Rock River Arms LAR-15M .300 Blackout 16 inches Threaded Barrel Rifle

The Rock River Arms LAR-15M .300 Blackout 16 inches Threaded Barrel Rifle represents a purpose-built platform for operators who demand subsonic capability without sacrificing modularity or reliability. Chambered in .300 Blackout, this rifle excels in suppressed operations, close-quarters engagements, and tactical applications where sound signature matters—critical for law enforcement breacher teams, military special operations, and civilian defensive marksmen. The 16-inch barrel length balances velocity retention with maneuverability, making this an ideal choice for vehicle-based deployments and confined-space operations.

Rock River Arms engineered the LAR-15M platform on the proven AR-15 foundation, ensuring compatibility with standard tactical accessories and maintenance protocols familiar to military and law enforcement professionals. The threaded muzzle accommodates suppressors, compensators, and muzzle devices without additional adapters, while the free-floating barrel design maximizes inherent accuracy—essential for precision work at intermediate ranges. At 15.48 lbs, the rifle maintains controlability in tactical environments while the 39.7-inch overall length fits standard gun safes and vehicle storage without compromise. Rock River Arms' quality control and use of American-sourced components ensure consistent performance across thousands of rounds.

This rifle serves operators who prioritize suppressed fire capabilities and need a compact, reliable platform for duty or home defense. The .300 Blackout cartridge delivers superior terminal performance in subsonic loads while maintaining supersonic velocity options for extended-range work, offering flexibility that 5.56 NATO cannot match in this application. The threaded barrel is fully compatible with standard 1/2x28 suppressors, making this an immediately operational system for those with appropriate licensing. Shooters familiar with AR-15 ergonomics will find zero learning curve, while the modular design allows future upgrades to furniture, optics mounting, and caliber conversions as mission requirements evolve.
