RRA BLK1700DS LAR-15M 300AAC 16

The Rock River Arms BLK1700DS LAR-15M 300 AAC 16-inch rifle is a purpose-built platform for intermediate-distance rifle work with the .300 Blackout cartridge. This AR-pattern rifle combines a precision extruded aluminum A4 upper receiver with a 15-inch free-float M-LOK handguard, delivering the accuracy and modularity that serious shooters demand for both subsonic and supersonic load applications. The included threaded barrel and A2 flash hider accommodate suppressors, making this an excellent choice for operators prioritizing sound signature management.

Key specifications reflect combat-proven engineering. The 16-inch barrel length balances velocity retention with maneuverability in confined spaces—critical for clearing work and vehicle operations. Rock River Arms' single-stage trigger provides clean, predictable break characteristics suited for precision shooting and controlled fire. The free-float handguard eliminates barrel contact, ensuring consistent accuracy across different shooting positions and environmental conditions. At 15.48 pounds, the rifle maintains a practical carry weight for extended deployments. The aluminum receiver and stainless components resist corrosion in harsh field conditions, and the included polymer magazine provides reliable feeding across both subsonic and standard loads.

This configuration serves operators, LEOs, and serious riflemen who prioritize the .300 Blackout's intermediate ballistics and suppressor compatibility. The LAR-15M platform excels in short-to-medium range engagements where the .300 Blackout's terminal performance and subsonic capability provide distinct advantages. M-LOK mounting points support modern optics, lights, and accessories without rail bloat. Whether for specialized duty applications, suppressed precision work, or specialized training, the Rock River Arms BLK1700DS delivers known-good reliability with no-frills professionalism.
