Used this on a 6.5 CM upper build. Works great with no cycling issues, blown primers, or damaged brass.
I simply loosened locking set screw [facing front] and adjusted the Gas Screw [facing right] 2 full turns open from closed. Then tightened locking set screw. Very happy with the results.
Note: I checked it before installation and on my PSA gas block 2 full turns from closed exposed 1/2 of the gas port. This would lead me to believe that the rifle would be over gassed without an adjustable gas block.

I also drilled-tapped- threaded the forward port where the gas tube is normally roll pinned into position and installed a 4-40 set screw with blue Loctite.
