I am 100% satisfied with this purchase. I received it in the mail today, oiled the bolt, slapped it on my lower, mounted my 1-4 power scope and I hit the range. 90 rounds and not a single hangup and that's only because I ran out of ammo. I am completely satisfied with my purchase, Primary Arms (seller) and Anderson MFG (builder) with this complete upper.
