How do I remove the blast diffuser off the end? I can’t seem to get it off there without the barrel turning. It seems like it has loctite on it. — 2 Answers

a standard AR armorers wrench should have the necessary wrench to remove this as that's what I used. you could also just use a crescent wrench and back it off because mine was just barely hand tight
