1) Pistol lower has to start out as a pistol(you can not convert an AR rifle into a pistol).I'm several years out of the AR game, and completely new to AR pistols. Am I correct in understanding that a pistol in the ATF/MD sense can essentially be an AR (HBAR not needed, right?) that doesn't have a "stock" but either an enclosed buffer tube or a fancy brace of some sort? Essentially, I could put a 11.5" pinned/welded upper on a lower that was never a rifle, slap the right tube/brace on its backside and be off to the awkward "pistol" races?
I know a MD legal AR has to comply with the 29" OAL, but a pistol has a separate minimum? This shit is wildly confusing, and I was once fairly well versed in it.
2) You can put any length and profile barrel you want on it. No need for pin and welding.
3) You can use any type of buffer tube you want. It can be a plain pistol buffer tube or it can be an adjustable carbine type buffer tube.
4) There are no minimum length requirements on AR pistols(they are not SBRs), they can be as short as you want.
