Proper torque of AR barrel nut



Here is how to get the proper torque value when using a adapter like an AR Armor wrench. 30-80 ft/lbs is what I have heard. Aeroshell 33MS for grease. 40 ft/lbs for castle nut. Thank you 2phast.I posted a video explaining the formula at https://youtu.be/DA1iw7mklo0
