Guys,

I've taken lots of buffer tubes off my other rifles...but I cannot get my LMT's buffer tube off. It is on there tight.

All I'm trying to do is put one of those Ace Stubby Skeleton stocks on this LMT Defender lower. It's for my son.

I have one of those mag well inserts in the lower and it's locked in my vise. Tried spraying a little WD40 in there and let it sit overnight. No good.

I don't want to do anything drastic...but how would you suggest I proceed?

Rifle tube or Carbine Collapsible stock tube?

Look close at the edges of the tube and threads, see if you can determine if Loctite was used and what color?

Take the word of someone more experienced than I, there are probably hundreds on this board, but heat is used to defeat loctite and in general gets most threads unstuck.

Rifle length buffer tube.

put the lower in a padded vice, use heat and put a wrench to the wrench flat at the butt end of the tube.......

Plumbers torches can be found at your local hardware store, usually for less than $20, get the propane one (the MAPP and other gases can burn hot enough to make easier to damage the metal).  It is a great tool to have, any stuck bolts on my cars, just fire it up and heat for 5 minutes, and the bolts come off.  Heat evenly, NOT just one spot, move the torch around the circumference as you heat to get evenly heated.  Try to concentrate the heat on the receiver portion, avoiding the tube, you want the receiver to expand more than the tube.

It it is lots of loctite that is your problem, then you probably want to get the threads as hot as possible without doing damage, to burn out and weaken the loctite, heat tube and receiver well and even, let it cool then heat up just the receiver portion to get it to expand more than the tube.

Guys,

Thanks for all of the replies.

The damn thing popped free last night.

Was it loctited?

I saw no residue of any kind.
