BCM® Upper Receiver - M4 Flat Top (M4 Feedramps) Complete (Unassembled) - DEMO/Scratched

These uppers are a great deal for the price. All of my really accurate Ar-15s have used these. I have a half dozen of these and out of 6 one has a small scratch on it. These uppers mate up really tight to the barrels I use. Highly recommended, Great Value

Excellent Deal

These have to be the best deal on a complete upper out there. They come with the parts kit and mine has maybe one small scratch if you looked real close. Great deal!

BLEM Stripped Upper

Excellent quality. Just one light scratch down the left hand side, otherwise perfect. If you aren't to concerned about the cosmetics of your gun, this is definitely the way to go.

Since I have been buying from BCM everything product that I ordered has been shipped faster than any other company even during this pandemic. I have not been able to get out and test everything yet but it all looks good and feels of good quality and I have no doubt it is durable. The BCM demo upper I bought is in great condition and im happy I finally bought one I assembled it and everything fits good. Thank you BCM.

Great buy

Posted by Matthew Scoope on May 18th 2020

I purchased two of these. The only "blem" was a small scratch. Small enough that just a small amount of oil covers it up. Barely even noticable. These are fantastic for keeping the cost down when building, but still using quality parts. Will not only purchase this again, but would highly recommend it to others.

BCM Upper Receiver

Posted by Spooky Dave on May 16th 2020

The BCM Upper Receiver is one the most reliable upper out there. Next to their BCG this is a required for all of my AR builds. May it be a patrol rifle to a 3 Gun or Varmint, I choose BCM.
