    Great Value

    If you don't want a pristine safe queen...this is for you! Excellent quality, minor scratching on finish. BCM forge marked upper. I heat set the barrel because of the tolerances...FANTASTIC!

    Great Value

    Awesome value and a great fit. Can barely notice the blem as it was a slight scratch UNDER the charging handle slot. You wouldn’t be able to see it as soon as a charging handle was installed and installing one would cause more wear than the blem anyway. Will buy more, highly recommended.

    Awesome value

    Mine had the tiniest little scratch near the forward assist. I have upper receivers from BCM this “Demo” and a brand new one. I will say that the brand new receiver fits %100 snug with not a bit of play. The Demo is about %93-95 which is still way better than most but if you buy brand new first you might be spoiled and nothing else will do. But for $60 I’d put money on it that you won’t find anything better than a BCM demo receiver! I set my expectations low because it says “demo” but I was definitely blown away by the steal of a deal this thing is. Will buy at least 2 more! Thank you BCM for yet another excellent hook up!

    Bcm blemished upper

    I received my bcm upper I have 4 others that were complete uppers that were sent to my house that look amazing, I understand this was a blemish and you take a shot in the dark at what you will receive, I must say I’ll never buy a blemish again, the finish is terrible It doesn’t match the bcm Handguard at all. I expected to see a small scratch here for there but this one is a dull gray doesn’t look like it had a finish at all. Yes I regret the purchase, but It is what it is. Won’t buy another. Hope this helps anyone in the market to buy.

    BCM Upper Blem

    An anodizing chip smaller than a pin head. Use the rifle outside for a day and you’ll never notice it again. Great quality it would appear. I’ll buy more.
