    As promised

    Looked great on the outside. Inside had some markings but nothing that would affect how it functions.

    I did lap both BCM upper receivers and found that the anodizing was very robust. It took several attempts with the lapping tool to complete. You can tell how tight the tolerances are as I had to be very careful inserting the lapping tool. Both were exactly the same.

    For comparison, I had two additional stripped uppers from a less known manufacturer that I lapped at the same time and it only took one pass to completely remove the anodizing.

    As a bonus, it comes with forward assist and ejection port cover (both not installed).

    Worth the money...these are a bargain.

    BCM Upper Receiver Demo

    This is about the fifth Demo upper I have ordered. Could not find much of a blemish on any. Saves a bunch of money.

    Great!

    Upper seems of solid construction, large blemish on the left side as advertised. Overall very happy with my purchase. FYI the it is absolutely necessary to heat the upper before putting the barrel on, it is an insanely tight fit.

    A great deal!

    The blemishes on the upper are minimal. I will be buying more. Dry lube coated, BCM4 marking on front of receiver and a nice tight fit on the barrel extension. Thumbs up. The included ejection port door appears to be a little cheap.
