Rock River Arms, one of the industry’ most respected names in Modern Sporting Rifles and pistols, expands their series of semi-autos chambered in 9x19mm with the new BT92152. Designed to work with Glock style magazines for optimal cross-compatibility with Glock back-up carry pistols, the 4.5-inch BT-9 Pistol with SBA3 Arm Brace takes personal defense systems to new levels.

The 4.5-inch BT-9 is based on RRAs billet aluminum lower receiver with a Glock magazine-compatible flared magazine well. Integral to the lower receiver is a unique winter-style trigger guard that offers comfortable room for the trigger finger when wearing tactical or cold-weather gloves. The pistol includes RRA’s latest extruded aluminum upper receiver and comes standard with RRA’s 4.25-inch pistol length lightweight free-float M-LOK-compatible handguard.

Featuring a 4.5-inch chrome moly, 1:10 twist barrel with a Smith Vortex flash suppressor (1/2-36 threads), the BT92152 pistol incorporates the SB Tactical SBA3 pistol brace (with 5-position LOP adjustment) plus RRA’s overmolded A2 pistol grip and two-stage trigger for an ultra-compact and highly portable AR-platform 9mm pistol ideally suited as a home- or personal-defense firearm.
