Will my PSA .223 bolt work on this upper?
Bernie G on Jun 21, 2019
BEST ANSWER: yes, it will but individual bolts should be "married" to each barrel as they wear down together. if you decide to use the existing 223 bolt, it would be wise to check your headspace before going hot.
Is this a nice upper for adding a suppressor ?
Tom S on Jun 12, 2019
BEST ANSWER: YES! Be careful buying an upper with a barrel length only .5 inches longer than the hand guard. If you do, the suppressor might hit the front of the hand guard. This barreled upper has a barrel that is 1.5 inches longer, so the suppressor fits. You will have a small gap between the hand guard and the suppressor, but at least the hand guard won't heat up so much or as quickly.

I put this on my PSA lower pistol build & the rig runs great. Fit and balance is perfect and I still have money left to buy an optic. Thanks again PSA!
