Andro Corp Industries ACI-15 Halo 300 BLK 10" 30rd Pistol

The Halo is Andro Corp's 10" build, and in 300 Blackout those extra couple of inches over the CQB buy a little velocity and a lot more usable rail without making the gun awkward. The 9" M-LOK handguard covers nearly the whole barrel, so a light, a sling mount and a hand stop all have somewhere to live and the muzzle sits close to the end of the rail instead of hanging out past it.

Mechanically it is a mil spec AR-15 pistol. M4 feed ramps, an M16 profile bolt carrier group, a pistol length gas system on a .750 low profile gas block, and a QPQ finish over the nitrided, threaded barrel. The upper is machined to mil spec dimensions and T marked, with the forward assist, dust cover and ejection port assembly fitted. The lower parts kit is mil spec, the grip is an A2, an SB Tactical SBA3 adjustable brace sits on the tube, and one 30rd magazine is included. Both receivers are hard anodized black. In 300 Blackout this is a natural suppressor host: subsonic loads cycle reliably off a short gas system, and the larger bore gives a can real work to do. Nothing here is proprietary, so upgrades come off the same shelf as every other AR part.
