlock to a local shooting match. “And his gun shot well,” says Remington Historian Richard Shepler. “So neighbors and friends asked, ‘Could you make me a barrel?’ Over time there was more and more demand.”
By 1828, Eliphalet moved into a factory in Illion, New York. In 1845, he jumped at the opportunity to secure the first of many government contracts. When the Civil War broke out, Remington stayed busy producing firearms. While later in the 1890s during peacetime, Remington manufactured cash registers, sewing machines, knives and even the first successful typewriter.
Whether fulfilling government contracts during wartime, or manufacturing cash registers and sewing machines during peacetime, Remington’s story continues today, arming sportsmen, hunters and armies around the world.

Cerakote is an advanced, highly durable, heat-cured coating that offers excellent corrosion resistance when applied to firearms. Cerakote can be applied to both metals and plastics, and many top firearms manufacturers (and custom gun builders) now offer Cerakote finishes as an option on their shotguns, hunting rifles, and tactical arms.
While Cerakote is not difficult to use, application of Cerakote is not just a simple “spray and bake” process. Best results are achieved when firearms are carefully degreased and surface-prepped prior to application. The video below, produced by NIC Industries, the manufacturer of Cerakote, shows the application process from start to finish. If you watch the video you’ll learn the importance of careful, step-by-step product prep. Metals should be surface-blasted prior to coating, and curing times need to be adjusted to the material type (polymer vs. fiberglass vs. metal). Cerakote is offered in a wide variety of colors. Multi-color finishes, including camouflage, can be applied by a skilled operator.
The video above shows a professional technician applying Cerakote finish to rifles and pistols. All gunsmiths who plan to offer Cerokote finishes should definitely watch this video. NOTE: Cerakote Firearms Coatings are designed for professionals and should be applied by an NIC-trained application specialist or a coating professional with proper training and equipment. NIC Industries stresses that “it is critical to follow all these instructions”.

Can you buy a new firearm for fifty bucks? Yes you can, when the “firearm” is a stripped lower receiver, the key component of an AR15-type rifle. With an AR lower, you can build your own “black rifle” project, which could be a gun for Service Rifle competition, or a specialized varmint-slayer, or a rig for 3-Gun matches — the choice is yours. Once you have the serialized lower (which must be transferred through an FFL dealer), you can build your own project as you see fit, with the trigger, barrel, stock, handguards, and sighting system of your choice.
Right now Sportsman’s Guide is offering a great deal on Anderson stripped lower receivers. You can purchase the lower for just $49.99 ($44.99 for Buyer’s Club Members). These are good-quality lowers, with correct mil-spec dimensions, and precision-machined to ensure drop-in installation of aftermarket components. Crafted from 7075-T6 aircraft-grade aluminum forgings, the made-in-USA Anderson lowers have a hard-anodized black finish. The take-down pin has a standard 0.250″ diameter.
The Legal Brief is a feature of TheGuncollective.com that focuses on firearms rules and regulations. In this Legal Brief video, Attorney Adam Kraut explains key State and Federal regulations governing firearms, and explains how to ensure compliance with all applicable laws.
This five-minute video explains barrel length rules for rifles and shotguns, and also explains the best (and most fool-proof) methods to measure your barrel. In addition, the video explains how to measure firearm overall length. A rifle or shotgun which is less than 26 inches overall can also be classified as a “Short-barreled” rifle/shotgun subject to the NFA. NOTE: Under federal law “If the rifle or shotgun has a collapsible stock, the overall length is measured with the stock EXTENDED”.
Highlights of LEGAL BRIEF Discussion of Barrel Length and Firearm Overall Length
The ATF procedure to measure the length of a barrel is to measure from the closed bolt or breech face to the furthest end of the barrel or permanently attached muzzle device. ATF considers a muzzle device that has been permanently attached to be part of the barrel and therefore counts towards the length.
How to Measure Barrel Length: Drop [a] dowel or rod into the barrel until it touches the bolt or breech face, which has to be closed. Mark the outside of the rod at the end of the muzzle crown (if you don’t have a permanently attached muzzle device) or at the end of the muzzle device if it is permanently attached. Remove the rod and measure from the mark to the end of the rod. That is your barrel length[.]
Remember, if the barrel length is less than 16 inches, it is possible that the firearm could be a short barrel rifle (if you are building a rifle or it is already on a rifle) and if the barrel length is less than 18 inches, it is possible the firearm could be a short barrel shotgun (again if you are building a shotgun or it is already a shotgun). Both of these firearms would be subject to the purview of the National Firearms Act and would require the firearm to be registered accordingly.
How to Measure Overall Length:The overall length of your rifle or shotgun may also classify it as a Short Barrel Rifle or Short Barrel Shotgun. The overall length of a firearm is the distance between the muzzle of the barrel and the rearmost portion of the weapon measured on a line parallel to the axis of the bore. … If the rifle has a permanently attached muzzle device, that is part of the overall length. … If the rifle or shotgun has a collapsible stock, the overall length is measured with the stock extended.
Who wouldn’t like to save a cool hundred bucks, particularly on a BAT action? BAT Machine Co. in Idaho produces some of the most beautifully-machined, and smooth-running custom actions you can buy. There’s a reason so many world Benchrest and F-Class records have been set with BAT actions — they really are THAT good. The quality of machining, smoothness of bolt operation, precision of firing pin function, and general fit and finish are top-flight.
Right now you can SAVE $100.00 on all BAT Machine actions in stock at Bruno Shooters Supply. NOTE: This is a limited-time offer that applies to current, in-stock inventory only. All listed BAT action prices are a check or money order price. Any action purchased with a credit card will incur an additional 4% service fee. Moreover, there is an additional $40.00 for shipping per action, which must be shipped to a FFL dealer since the action itself is considered the “firearm” under Federal law.
