Piecing together an AR with a free float handguard. Problem is I put it on last night and cannot get the receiver hole to line up with the gas tube hole. The hole in the receiver is exactly half way between the two holes on the FF barrel nut. I cannot get the nut any tighter to move it over, and if I back it off it is too loose. How do I remedy this? Try and drill between the two holes? THANKS

Are you using a torque wrench? Just in case you haven't seen the procedure:
1) Tighten to 30 ft-lb, loosen
2) Retighten to 30 ft-lb, loosen
3) Retignten to 30 ft-lb, continuing up to 80 ft-lb in order to align gas tube hole
I have found that sometimes it's hard to turn the last bit with the extra leverage from a torque wrench. I've never had one that wouldn't line up before I hit the 80 ft-lb mark.
