Rock River Arms SOC1820.V1 LAR-15M CLB Carbine Operator .458 SOCOM 16" 30+1 Semi-Auto Rifle

The Rock River Arms LAR-15M SOC1820.V1 is the CLB Carbine Operator chambered in the hard-hitting .458 SOCOM cartridge. Built on the proven AR-15 platform, this semi-auto tactical carbine pairs a heavy 16" chrome moly bull barrel with a 1:14" twist optimized for the big-bore round.

The free-floated M-LOK compatible handguard keeps the barrel cool and provides a modular mounting surface for lights, lasers, and grips. Up front, an RRA Beast Brake tames recoil at the muzzle, while the steel receiver carries a blued/black finish. The optic-ready rifle ships without iron sights, letting the shooter mount their preferred scope or red dot directly to the upper.

The action runs through an RRA two-stage match trigger tuned for clean, repeatable breaks. The RRA 6-position Operator stock in black adapts length-of-pull to any shooter or situation. At 37" overall and 7.6 lbs, the SOC1820.V1 balances maneuverability with the mass needed to manage .458 SOCOM recoil.

Rock River Arms rates this CLB Carbine for 1.5 MOA accuracy at 100 yards. The rifle ships with one magazine, a case, the manual, and warranty information.
