No theres no loctite on there.




I know its not technically the correct way but if it were me Id just hold it between my legs, and take a 3/4" open ended wrench to it. Its not something Id do on the same upper repeatedly as you can wear out the notch in the upper or break the pin on the barrel but Ive never had an issue with the "between the legs" method, and I don't really recall anyone having an issue, either. The barrel nut holds the upper and barrel together tighter than what tq is on the muzzle device.
