The ultimate AR9 rifle, now in a convenient build kit. Chasing maximum accuracy with the 9mm cartridge was never easy — until now. We’re pairing one of the most popular AR9 upper assemblies we’ve sold with an AR build kit, allowing you to more easily complete your 16″ 9mm rifle, for less. Up top is…
Push 9mm Parabellum’s accuracy and distance to the limit with a 9mm Rifle Kit.
The 9mm cartridge was developed for traditional handguns: It only needs a barrel measuring 3″ to 5″ to provide adequate power and range. But if you load 9mm into the AR-type rifle and send it downrange through 16″ of quality MOA-capable rifling, you’re going to enjoy some serious accuracy out of a round you once thought was useless beyond 50 meters. Unlike many blowback pistol rounds, the 9mm will continue to build velocity — even in a barrel measuring up to 18″. In fact, you can achieve serious speed with a 16″ barrel: Around 1,400 to 1,700 FPS or more with a 90-grain to 115-grain load.
Why not? This is one of the only cartridges capable of providing semiautomatic fire in the AR platform without any gas block or gas tube. The longer the barrel, the heavier the gas system. Sticking with 9mm, you get to ditch all that weight and mess. Plus, a 16″-barreled 9mm AR provides plenty of wiggle room to load supersonic or heavy subsonic loads, achieving supreme accuracy with either. Grab some of that popular, ultra-dense Federal 150-grain, add a suppressor (with an approved NFA registration, of course) and you’ve got a heavy hitter that’s quiet and incredibly accurate. Think of it like a lighter, flatter-shooting 300 BLK subsonic, but with less kick and no finicky gas system.
