PSA 7.5” 300. Blackout upper on spikes lower
It has worked flawlessly subsonic ammo and supers without a hiccup over 200 rounds all while using a AAC 762 sdn 6 suppressor. I just installed a Franklin armory binary trigger can’t wait to get back out to the range. I had to trim just a bit off the handguard to give me clearance when mounting the suppressor.. On my next order I will buy one with a half inch shorter handguard to solve my issue.

Happy .300 Blackout.
For a 7.5 inch barrel, I was surprised with 3 MOA accuracy at 100 yards upon sighting it in with a Vortex Sparc red dot optic. Then my wife showed me it was 2 MOA.

Outstanding!
This was my first PSA upper purchase and I was very impressed. The quality, fit and finish were excellent, and far better than I expected for the price. I matched it with a generic lower from a local vendor. The final product is a highly reliable zombie gun that shoots 1 MOA at 50-yards.
