Well, I don't know. I pick up a lot of ~~junk~~, ah, good stuff, at garage sales, and I think this was in a box-o-stuff. It is .010" thick after removing the backer, 3/4" wide, black in color and absolutely no markings at all. I think it is similar to 7746A31, which can be found at http://www.mcmaster.com/#. Copy & paste 7746A31 into their search field and click find.
Hope that helps,
TM

oh cool, thank you very much! was considering this CS Hyde Teflon Mouse Tape from amazon before you responded.

That would probably work fine - but I didn't see a thickness. I think I had to stack a few pieces of the .010" stuff to get it the way I wanted it. Good luck & let us know how it works out!

alright, i went ahead and ordered the teflon mouse tape since it's less expensive than the mcmaster antistatic UHMW polyethylene tape. (amazon prime shipping too, heh). i'll try it out and report back. perhaps it'll be a great solution for the budget-minded.

the teflon mouse tape works great! i have no way of measuring the thickness of it but it looks pretty thin. thin enough for it to be translucent when working in a well-lit room. i went ahead and placed two layers (long strips) of the tape on the inside of the stock at the 12 o'clock, 3 o'clock, and 9 o'clock positions. did a test fit and noticed there was still a little play coming from the bottom channel of the stock, where the retention pin locks the stock into the 4 positions of the tube. so i went ahead and placed one layer of teflon tape just to the sidewall of the lower channel of the stock (to avoid messing with the retention pin), and did another test fit. worked great! absolutely no left-right wobble and slides really smooth. there is still a little front-back wobble, probably due to a small gap where the retention pin locks into the tube... but i'm ok with that.

over all, VERY pleased with this inexpensive fix for the stock collapsible stock. this will hold me over for awhile before getting a magpul. haha

thanks, again, for your help and suggestions, TM! time to go shoot.
