So I have JP build that I recently acquired. It was built by a Marine Sniper Instructor so I know great time and effort was put into it. I am admitting I'm a little out-classed when operating this thing. Semi-auto precision platforms are new to me, and that includes using an adjustable gas block system.
I have read the instructions on tuning the adjustable gas blocks and being as the rifle is for LE competition use, it was recommended to have it in the "full-open" position to ensure reliability with various types of ammo. How far out exactly is the "full-open" position? I have a JP Enterprises JPGS-9D or 10D on my weapon. I am sorry if I don't know the exact model of gas block. I have the weapon operating somewhat reliably with 3 types of ammunition, but I want to ensure that I don't have the adjustment screw backed out too far. I am aware that migration is almost non-existent, but I still want to ensure that everything is installed correctly. The screw is much further out than I have seen on other rifles.
I did the tuning method starting with it closed and working back. The rounds eject and the weapon cycles, but I kept running into issues where the BCG wouldn't seat appropriately and I had to use the forward assist. The bolt was somewhat dry so I will clean it and try again to get an appropriate setting. I don't know if I should chalk that up to the gas block or another issue.
Thank you for your time.
