travis's Review of JP Enterprises .936 Adjustable Alum. Gas Block

This is my second jp enterprise gas block and if I am to build another none 223 AR I will definitely buy another gas block from JP. I have had no issues with these at all. I have used it for a 7.62 x 39 build and also a 204 build. I like these because they clamp together you don't have to grind a flat on your barrel for a set screw. Neither one of my guns have had the gas block move. The 7.62 x 39 has had 1000's of rounds through it and not a bit of problem. That one is a .75 gas block. The 204 hasn't had very many rounds through it and it is a .936 gas block. I would definitely recommend this to anyone building a off caliber AR 15. You will need it to dial in the gas pressure for proper bolt function.
