I am trying to put a free float fore end on, but for\ound the barrel not is not exact for my rifle.
It appears the holes do not line up exactly (1/8" off) so as the gas tube won't slide in. This is close example of the barrel nut barrel nut The barrel nut goes on fine. The problem is it doesn't line up for the hole. My thought is to ream out the metal in the way, between the 2 holes. Is there a better solution??? Thanks |

Things I'd try to time correctly:
-- spec torque between 30 ft/lbs to 80 ft/lbs max with aeroshell 33ms grease on threads -- season threads (loosen and tighten) a few times (min 3) near torque spec closest to alignment (sometimes just gets it there a hair) -- barrel nut shims -- lap front of reciever just a hair or square by lathe (paladin machine shop will do cheaply) -- try a different side of barrel nut (ie, noveske nsr) or a different barrel nut (ie, if a standard brrl nut to achieve tolerance stacking in your favor) -- try mating the barrel to a different receiver Good luck |
