A buddy of mine from work just traded his smoker for a AR10 panther. I was in debt to him for a hot tub, so I hooked him up with a scope for it. I told him I'd install it for him. I went over to pick it up and it was stupid dirty. So I told him i'd clean it for him. Problem I ran into is it has some sort of quick detach mount for a can... and I can't get it to budge. I got down on it yesterday and just barley warped the where the wrench goes. Any ideas on getting this thing to loosen up? I have another muzzle device I can put on for him if this mount gets tore up in the process. I can't get the gas block/tube off or hand-guard with the muzzle device in the way.
