A buddy got a Grendel upper from PSA this summer and we could not get the bolt to lock back no matter where we had the gas block adjusted. He sent it back and it was returned without any explanation on the ticket at all, but my guess was a new gas block as it ran perfectly afterwards. Or the gas port needed opened up. Runs like a champ now and holds 1/2 moa with 123 SST handloads.
