The Radical Firearms AR-15 MHR is a 5.56 NATO semi-automatic rifle built around MIL-STD upper and lower receivers and a 15-inch MHR free-float rail system. Its 16-inch Melonite-finished barrel includes M4 feed ramps and a threaded muzzle, while the free-float handguard provides a stable platform for accessories without adding pressure to the barrel.
