Can someone help me find out what bolt this is please. It is off of a half block. I need a slightly bigger bolt since I have blow back. An impulse bolt does not match up correctly with my pattern so that wouldn't work. I am thinking about getting a shocktech bushmaster bolt but I don't know if it would line up either.
