great buy October 17, 2019 Reviewer: walter mcclung from turlock, CA United States   I was able to put a few rounds through my new upper yesterday and was very happy with the accuracy and performance. The barrel is not broken in yet but on target. Also the new KMR Alpha handguard is awesome. I love it size and feel not to big and bulky (lighter)  and still gives me the flexibility i wanted and thanks for the hat and stickers. Always looking for a new hat.....

20” upper April 10, 2019 Reviewer: John Garner from POMONA, CA United States   Decided to build an AR 15 full length 20” rifle. Shopped the internet but with a preference for BCM products. This purchase is a quality component at a reasonable price. Well engineered with excellent fit and finish.  Highly recommended! Was this review helpful to you?

Astounding December 28, 2016 Reviewer: Seth E. from Albuquerque, NM United States   So happy I decided to go with the 20 in upper.  Super quality, its very lightweight, and a vast improvement over my previous PSA carbine upper. I was just astounded at the craftsmanship when i took it out of the box. Well worth the money. Smooth shooting and very accurate, having only shot .223 Wolf gold out of it so far. The free float barrel seems to help out a lot, that along with the rifle length gas system lowering the recoil. BCM is an awesome company they even sent me all kinds of cool stuff like posters, keychains, stickers, and a hat with my order. Thanks BCM! Will heartily recommend! Was this review helpful to you?

Sweet as usual.......... December 28, 2016 Reviewer: Stephen Francone from Grass Valley, CA United States   The usual well put together Bravo Co. upper. Service prompt and delivery quick. Nice shooting complete upper. Like the KMR handguard. Thinking of changing all other uppers to KMR units. Would recommend buying ONLY from BCM Was this review helpful to you?
