How do I take this black tube off the lower? I'm trying to put on a telestock but I can't get the regular extension off? It looks like I just unscrew it but it is starting to whoop my ass.

Any suggestions?

It does just unscrew, but there might be some threadlock on it. Try heating the tube with a soldering iron, up against the reciever collar, to loosen it up.

Yea I was afraid of that. No soldering iron.. only a zippo [:(]

Are the threads left handed or right handed?

I just heated it up so much I couldn't touch the lower without a pair of gloves on and the motherfucker still won't budge AT ALL! I knew this colt piece of shit was gonna give me troubles

Standard threads, left to loosen. Also, when it starts to move, catch the buffer retainer and spring that are held by the buffer tube. [img]ar15.com/content/parts/lowerReceiver.gif[/img]

It isn't coming off.

It's got to. Keep heating gently. If you can have someone apply torque while you heat.

I wonder if it is blue or red loctite. I just read that if red loctite is put on steel then inserted into aluminum.. allow to bond.. then unscrew it will take the threads off or something like that.

I don't know about that. I had to heat mine up (Colt) to get it off and the loc-tite was all kind of white, flakey stuff. Can't remember if you could even tell what color it was.

That is what mine is.. Colt sporter.

Yup. Sporter Match HBAR. I used a propane torch and feathered all around the ring at the rear of the receiver. BTW, both parts are aluminum so go gently.

I finally got it off.. no loctite on the threads at all.

"ALL" of the screw threads on both the M16 and on the commercial AR15 are "right" hand threads. Even the "Brit's" stay with all RH threads on their U.S. spec. weapons. HTH . . . . Doug
