Smyth Busters: AR-15 Barrel Nut Torque
This video from Brownells Gun Techs debunks the myth of precise AR-15 barrel nut torque settings. They explain that the wide mil-spec range (30-85 ft.-lbs) is due to the gas tube clearance requirement on original M16-style barrel nuts. As long as the gas tube can pass and the torque is within this broad range, accuracy is not compromised. They advise users to adhere to specific manufacturer recommendations when applicable and encourage viewers to suggest future firearm myths for debunking.
