“they say it's for a .750 barrel but it's too loose around the barrel and the top port was also too big for the gas tube so gas leaks out there also. it was only off a couple of one hundred thousandths but enough to make the gun not work.”
“Excellent Product. This is my second one. I have 2k through my first. No issues. Stays adjusted where you want it. Much easier to adjust than blocks that have an adjuster and a set screw. Will continue to use.”
