PSA 18” 6.5 Gas Block Adjustment
#1
Sorry to jump in with a question that has been beaten to death, but mine is the one that I believe is the front lock, side adjust, as the sliver screw on the right side is to the rear of the block. After reading some posts here and on other forums, with replies by Josiah, I have a question as to whether the front screw is actually a lock or if it just holds a detent? The front screw is tight, but the side screw can be turned, with resistance, but it doesn’t feel like there are “clicks”, unless I’m not turning it enough to get to a click. So has anyone determined if it is indeed detents for a click adjust? If I’m going to get the side screw to actually be locked in place, I’ll have to disassemble it and see what’s preventing the front screw from actually locking the side screw. In one post from Josiah on AR15.com, he mentioned the lock screw shouldn’t be messed with as it was a detent, but in other videos, people are loosening the front screw and adjusting the side, but that was a PSA 6.5 Creedmoor, so it may be different.

It’s not that big of a deal as the rifle functions fine, and I’m pretty sure the adjustment will stay put with the amount of resistance on the side screw. I hate to admit that I haven’t shot it much. Just zeroed it in with a few rounds in 2018 when I got it, and have been harvesting a few deer a year ever since. I think I’m up to a whole 18 rounds fired now, with 8 to zero and group, and 10 deer.
