Rock River Arms recently announced the addition of a new series of carbines and pistols, the BT-9 family. The new BT-9 series works with Glock pattern magazines, delivering compatibility with backup carry pistols and one of the leading aftermarket component segments.

Rock River Arms BT-9 Series Features

Rock River based the BT-9 models on the company’s billet aluminum lower receiver. That receiver also includes a Glock-compatible flared magazine well. The lower receiver also features an integral winter-style trigger guard that provides ample room to work while wearing gloves.

The BT-9 also features Rock River’s latest extruded aluminum receiver. Meanwhile, the pistol variant comes standard with a Rock River Lightweight Free-Float M-LOK handguard. Finally, the BT-9 series consists of three different models: a 7-inch pistol, 10.5-inch pistol and 16-inch carbine.

BT92133 Pistol

The BT92133 Pistol features a 7-inch moly barrel with 1/2-36 threads. It also incorporates the popular SB Tactical SBA3 pistol brace, which delivers 5-position length-of-pull adjustment. Rock River’s own A2 pistol grip and two-stage trigger complete this compact, highly-portable 9mm pistol.

BT92142 Pistol

The BT92142 Pistol features the same configuration as the BT92133, but with a chrome-lined 10.5-inch barrel for added durability and longer-range accuracy. Also, the pistol sports a 7.25-inch lightweight, free-float handguard.

R9 Competition BT91700

Stepping up another rung on the ladder in size is the R9 Competition Rifle. Further, this guns is built for competition, featuring a two-stage trigger, 16-inch chrome moly barrel and PRAGE 3G handguard. It also comes standard with Rock River’s 6-position Operator CAR buttstock and Hogue overmolded pistol grip.
