    Bcm m4 upper reciever blemished or scratched

    Great product and exceptional tollerance for barrel fit with well machined m4 feed ramps.I dont build safe queen rifles so a small nick or surface scratch that will eventually happen anyway does not bother me a bit. Thank you Bcm for producing quality parts at fair prices. This was actually my 3rd blemished or scratched upper reciever ordered and all 3 were recieved with very minor surface abrasions that easily buffed out with oil.

    Perfect

    Yes finish was blemished and scuffed but with hydrodipping in mind it was a perfect cost saver. I purchased the same upper for another build at full cost. With the new finish you'd never know it was blemished.
