Hi, guys. This is my first time posting, so please be gentle.
I have a Bushmaster ORC that I'm trying to put a new sling adapter (this guy) on. I'm trying to get the extension nut off the stock and having some issues. I put my trusty AR-15 multitool on the thing and tried to hand-crank it off, but it wouldn't budge. I put it in the bench vise and tried it again. It started to move a bit, but, when I looked at the nut, I noticed that the slot on the nut was stripped out, so all my moving was just my destroying the thing.  I did some other stuff just to get it to move, including wielding the padded impact tool, but nothing is helping. At this point, I just have a nut with lots of scratches and loose metal on it.
Does anyone have any recommendations on getting it off other than taking it someone who knows what he's doing? Since mine's pretty much destroyed, I'll need a new nut. Are all created equal? Thanks for any help. –– Aaron |

I would use a MAPP gas torch and heat the nut up. Not red hot but hot enough for the metal to expand and loosen up some. It will also break any loc-tite bond if they used that...
Bravo Co is a good place to get things like castle nuts and end plates from..... 
Oh yeah and since the nut is fubar you can use a set of vice grips.... |

Thanks Belmont31R. I took it to the local AR15 guru, and he started relating a story of how he (a 350lbs dude!) had a 4' crowbar on his Bushmaster trying to get the extensioni nut off. I believe he said something like "Loc-tite sucks" or something.
He's going to torch it and replace everything for me. Thanks again!

You can also use the tip of a soldiering gun on the head of screws and let the screw heat up that way. You should see a small puff of smoke when the bond is broken....

. A little heat will soften it up enough to get it off.
