Description
The Rock River Arms LAR-BT9G is a 9mm Luger AR-pattern carbine from RRA’s CAR A4 series, purpose-built as a dedicated 9mm rifle with Glock-pattern magazine compatibility. American made and custom built, this semi-auto carbine delivers the familiar AR-15 manual of arms with the economy, low recoil, and magazine commonality of the 9mm Luger cartridge.
Up front sits a 16″ barrel cut to a 1:10 twist rate for stable performance across a wide range of 9mm bullet weights. The barrel is threaded and ships with a standard A2 Flash Hider installed. A polymer drop-in handguard keeps the front end light and snag-free for general range, training, and defensive use.
The upper and lower receiver are machined from aluminum with a black anodized finish. The semi-auto action feeds from Glock-pattern magazines, and the lower carries the standard RRA controls, including a safety selector switch and a single-stage trigger. Sights are not included, allowing the end user to equip the optic and back-up iron configuration of their choice on the flat-top receiver.
A black RRA 6-Position Tactical carbine stock provides adjustable length-of-pull, paired with a black Hogue rubber pistol grip for positive control under fire. At 36″ overall and 7.10 lbs, the LAR-BT9G is a well-balanced 9mm carbine purpose-built for shooters who want a modern sporting rifle in the 9mm Luger chambering.
