Excellent Upper

by -

This receiver is machined well and went together without issue. I have had a couple uppers during Covid times machined out of alignment or spec (I'm looking at you WMD), this Expo is NOT one of them. It is good to go out of the box. Even the face of the barrel threading was square and didn't require lapping. The price makes this a great value.
