Yes, the guard was stuck to the nut; it was a Clark Custom hand guard. I cut it off just past the end of the nut. (If I feel like it I can get another nut and reuse it) It was epoxied to the nut, and the gas tube was what was keeping it from spinning( kinda obvious). I pulled the gas block and tube off and the nut was basically free spinning, easily spun off with just fingertip pressure. Now, the barrel was seated into the receiver pretty tight. At first I thought I may have to apply some heat to get it out, but a couple taps with a rubber mallet and it reluctantly came out. I can reuse everything but the nut it looks like, but I don’t have any intentions of going with another hand guard that requires an epoxy stuck barrel nut. I dropped the barrel off for threading last night and as soon as that’s done will put it on the lefty upper and try to see what I really have. Thanks for the input from everyone.
