Andro Corp Industries ACI-15 CQB 5.56 NATO 8" 30rd Pistol

The ACI-15 CQB is Andro Corp's short barreled 5.56 AR pistol, and the 8" barrel is the whole point of it. Inside a house or a vehicle, eight inches of barrel turns corners that a carbine argues with. A pistol length gas system runs the gun off a .750 low profile gas block under a 7" M-LOK handguard, and the barrel is nitrided and threaded at the muzzle. The bolt carrier group is an M16 profile unit, so the gun runs the same internals every other AR does.

The upper is machined to mil spec dimensions with T markings on the receiver and includes the forward assist, dust cover and ejection port assembly a full featured upper should have. Lower parts are mil spec, the grip is an A2, and an SB Tactical SBA3 adjustable brace sits on the back of the tube. Both receivers are hard anodized black. One 30rd magazine is included. A 5.56 fired from an 8" barrel gives up velocity and makes a lot of noise, which is why guns this short are usually bought as suppressor hosts or as compact defensive guns where handling beats ballistics. If that is the job, this is a correctly assembled example with no proprietary parts anywhere in the build.
