    Simply The Best

    Purchased 1 several months ago for a pistol build. Fit was tight. I heated it up and installed the barrel. Worked great. I ordered an Aero upper receiver for an ar rifle build. Fit was sloppy. I returned it and ordered another one of these. Fit again was German, Good-n-Tight. These UR’s are the best. I cant stand it when you can grab the upper and twist it and its just sloppy, and no, I dont want to be adding rubber bands to tighten it up. Just buy it. You cant go wrong.

    Blem uppers

    Bought 2 of these based on satisfaction with previous bcm products. I've been building ar's for a while, but first time using these uppers. Couldn't find the flaws. Will be using them again.

    Tight fit, but will make for a more accurate rifle. I just put mine in the oven on 300 for 5-10 minutes. No this didn’t hurt the finish. I only order these for the tight fit.
    I’ve order some without a single blem and I’ve received some with minor scratches.

    Upper receiver

    First, if it doesn’t say BCM you’re wrong. Always my first stop when doing a build. Great products at good prices and this upper is no exception. Keep it up guys.
