    M4 flat top

    Posted by Ben on Sep 3rd 2019

    I purchased a blem and think I found the scratch it’s was very minor and I honestly can’t even tell . Installing the barrel was challenging and required a heat gun and force . Also required a heat gun and force to get the BCM hand guard over the barrel but. End result was an absolute rock solid upper . Completely satisfied and will use again

    Blem upper receiver

    Posted by Arthur Waterman on Aug 26th 2019

    Purchased a blem upper receiver. It had an obvious scratch on one side which wad fine with me since this will be a hunting gun and will have added scratches eventually from the field.

    Item was as described. Shipping was fast, with no issues. Very good value for the cost. I plan on using BCM products as much as possible to complete this build. Thanks

    Perfectly Functional

    Posted by Andrew Meade on Aug 20th 2019

    The only blemish on the receiver was a mark on the left hand side. Looks more like paint transfer than an error in the finish or a scratch. These do not have the BCM logo on the right hand side if you care about that. This is perfect if you plan to rattle can your gun anyway. Would buy again.

    Great option.

    Used this with a BCM ELW barrel. Very tight fit which I like. Excellent performance out of it so far.
