Gen 1 LR-308...staked buffer tube? How do I remove it?

[Token]

I have a lovely Luth-AR rifle stock, rifle length buffer tube and parts ready to go.  However when I go to remove the old buffer tube from the lower receiver...it won't budge.  It appears to be staked [little indents on the receiver side of the lock nut] so how the heck do I get it off?  Is it just a matter of brute strength, or is there a trick to it?

TIA for any info or suggestions...

Brute strength is one option.  Carefully filing away at the staking deformations is another.  Very carefully grinding away at the deformations with a Dremel/pencil grinder is another.

Are you planning on reusing the shorty receiver extension?

The ones I've done....I just made sure the lower was secure and I had a good grip on the castle nut....and cracked that beast with a heavy rubber mallet. Popped right off.

Nope...not planning to reuse the carbine buffer tube.  I will acquire a larger hammer...

Force it. Break out the BFH if needed. 

If you don't know what you're doing, a dremmel will completely FUQ your situation up.

If you are dremmel savvy, have at it. It's a lot easier than you think.

Yes you did!

You big hammer guys are reminding me of a dude pulling apart a lathe, and a part won't budge.  He says "Let me get a bigger hammer real fast."  Sure enough, he snapped that cast iron no problem.

Yes you will snap cast iron with a sever blow from a BFH. That was the only way to demo a cast iron tube for removal. Safety glasses were a must as the porcelain shatter's like glass. That was a real PITA.

Gentlemen [and ladies, if any]:  The hammer and punch method worked for me.  I clamped the old buffer tube in my vise and used an old nail set and my big hammer [and a shot of WD-40] and the castle nut came off with minimal effort and practically no damage to the old parts. They will be reusable if I ever need them.

The Luth-AR stock looks great on my LR-308...I'll post some pictures in the fullness of time...

Thank you all for your kind advice.  I am still an AR tyro, but I'll get there someday.

Glad it worked out for ya brother. Don't sweat the little $hit.
