AR pistol question

[huntandjeep]

Do you guys with AR pistols ever run into problems with Leo officers while out with them  ? Thinking about building  a 10.5" with the intent of SBRing it. Plan is a BCM lower with SB Tactical PDW  brace , Aero ( or Noveske) upper , 10.5 barrel , 12" rail , with either Aimpoint Pro or Acog

I have a Sig MCX pistol and I've never had any problems.  I don't shoot a lot at public ranges but when I have, with this particular gun, it seems everyone assumes it's an SBR.  Some folks get all uptight and want to debate whether these are pistols or not and it's generally not worth discussing so I just let them think whatever they want and go about my day.

That's what I'm worried about , to many people thinking they know it all , when in actuality they know nothing . Mine is mostly going to be my Jeep gun,  hide behind the door gun.

In my experience, the people who try to cause a problem are ignorant gun owners who think they know everything, mostly the Fudd type who think you're an idiot for having any sort of semi-auto. Personally I've never had any trouble from law enforcement about AR pistols. They are commonplace enough now that it's just no big deal.

Haven't had it out yet but I've already had people ask me if its legal and how long did my SBR paperwork take.

Personally I wouldn't bother with the SBR paperwork with if you are already doing a brace. there's really no point anymore. plus remember this is a "pistol" so you can keep it loaded in a vehicle and is good in most states VS a SBR is not legal in some states and is considered a rifle. keeping a rifle loaded in a vehicle is illegal. so pistol the F out of it!

I have been following your progress in your thread 
Actually the only reason I would SBR it is for a real stock. Although once I get the PDW brace my mind could change.

I hear ya, but the paperwork and registration just makes it not worth it imo. Plus like i said i can drive with mine loaded, which is why i built a "pdw". I wanted a travel rifle lol.

What’s the difference between these and an actual short barreled rifle? Honest question. I’m a dummy when it comes to AR’s. If you showed me either one of those and asked what they were I would have said SBR.

Quick answer is overall length and presence or absence of a shoulder-able buttstock.

still a pistol

and how the lower was originally registered, you can't "reuse" a lower that was previously used as a rifle.

OK, that's what I figured, but both of them in the pics looks like they have shoulder-able stocks.  Threw me off.

Also, if you like to use a vertical foregrip those are a no-no on a pistol. 
Angled foregrips like the magpul one are ok, vertical one are not.

If your overall length is over 26" a vertical foregrip is legal , under 26" you need angled

It's a tricky loophole that required some review by the BATFE. The design of the brace and the real world application of it don't always match up, but the ATF decided to allow it.

I've know a few people who had them and they all built the pistol around the brace design with the intent of using it a certain way. Think of this, I can buy a 5# pipe wrench and use it as it was intended, or I can use that pipe wrench as a hammer. Either way it's still a pipe wrench, even if I've never used it on a pipe. In this case, it seems like the pistol braces just make a great "hammer".

That's a great analogy.

As for any difference in the gun - other than the legalities of a fore grip, the only difference between an AR pistol and SBR is the presence of a stock. Functionally they are identical, all internal parts are the same, etc.
