My AR pistols were built from Form 4473 stripped lowers and use a naked buffer tube, no braces ever. Pistol uppers were purchased. I can just re-barrel the uppers with a 16.1" barrel, new gas block and gas tube. The only "waste" in the process in the pistol length forends and barrels. Pistol lowers will get a rifle buffer tube and Magpul stock.

I have two NFA SBRs with ATF tax stamps. They will remain as-is. There will be no "turning in" of property, just updating to remain non-NFA and ATF compliant. The sad part is I've never fired a single round out of the pistol uppers. They are NIB.

I dabbled in the AR pistol for a very short time, then just went NFA SBR. The ‘pistol’ is really not very practical with just the buffer, and the brace is really creating an SBR, so I just went the SBR route with real stocks.

Personally, I dont mind a 16” barrel, preferably a pinned 14.5” barrel. I dont want it too long for carbine work, and I dont want it too short either. The reason I went with 11.5” SBRs was to be able to put on a can and still be under 16”.

But, the short barrel cannot be stored in your house, or any place where it can be readily used.

Perhaps you should consider a $200 stamp for one of your pistols. I would, if I owned any.
