LAR-15 Pistol 7-inch

Rock River Arms added two new 5.56-chambered models of the LAR-15 Pistol to the line, featuring the popular brace from SB Tactical. Rock River touts the new variants as having enhanced stability and greater overall performance.

The A4 pistol, chambered in 5.56 NATO, 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.

Rock River LAR-15 Pistol Features

The Rock River Arms A4 pistols come in two configurations. Firstly, one features a 7-inch barrel and 6-inch extended length aluminum free-float RRA lightweight handguard. Secondly, the other uses a 10.5-inch barrel and 9.25-inch mid-length lightweight aluminum free-float RRA handguard. Above all, both RRA handguards are M-LOK compatible for accommodating desired accessories.

Chambered in 5.56 NATO for use with 5.56mm or .223 ammo, the A4 pistols utilize chrome-lined barrels, 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.

In short, the Rock River Arms LAR-15 Pistol A4 is compact, providing discrete transport and close-quarter handling. Moreover, the SBX-K pistol brace enhances the platform to get the most out of a svelte AR-style pistol.
