New Pistol Brace LAR-15 Pistols From Rock River Arms

Rock River Arms has announced two new configurations of the LAR-15 pistol. The new pistol brace LAR-15 models feature the SBX-K pistol brace from SB Tactical, a shortened version of the original SBX brace.

The new LAR-15 pistols will be offered with two barrel options chambered in 5.56mm, 7-inch and 10.5-inch, both made from Chrome Moly with a chrome lined bore and a 1:9 twist rate. Covering the barrel is a lightweight aluminum handguard featuring M-LOK compatible slots in a 6-inch length for the 7-inch barrel and a 9.25-inch length for the 10.5-inch barrel.

Rock River used forged upper and lower receivers on the pistol, even going so far as to mark it for “Pistol Only” on the magwell. As best we can tell, the lower is similar to the ones used on the rifle LAR-15 builds. Additionally, RRA added a Houge pistol grip, standard Mil-Spec lower parts kit, and an A2 flash hider.

The new pistols will start at $940 MSRP and go up to $960. Learn more on the Rock River Arms website.

Colona, IL– Rock River Arms, the leader in specialized Modern Sporting Rifles and purpose-built tactical firearms, adds two new 5.56 NATO chamber pistols to their LAR-15 line. These new semi-auto pistol variants were developed to provide enhanced stability and improved overall performance of the AR pistol platform.

The new A4 5.56 NATO-chambered pistols feature the field-proven SBX-K Pistol Stabilizing Brace designed by SB Tactical. The SBX-K is a shortened version of the original SBX brace, with a lower profile for improved operational handling and on-the-go maneuverability. The advantage of the SBX-K brace is that it offers an additional contact point for shooters beyond the grip and pistol fore end. When used in compliance with applicable jurisdiction laws, the SBX-K brace provides the shooter the option of a cheek weld or securing the brace to the forearm (via an adjustable hook-and-loop strap) for improved stability, muzzle control, and accuracy. As a BATF-compliant part for legal use on a pistol platform, the addition of the SBX-K brace on the new LAR-15 models makes these pistols a viable and reliable option for those looking for a compact at-home or on-the-go personal defense firearm.

The Rock River Arms A4 pistols come in two configurations—one with a 7-inch barrel and 6-inch extended length aluminum free-float RRA lightweight handguard, and one with a 10.5-inch barrel and 9.25-inch mid-length lightweight aluminum free-float RRA handguard. 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 with the SBX-K arm brace utilize chrome-lined barrels for durability and long life, RRA's forged LAR-15 lower receiver, an A4 upper with Picatinny rails that witness to the handguard rails, a single-stage trigger, and a rubber molded Hogue grip.

For optimal close-quarter handling and compact, discrete transport in a pistol platform developed for maximum accuracy potential and reliable performance, the new Rock River Arms A4 pistols featuring the SBX-K pistol brace are the obvious choice for discerning shooters and defense professionals alike.
