OK... got my lower and I'm ready to move forward on my FIRST and ONLY pistol build.

I have an extension tube that came from a FAKE collapsable stock, it's 11" long INCLUDING the threads.  I assume it is from some ban era rifle... it has NO holes where a tele-stock can slide and lock into place... so the capability of slapping a tele-stock on it and making an illegal SBR is not an issue.

I want to go with a 10.5" or 11.5" barrel... I'm not looking to make the shortest pistol, just the most relaible one...

1. To use this tube, I need a RIFLE BUFFER and SPRING... correct?
2.  Will this longer tube increase the odds of reliablity?
3.  Any legal issues with OAL when completed?

I figured if I won't run into legal AOL length issues and the longer tube increases the chances of reliability, why not?

Go easy... I don't know jack shit about AR pistols...

As for the legal, nothing to worry about federally regarding overall length on a handgun/pistol. It can be as short or long as you want.

IF it turns out legal 26" or more, though, you can put a vertical forward grip on it. Then it becomes a "firearm", and a "handgun" again when you take it off.

Also, whether the buffer will accept a buttstock is not the test. The test is whether you have a "useful purpose other than making an NFA firearm" for any given part among those in "close proximity" (undefined).

Thanks... that's what I got from reading the tacked threads at the top but was not sure.
