10.5" Vs. 8.5" Barrel On AR Pistol

I believe your referring to this. http://forum.pafoa.org/showthread.php?t=26889

Thanks. Not the thread, but I realized now that it was XringShooter who posted a lengthy and thorough explanation fairly recently.
I'm sure I could find it by looking into his recent posts.

It was the reason I went ahead and built my pistol using the stripped lower (new/never assembled into anything) I had in my hands rather than going and buying one that was specifically a "pistol lower".
I was mistaken in my thinking that it had to be a "pistol lower".

I only found that thread recently as im am planning my own pistol build while following yours

Went 8.5" because it was what was available at the time and due to price constraints.

Interesting topic.

For some time now, I've thought about acquiring an AR15 pistol upper for matching with a DPMS lower group that's been tucked away for a long time. First off, the DPMS lower receiver is marked with the "K" for "kit" designation. To my limited understanding, it would be legal to use that particular lower group for an AR pistol build. Is this correct?

Second question is . . . . though the DPMS "K" receiver has NOT been employed as part of a rifle, there is a long buffer tube already mounted. Would it be legally and functionally okay to use that rifle tube having long spring without stock for a 10.5-inch barrel length pistol. It is assumed too that AR pistols use a standard type bolt carrier group.

Thanks in advance for info . . .

The language as I recall suggests you'll have an issue if a stock can be readily attached. I assume a rifle buffer will readily permit a stock to be attached. Constructive possession, blah blah blah...

IANAL

I've never heard of a "kit" designation and can't imagine how it would have any bearing on whether it's used for a rifle or a pistol.

The buffer tube will need to be a pistol buffer tube. They are shaped so a stock will not slide on.

BCG is the same in either.

Heard about this long ago . . . somewhere . . ? As it went . . . It was not legal to use a common AR rifle lower assembly to make an AR15 shorter than 16" barrel pistol. Regular AR15 lower receivers used to fabricate rifles were for long arms only. For AR15 pistols / handguns, only "kit" or "K" (before serial #) designated lower receivers could be used. The "K" kit marked receivers can be employed with both pistols and rifles. Once put on a rifle however, that K receiver can not "legally" be used again on a long arm. At least that what was my understanding via some anal retentive type information.

Yeah, I think you have some factual info mixed in with some legal nonsense that was straightened out several years back.

The state police tried making their own laws, but that was "fixed" a while ago.
A lower is a lower. It's not a "pistol lower" or "rifle lower" - it's just a lower.
