Good Design, Ejection Port Cover needs workReview by
I had a little trouble with the ejection port cover not staying closed because of the non-standard port size. I ended up replacing it with a strike industries UDC and then filed it down enough to get good reliable fit. Otherwise it is a good upper that matched up perfectly with a POF lower.

Good Fit and FinishReview by
Built up this upper receiver to use with my QC10 Colt 9MM lower. The fit was good, very tight fitting with the lower with no wobble. ADCO 4.5" barrel installed without issue and Samson Evolution rail also installed without issues. Using a CMMG MK9 Bolt Assembly. Did standard pre-fire function tests with no problems, and 3 round test fire went without a problem. Used a VSeven lightweight dust cover which installed easily and fits well. No problems with case ejection through the smaller port.

Haven't been to the range to check alignment issues, but 3 round test fire showed nothing to be concerned about. This upper receiver is a quality piece, good anodizing finish a bit lighter than the lower, but even with no blemishes. I expect long term, good service from this upper.

Great delivery from Rainier Arms, thanks.
