Built on Rock River Arms’ LAR-15M series, this rifle uses a flat-top upper with a Picatinny rail and a free-float aluminum M-LOK handguard that carries a continuous top rail for straightforward accessory alignment. The receiver is aluminum and marked LAR-15M and CAL. MULTI, with a STANAG-pattern magazine interface supporting a 30+1 capacity.
The 16 in barrel is threaded and fitted with a three-prong flash hider that has wrench flats and serrations for secure installation and removal. A low-profile gas block and direct-impingement operating system keep the front end trim while maintaining compatibility with the free-float handguard.
Controls and furniture emphasize practical handling. The charging handle is ambidextrous with an extended latch for easier access. The stock is collapsible with a rubberized buttpad, and the pistol grip is a rubber overmolded, finger-groove design. A manual safety selector provides positive on/off control. Length of pull is listed at 11.0 in.
Optics are already addressed with a Burris 1-6x24mm 30mm SFP Duplex Illuminated Dot LPVO mounted in a Monstrum one-piece cantilever mount. This setup provides a variable 1-6x magnification range with a 24mm objective and 30mm tube, giving the rifle clear, usable sighting from close to extended distances. Rock River Arms’ background includes DEA carbine contract history (2003), adding notable lineage to the platform’s credentials.
