having a problem removing the butt stock of my AR

i just purchased a sling mount for my ar from daniel defense that fits it right behind the backplate, so i need to take off the butt stock/buffer tube to slip this sucker on.

problem is, holy CRAP the castle nut is REALLLLY on there. i have a little tool for it, but man, im cranking that thing as hard as i can with sweat dripping off my brow and it wont budge. in fact the tool seems to be scuffing the threading on the tube a bit.

do i just need to really lodge the receiver in a vise and crank the tool and it just finally gives?

is it possibly loc-tighted? (its a Stag model 2, btw) do i need to heat it a bit?

or is there some other issue i'm completely ignorant of?
 
I would definitely use a lower receiver vise block.
Hit the nut with some PB Blaster. You could warm it up with a hair dryer. You can also tap the handle of your wrench with a hammer to persuade it along, make sure the wrench is well engaged with the nut. Just don't mess up the receiver and everything else is not too expensive. You'll get it though
 
Some manufacturers use locktite on the castle nut. You will have to heat it to 300F to get the locktite to turn loose.
 
so if its staked on i might be SOL?

hm, i suppose i could attack a sling swivel somewhere else, but that spot just seemed perfect to me
 
You need to put the lwr in a vise block so you can apply some torque to the castle nut. If it's staked then it should have a very low torque and you just twist past the staking, I know kind of crude. If it has thread locker you well need to heat it up to just over 300*. The vise block is the key, you can't hold the lower in your lap and unscrew the castle nut.
 
Even if you are good with your hands we all have limits and this may be the time to take the gun to a local shop and let them take it apart for a few bucks and at the same time show you how this particular stock comes off so you can do it yourself in the future.
 
Warm the tube up with a heat gun or a propane torch. That should take care of the loctite if there is any. Carefull with the heat around your plastic parts. Like what they said in the above posts, you need to secure you lower with a vise block and use a good castle nut wrench.
 
I took it to my Gunsmith took him about 10 minutes and he charged me $10.00. Be careful when you take it off and put it back on because if you dont you will have springs flying around. Won't hurt you but if you lose the springs you will have to order some more. Why would you use red loctite on on an AR 15 stock?
 
i wouldnt, this is how i bought it in the store. after hearing all your advice i don't think its really locktighted on, just screwed tight and staked.

next weekend ill see what i can do
 
A staked castle nut will look like this

Make sure your armorer's wrench is fully engaged with the nut and tap on the handle of the wrench with a hammer. This poor man's impact wrench should take off a staked nut easier than if there were locktite.
