BCM (Bravo Company Manufacturing) MK2 Upper: New

Bravo Co. Mfg. (BCM) has beefed up its MK2 Upper without adding weight by redistributing material from non-essential areas.

Think it’s hard to improve perfection? BCM did just that by bringing the AR’s upper receiver into the modern era. Compared to the standard flat-top receiver, BCM’s new MK2 upper features notable advances without increasing weight. How’d they do it?

To start, BCM removed material from nonessential areas, which allowed them to add material to the top of the receiver, most notably around the ejection port, which is structurally the weakest area of the design. The beefed-up receiver results in a stiffer foundation to support the barrel, handguard and any accessories.

With suppressor use being so common, BCM also added gas expansion areas and channels near the charging handle to lesson gas blowback in a shooter’s face. Another noticeable tweak is a redesigned forward assist that minimizes material and moves its location closer to the ejection port. This makes it easier to access the charging handle without interference from the forward assist.
