sonyman74 Posted November 22, 2008 Share Posted November 22, 2008 Well, It was not nice. My M4 would not cycle after the first shot. Got home, took it off and can see where the gas pistons rubbed and was getting stuck. I will use my Dremel and see if I can make that spot a little bit larger and see if that helps.
