Brownells Gun Tech™ Caleb Savant shows us how to install the Brownells Wrenchman Lightweight Handguard for AR-15. The first step is to make sure you have everything in the box: the Wrenchman LW itself with barrel nut, barrel nut wrench, Allen wrench, and the instruction sheet. Start by removing the barrel nut from the handguard using the Allen wrench. Put a little Brownells Action Lube Plus or any similar grease on the barrel extension and insert it into the upper receiver. Slide the barrel nut
The AR-15 was originally designed as a military rifle, so it was meant to shoot military ammunition - not all of which is safe to shoot at your local range. According to Brownells Gun Tech™ Caleb Savant, the M855 variant of 5.56 NATO has a steel core. It's not technically an armor-piercing round, but it can damage steel targets and backstops pretty easily, so most public ranges don't allow it. M855 is easy to identify because the bullet has a green tip. Other forms of .223 Remington or 5.56 NATO
Remember those "compare and contrast" essay questions on mid-term and final exams in school™ Caleb and Steve are talking AR-15s again, comparing the relative advantages of a factory rifle from a gun store, one built by a custom shop, and one you build yourself. A store-bought factory AR-15 is the easiest way to go. You know exactly what you're getting, and you don't have to hunt down individual parts and/or wait your turn in a custom shop's backlog. The gun was probably function tested at the fa
Do you really need a .22™ Just about everybody learns to shoot with a .22 rimfire rifle, and but that's kid stuff, right™ Once you grow up, you shoot guns in grownup calibers, and leave the .22 behind. Or do you™ Brownells Gun Techs Caleb and Steve say, "No, you don't!" A rifle, pistol, or revolver chambered in the classic .22 Long Rifle cartridge is THE most versatile gun you can own. It's great for plinking, varmint hunting, inexpensive target practice, and learning the fundamentals of marksma
Blueprinting a rifle action involves truing it up and tightening its tolerances to match those specified in its original design plans or, to use an old term, its blueprint. Brownells Gun Tech™ Caleb Savant gives us an overview of blueprinting an action using a Remington 700 as an example, but these principles apply to almost any rifle. The goal of blueprinting is to maximize the rifle's accuracy by making everything perfectly concentric to the bore itself. This involves truing up the shoulder an
One of the advantages of the Super 42 AR-15 buffer from Geissele Automatics is that you can easily change the weights inside. It's easy IF you know the trick for doing it. And today Brownells Gun Tech™ Caleb Savant shows us how it's done. The Super 42 buffer usually comes from the factory as an H1 buffer, and by changing the weights inside you can turn it into an H2, H3, or even a standard 3 oz. carbine buffer. The steps: (1) Remove the buffer from the spring. (2) Ease out the roll pin that anch
Hiperfire's Hipertouch AR-15 triggers have earned an excellent reputation for enabling the AR shooter to put a smooth, precise, clean trigger on his or her rifle. Unlike traditional AR-15 triggers, the Hipertouch system uses TWO coiled springs for the hammer, and Hiperfire includes multiple pairs of hammer springs with each trigger, so you can swap them to adjust the pull weight. Heavier springs will help ensure reliable ignition of ammo with hard primers, while lighter springs will give you the
How low can you go™ That's the question Brownells Gun Techs Caleb Savant and Steve Ostrem answer today - in the context of mounting a rifle scope on your AR-15. The old rule of thumb is that you should get the scope as close to the centerline of the bore as you can. So mount that scope really LOW on your AR, right™ The guys say "Nope!" The top of a flattop AR-15 receiver is pretty close to being in line with the top of the stock. If you mount a scope that low, you won't be able to get your head
If you're an experienced reloader, a beginner, or even if you've just read a reloading manual, you know that overcharging a case - putting too much powder in it - is very dangerous. Brownells Gun Tech™ Caleb Savant warns us about a lesser-known problem. Undercharging - not putting enough powder in - is just as dangerous. When the powder is spread out inside the case, its surface area is unusually large, and the primer can ignite ALL of it at once, rather than burning more slowly from back to fro
Brownells Gun Tech™ Caleb Savant has a really helpful tip for anybody installing a low-profile gas block on an AR-15. Two questions: (1) Are there setscrews on the underside of your gas block to anchor it to the barrel™ (2) Does your barrel have a "dimple" on it 180-degrees opposite the gas port™ If your answer is "yes" to both questions, Caleb's tip is for you. (Hint: Gas block manufacturers use that rear setscrew hole to align the drill that makes the hole in gas block for sending gas from the
Loading / reloading your own ammunition isn't just a matter of dumping powder in a case, seating a bullet, and heading off to the range! Brownells Gun Techs Caleb and Steve have some tips on how to develop SAFE loads that will do what you want them to do. The key is a good reloading manual. In fact, if you're starting out, get the manual (or manuals) even before you buy your reloading equipment. The loads in the manual were developed under laboratory conditions to help ensure they don't produce
Brownells Gun Tech™ Caleb Savant shows us step-by-step how to install a Midwest Industries G4 M-LOK® AR-15 handguard. Good news: it's an easy process. The G4 typically comes out of the box with the barrel nut, spacer, and screws installed. You'll have to remove them before you put it on the rifle. Is the barrel nut stuck in the handguard™ Watch Caleb's simple trick for extricating it. Now, install the barrel into the upper receiver. Don't forget the lube! (Caleb's using Brownells Action Lube Plu
