So to lock this down without LockTite you are talking over 70foot-pounds of torque on the barrel nut. That can be hard on the receivers. As a solution that seems to work quite well was to bed the barrel and gas block in the LockTite 2440 (replaced with 243) and torque to normal specs."
I thought Bill A. was on crack when he first said that, but when I pulled my gas block to install a free float it happened to me just like he said it would. I can personally testify to vertical stringing in my 19.5" upper until I bedded it. At 600 yards it looked like a ladder. Bedded it with blue loctite and it disappeared. After that I listened closely to anything Bill had to say!!!
