Thanks for the Range report KC-Joe. As long as your not seeing any gas leakage around the gas key on the bolt carrier or gas block you might just need to open the gas block more. PSA has used two different style of gas blocks on their 6.5 Grendel uppers. Each gas block has an adjustment screw and a retention lock screw. There always seems to be confusion as to which screw increases or decreases gas. My PSA 6.5 Grendel upper came with no instructions on the gas block settings. You can do a search on this forum as this topic has been discussed a few times.
It is not uncommon to get a little gas leakage on new gas block but these usually seal up with carbon from shooting in a few rounds.
Here is a link for the google custom search for the 6.5 Grendel forum. This is a great tool for finding information in this forum.
