J.p. adjustable gas block - JP Enterprises .936 Adjustable Alum. Gas Block

Has a low profile and fits under various hand guards, I used it to fit under a Seekins rail and it worked perfectly. When tapping the gas adjustment hole with the bottoming tap be sure to use a good quality one. My bottoming tap broke off inside the gas hole. I called J.P. and told them what happened and the shipped me a new one free of charge. Even though it wasn't there fault, they still mailed me a new one. Can't ask for better customer support. Now that it's mounted it works great, easy to adjust gas pressure and lock in place with a set screw.
