Are the complete uppers and lowers for this build available individually? Or do I have to wait for this to come back in stock? If available, what SKUs in particular for the upper and lower. Are these the ones or no? It wouldn't let me post SKU numbers....

You just can't beat a PSA AR for the price. The quality is far more than expected. This is my 5th purchase from PSA and I can assure you, not my last one either.

Best deal from an American made company
Great complete upper for my PSA complete lower. Love my completed rifle. Runs super smooth with Federal Premium ammo. Wish the charging handle was a little bigger to make gripping it better but it'll do. Mine came without my back up sight and PSA sent me one within a week of ordering. Great customer service

Freedom Upper Mid Length
I was very pleased with this Upper Assembly. Very good fit and finish. Matched very well with PSA Lower Assembly that I had purchased earlier. I really like the Magpul hand guard. No problems or malfunctions when firing. I think PSA did a very good job of building this Upper, and also my Lower. I was looking for an affordable AR 15, and I believe I found it. First time owner of an AR 15 - Definitely would recommend this product.

Upper Receiver
Great upper receiver and I would have given this a solid 5, but the rear sight does not fit. The sight will not slide on, due to the receiver being a little to wide for the sight to fit properly without damaging the plastic polymer.

Awesome upper.
Excellent fit and finish, as my first AR it was a great experience using PSA for everything to build the rifle. I was able to achieve 1 minute groups consistently off a bipod with a 3x scope.
