The Bravo Company Manufacturing M4 Upper Receiver Assembly is professional grade weaponry. Precision machined to MIL-SPEC from a 7075-T6 aluminum forging provides this upper with exceptional strength. The inside diameter of the receivers threaded bore has been slightly undersized to provide a tighter fit with the barrel extension, resulting in a more accurate rifle.

NOTE: Please use a heat gun or hair dryer to warm up threaded bore of receiver if barrel extension is too tight.

Features:
  • Laser engraved T-markings
  • No BCM logo etched on the rear of the rail
  • Marked BCM4 over the gas tube port
  • 7075-T6 aluminum
  • Factory assembled forward assist, and ejection port cover
  • Hardcoat Type III, Class 2 anodized
  • Dry film lube on interior bore per MIL-SPEC
  • Made in the U.S.A.

Outstanding product!

Receiver is a bit undersized but BCM did that on purpose. I borrowed the wife’s hair dryer to heat up the aluminum a little and my barrel slid right in with no issues.
I will definitely be buying more of these for my future builds.

Wow

The fit of this barrel is maybe too good. It took me a long time to get the barrel in but it was worth it. I could not ask for anything better here.

SO TIGHT

LET ME TELL YOU... I did not have fun with this upper. Trying to get a 16" FN Barrel in took forever. The information that comes with the upper suggests a heat gun "might" be needed. No, it is. I went the round about way and had my brother help me by blasting the upper with a blow dryer and slowly working the barrel in with a mallet. It got there but it wasn't fun.

BCM quality

Excellent fit and finish, super snug fit with my SOLGW barrel. It had a instructions sheet saying you might need to heat it but I didn’t think I would need to lol. Sho nuff had to give it some heat.

BCM M4 Upper Receiver

by

BCM quality is second to none. This upper receiver shows it, but not their BCM logo- little disappointed about that, but no big deal. Barrel fitment is snug but easily installed if you follow their instructions. I installed an FN barrel with this upper and covered it with their MCMR MLOK handguard. Overall, this a very nice upper receiver that I would highly recommend. Pricing is always good at Primary Arms— thank you-Semperfi
