This is a first build so my inexperience is probably showing here. I am trying to install a JP VTac handguard on a Mega upper with a Cardinal Armory barrel. The problem is that the barrel nut is not moving enough to line up with the gas tube opening. After doing the 35 ft. lbs. 3 times the inner nut is just past the opening. 80 ft. lbs. will not move it to alignment with the next hole. I tried backing the outer nut out one turn as suggested in the instruction but I had the same results. I will try a different torque wrench on the chance my old one is messed up for some reason but I am looking for ideas what to do about getting this upper together. Trapdoor |
