The Bravo Company upper comes with 10" MCMR M-LOK rail and an 11.5" barrel. The barrel has a continuous taper design for optimal weight, balance, and performance. The MK2 upper receivers increased rigidity limits barrel deflection which aids in consistency/accuracy. A gas expansion chamber is machined above the charging handle track, combined with dual vents machined at the rear (each side, above charging handle latch) help to redirect and vent gas away from the shooters face. Included with the BCM Upper Receiver Group is one 3" Picatinny Rail Section and one BCM MCMR Sling Mount.
