Pistols and Carbine models feature GLOCK® magazine compatibility
Colona, IL – Rock River Arms, one of the industry’s most respected names in Modern Sporting Rifles and pistols, is now shipping a new series of semi-autos chambered in 9x19mm. Designed to work with GLOCK® style magazines for optimal cross-compatibility with GLOCK back-up carry pistols, the BT-9 series takes shooting fun and personal defense systems to new levels.
The BT-9 models are based on RRA’s billet aluminum lower receiver with a GLOCK-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. Also, a common feature to all BT-9 models is RRA’s latest extruded aluminum upper receiver. The pistols are standard with RRA Lightweight Free-Float M-LOK-compatible handguards. Read more
