The LAR-15 10.5in A4 Pistol features the SBX-K Pistol Stabilizing Brace from SB Tactical. Also, the SBX-K is a shortened model, utilizing a lower profile for improved operational handling and maneuverability. Additionally, it delivers an additional contact point for gripping beyond the grip and fore-end. Consequently, and depending on applicable jurisdiction laws, the SBX-K enables shooters to gain a cheek weld or secure the device to the forearm.
This Rock River Arms A4 pistol features a 10.5-inch barrel and 9.25-inch mid-length lightweight aluminum free-float RRA handguard. The RRA handguard is M-LOK compatible for accommodating desired accessories.
Chambered in 5.56 NATO for use with 5.56mm or .223 ammo, the A4 pistol utilizes chrome-lined barrel. Additionally, RRA's forged LAR-15 lower receiver and an A4 upper with Picatinny rails provide the backbone. Meanwhile, a single-stage trigger, and a rubber molded Hogue grip round out the package.
