Robert Shields's Review of SLR Sentry 7 .750 Adjustable Gas Block w/ .450 in. Set Screw Spacing

Best bang for your buck, pun intended. I installed a lightweight BCG on a 300 blk out build of mine as well as this GB and this thing worked flawlessly easy to adjust and the spring detention positive click system worked amazing well done
