Bravo Company Manufacturing MK2 Barreled AR-15 Upper Receiver - 5.56 - 14.5" - MCMR-13

The Bravo Company Manufacturing MK2 Barreled AR-15 Upper Receiver brings BCM's patented MK2 improvements to a 14.5" build, giving shooters more rigidity and reliability than a standard USGI upper. This mid-length upper pairs a 14.5" barrel with BCM's MCMR-13 free-float handguard.

Features:

• 14.5" barrel chambered in 5.56 NATO, 1:7 twist
• MK2 upper receiver with redesigned internal geometry for added rigidity
• Gas expansion chamber and dual vents direct gas away from the shooter's face
• Shortened forward assist reduces knuckle strikes
• Chrome-lined bore and chamber, HPT and MPI tested
• 13" MCMR-13 free-float M-LOK handguard
• T-marked picatinny top rail with 3" rail section and M-LOK sling mount
• Bolt carrier group and charging handle not included

The MK2 receiver's redesigned geometry increases rigidity around the barrel extension, reducing deflection and helping maintain bolt lug alignment. The mid-length gas system is matched to the 14.5" barrel, and the barrel is cold hammer forged from Mil-Spec CMV steel with a Manganese Phosphate finish.

Because this barrel measures under 16", federal law requires it to be built into an NFA-regulated short-barreled rifle or an AR pistol — attaching it to a standard rifle lower without a compliant, pinned-and-welded muzzle device is not legal.

Bravo Company Manufacturing has built professional-grade AR-15 components trusted by U.S. military, law enforcement, and responsible citizens for nearly two decades, backing every upper with rigorous quality control.
