Fit, finish and operation are fantastic! Perfectly gassed with a Silencerco Omega. Not to mention the service, I cannot say enough about how fantastic these guys and gals are they took amazing care of me and my timeline with this purchase. A+++++

I ordered what I thought would be a nice assembled upper, and it has far exceeded my expectations.

This I'm my second upper receiver group purchase from BCM. The quality and accuracy are outstanding. Couldn't be more satisfied.

Purchased for NFA SBR using a JP Silent Captured Spring 2.0 (heavy) buffer.

Ran flawless with the following unsuppressed loads:
110g Supersonic
150g Supersonic
110g Subsonic (Trail Boss powder) did not eject spent case as expected with this load combination
208g Subsonic
220g Subsonic
I used different verities of Hornady, Barnes, and Sierra bullets
I highly recommend this upper. I will update performance with use of suppressor at a later date.

Absolutely love this upper. Fit and finish were perfect. I have not had a chance to group from a rested position, however the shooting I have done has cycled all ammo perfectly. It shipped the very next day, and I had it about 3 days later. Amazing considering most manufactures of AR uppers claim a much longer wait period. They also sent some free stuff, including an awesome hat which I wear all the time. Great product, great company!

So this upper completes my ultimate home defense SBR.

The upper sports a Trijicon MRO mounted to a Bobro 1/3 co witness mount. BCM medium latch charging handle, bcm keymod rail covers, Magpul pro mbuis, Thorntail 45 degree keymod / picatany light mount, and inforce wml light.

This entire setup unloaded weighs in at exactly 6 pounds! Very light fast handling rifle.

Shooting this rifle is a dream. Double taps no problem. A friend who shoots 5.56 sbr's stated he thinks this has less recoil. My defense load is 110gr hornady vmax and have shot about 100 rounds so far.

Accuracy well at 25 yards they are going through the same hole. At 50 yards if I rest it the shots are touching or close to touching. I did a standing 3 shot group unsupported which measured 1.5 inches so I say accurate enough!

Bottom Line I could not ask for anything more out of this rifle. It is solid and flawless. If your looking for a light weight go to war quality SBR or pistol look no further!

The upper fired every round I fed it, even the cheap ones. I shot over 300 rounds with zero hiccups. I matched it with an H2 buffer as recommended. It fit nicely on top of my Spike's lower with minimal play. This complete upper is definitely a Tier 1 product.

Doesn't get any better than this. The quality, weight, performance is all top notch. I used to build my own uppers but for the price of BCMs uppers I might as well just buy them already assembled with the quality parts. BCM is all I use now for my builds. Have a nice little collection of the free hats, magazines, posters, stickers, and key chains. Thanks BCM!

your online site is great, although i do have one suggestion:

while checking out, the font that you use for the text during the checkout process is MASSIVE. Like crazy crazy huge, and makes things very difficult to read. Would be much easier on the eyes with a normal-sized font.
