There’s nothing special about the four-rail free-floating handguard that surrounds the barrel, though Carlson told me they selected that particular handguard because it has a large internal diameter that makes attaching suppressors easier. Carlson notes, “Our guns look really great with a 5.5-inch barrel with a suppressor attached.” Keep in mind, since the gun is blowback in operation, there is no gas block or gas tube on top of the barrel. Lone Wolf redesigned the AR lower to release the Glock magazine from the front of the magazine well using a toggle paddle.Ī 10.5-inch barrel with 1:16 twist is used on the G9, but barrels cut all the way down to 5.5 inches can be custom ordered. If you’ve always wanted an AR SBR but were turned off by the volumes of paperwork and the intrusive nature of obtaining a tax stamp, the SB15 offers a completely viable alternative. In use, I found it as comfortable as an ordinary M4 buttstock. The BATFE initially issued a letter saying that it is perfectly legal for folks to shoot from the shoulder an AR pistol outfitted with the SB15. It will fit both commercial and military receiver extensions and slides on for friction fit. Originally designed to help wounded veterans shoot an AR pistol with one arm, the SB15 is legal for anyone to affix to their pistol. The SIG SB15 Stabilizing Brace deserves more than a casual mention here. SIG SB15 Stabilizing Brace was designed to help injured veterans shoot an AR pistol with one arm. It provides a comfortable length of pull of about 12 inches and is comparable to an M4 buttstock in its second position. This limits how far forward the SIG SB15 Stabilizing Brace can move forward. The advantage of this tube is that it features a lip about two inches back from the rear of the receiver. The receiver ring is reinforced, presumably for longer life, and LWD outfits the G9 with a KAK lower receiver extension (buffer tube). It can easily be removed and the lower used with a 5.7 upper if desired. LWD uses a 9mm ejector that is screwed into the receiver. Carlson tells me that LWD can modify your bolt if you were running a mag well block conversion with a double-column magazine.įield evaluations showed G9 to be significantly faster and more accurate compared to a conventional pistol.įor a nominal $45, LWD can re-work your bolt to run with the Glock tapered column mags, and all manufacturers’ uppers (with the exception of Olympic Arms) will then work with the LWD lower. ![]() From the mag well back, it is very much a standard AR lower.”īecause the G9 is blowback in operation, it does not utilize a locking bolt, instead relying on the bolt weight as well as the buffer spring to retard the bolt’s velocity and return it to battery. There was just no good way to do it with a filler block, so we redesigned the lower with a large paddle magazine release, and it is one of our most complimented features. Our design positions the Glock magazine toward the front of the receiver, and the toggle-style magazine release engages the right side of the mag. According to Carlson, “The AR mag release cutout is on the left rear side of the mag well. Zack Carlson, LWD’s Marketing Manager, told me that they had many requests for an AR magazine well insert or block that would allow the use of Glock magazines on a standard 5.56 lower. Starting with a 7075-T6 forging, LWD machines the lower’s magwell to accept Glock magazines without a filler or block. ![]() They knew they wanted to have a lower that was dedicated to Glock magazines. These too experienced problems when used with lighter 9mm bullets.įor field shooting, Detty used Trijicon RMR (Ruggedized Miniature Red Dot).īut LWD started with a fresh page when they designed the G9 lower. As years went by, many other AR manufacturers offered similar ARs chambered in 9mm utilizing a magazine well block similar to Colt’s and using modified double-column Uzi magazines. ![]() Shorter, lighter bullets always posed a problem for reliability. A magazine block filled the empty space in the magwell and possessed an ejector and feed ramp that directed the round from the magazine into the chamber. It used blowback operation and had a 32-round double-column magazine. Years ago, Colt developed a 9mm AR and sold it primarily to law enforcement agencies that feared the 5.56 NATO round would over-penetrate in urban environments (actually the opposite is true).
