Rock River Arms OP1510 LAR-15M Operator DMR 5.56x45mm NATO 16" 30+1 Semi-Auto Rifle

The Rock River Arms OP1510 LAR-15M Operator DMR is a purpose-built AR-15 carbine chambered in 5.56x45mm NATO, tuned for the designated marksman role and ready for duty, defense, or range use.

Built on Rock River Arms' proven LAR-15M platform, this Semi-Auto rifle runs a 16" steel barrel with a 1:7 twist for stable performance with a wide range of 5.56 and .223 Rem ammunition. An A2 flash hider keeps muzzle rise in check on follow-up shots, and the carbine stretches to an overall length of 36.50" while weighing 7.20 lbs.

The Operator DMR wears a BCM SOPMOD stock for a solid, adjustable cheek weld and a 13" lightweight M-Lok handguard that keeps the front end light while providing plenty of real estate for accessories. Up top, Magpul MBUS Pro front and rear sights are installed for dependable iron sighting, with a Picatinny rail section ready to mount an optic. An aluminum receiver finished in Blued/Black anchors the build, and an Hogue Beavertail grip keeps the rifle planted in the shooter's hand. The OEM two-stage match trigger offers a clean, predictable break for precision work at distance, and the familiar safety selector switch controls the fire group. A right-hand layout, 30+1 capacity, and one included magazine complete the package, backed by Rock River Arms' reputation for hard-use, duty-grade ARs.
