They may be familiar to some, but not every gunsmith knows the ins and outs of drill bits. Here are the basics.

The graceful, light, and distinctive L.C. Smith Hammerless Double sidelock is a favorite of American shotgunners. Here’s how to fix its most common problems. If you own a Smith and want to make it suitable to shoot again, or if you are presented a Smith to repair, here’s what you need to know about the shotgun.

In June 2010, Kahr Arms purchased Minnesota-based firearms manufacturer, Magnum Research, Inc., maker of the Desert Eagle Pistol and BFR Revolvers in .44 Magnum, .45 LC/.410 or .45/70. Kahr Arms offers a selection of other niche-type firearms, such as the “Tommy Gun” and Auto-Ordnance line of M1 .30 caliber carbines. In this video, Gun Tests Contributing Editor Roger Eckstine shows off two of the company’s big-hole BFR wheelguns.

Beretta USA introduced the BU-9 Nano as its entry into the pocket 9mm pistol category last September. Initial shipments of the American-made pistol left the Accokeek, Maryland factory beginning in November 2011, with a suggested retail price of $475. In this video, Gun Tests’ Contributing Editor Roger Eckstine gets a detailed explanation of how easy the Nano is to break down for maintenance. The Nano's modularity provides for simple disassembly and easy cleaning. Safely disassemble the pistol by first engaging the striker deactivator, a patent pending safety mechanism that eliminates the need to pull the trigger prior to disassembly.

While I have Vietnam combat experience with direct gas impingement (DGI) systems in the M16 rifle, I favor a piston system. My M16 operated well in combat, but I also made certain that it was cleaned quite frequently. A few years ago, out of nostalgia, I acquired a Bushmaster XM15E2S. I don't know if it had anything to do with the pace of life I have now, as compared to Vietnam in the 60s, but I noticed that my Bushmaster collected a lot of unburned powder grains in the action after just a few rounds. When I compared it to my AK47s, the AKs always ran cleaner than the XM15. Ultimately, I disposed of my XM15 and purchased a SIG 556. The SIG, being a piston rifle, runs much cleaner than the XM15. The lesson that seems to be taught here, is that piston systems are likely to run cleaner and more reliably than DGI systems.
