I dont want to get answers about different guns because this guns flash hider is custom and not like other guns. The flash hider has a little hole where the outer barrels threading is but nothing seems to be inside that hole its just empty. I left the flash hider in hot water for around 3 min and took it out than quickly twisted it counter clockwise but nothing seemed to work(i also tried clockwise). I than tried the hair dryer trick a couple of times and i used the hair dryer for around 12 to 13 min. I tried to twist it off again and it didnt budge one bit. i found out about some kind of very strong super glue called loctite and to looses the glue it needs heat but ive already applied A LOT of heat. I really need an experts help!
