Great for my SPRish build, highly recommend.
Have put about 300 rounds through this upper. Using a P.A 4-14x44 with a Giessele SSAE & 77gr OTM I've nailed down sub MOA consistently. the lighter ammo gives me 2-3 inch moa. Quick ship on this order. Dissasembled, cleaned, polished and lubed as soon as I opened box. Went with this over stainless and I haven't been let down. Thanks PSA Would definitely recommend.

Some failures with 556 but not designed for that. Perfect 223 upper.

Great upper for a great price.
Great upper for the money. Functions flawlessly with the PSA lower I paired it with. Fit and finish is great. Will definitely buy another upper.

Great upper/warranty
Solid upper and great warranty/customer service. When I first took it to the range it had a failure to eject. Called PSA the had me a shipping label within minutes. Shipped back in about two weeks working like a charm with no cost to me!

Great Accuracy, Great Price
I used this upper for my first AR-15 build and it is super accurate. I have a Vortex scope mounted on it and it hits 12” steel at 400 yards with ease. Great so far I only put 200-300 rounds through it pretty light weight.
