Built on the AR-15 platform and made in the USA, this Bravo Company Manufacturing BCM4 uses a semi-automatic, direct-impingement system chambered in 5.56mm NATO. The rifle features a two-tone finish with an FDE upper and black lower, SAFE/SEMI selector legends, and a BCM-marked bolt carrier visible. Capacity is 30+1.
The 16 inch barrel is threaded and fitted with an A2-pattern birdcage flash hider. Its BCM MCMR-15 M-LOK free-float handguard provides a full-length 12 o'clock Picatinny rail, M-LOK slots at 3, 6, and 9 o'clock, and teardrop lightening ports. The flat-top upper includes a forward assist, brass deflector, and ejection-port dust cover.
Ergonomics and controls include an adjustable, collapsible polymer stock with an approximate length of pull range of 10.75-14.1 inches, a BCM Gunfighter-style textured tan pistol grip, a manual safety, and a curved trigger. The aluminum receivers and handguard keep weight down while maintaining rigidity.
Thoughtful upgrades include a Warhammer Mod 2 ambidextrous charging handle, an ambidextrous QD receiver end plate, and a BCM M-LOK QD sling mount installed on the handguard. Markings observed include BCM logos, MADE IN USA, BCM MCMR-15, and US PATENT 8904691.
