Guy is in violation ^^^
Having a vfg on that pistol is now a AOW. I can't believe they would publish that.
Not necessarily, though personally I'd want an ATF ruling in hand for my particular configuration rather than assuming. From the article:
If you are thinking about building an AR Pistol, you first need to start with a lower that was registered to you by your FFL as ?other?. You cannot take an AR-15 that started life as a rifle and turn it into a pistol, but you can take an AR-15 lower that was registered as OTHER, build a pistol, convert it to a rifle later, then back to a pistol. Clear as mud? If you?re doubtful at all consult a legal expert in your state. We live in a time where even legislators and LEOs can be confused by poorly worded, ambiguous, sometimes contradictory laws. Make sure you know what?s legal and what?s not.
It is also my understanding that if the total length of the firearm is over 26?, then you are permitted to add a vertical grip without the need for an NFA stamp because it is not an AOW. Again, check that one out for yourself.
Here's an ATF letter regarding a 26 1/4" Tommy gun that backs up that guys position:
http://www.franklinarmory.com/XO-26_Letter__c_.pdfIn your letter, you state that your company's [...] pistol has an overall length of 26.3 inches and a barrel length of 10 1/2 inches. The addition of a vertical fore grip to [the firearm in question] would result in this firearm no longer qualifying as a "handgun" or a "pistol" as explained above; however, it would not be subject to NFA/AOW classification provided its overall length is at least 26" and it is not actually concealed on the person.
NFA's definition of a SBR:
"Short-barreled rifle.
A rifle having one or more barrels less than 16 inches in length, and any weapon
made from a rifle, whether by alteration, modification, or otherwise, if such weapon, as modified,
has an overall length of less than 26 inches."
--This is why you have to start w/ pistol lowers in the AR building of these for instance.
--And overall length federally for the ATF is with the stock fully extended, at its maximum length.
So what the letter and ruling is saying is that if the barrel length is less than 16" and the overall length is less than 26" then it is an SBR. If barrel length is less than 16" and overall length is more than 26" then it is a "firearm" not falling under NFA regulation. If you conceal that pistol w/ foregrip though, then you're for all intents "converting" it to an SBR and in violation of the NFA...
And "pistols" and/or generic/limbo "firerarms" still can't have a stock, else they become "rifles." And rifles must have a 16+" barrel or be registered as SBRs.
Here's the ATF definition of a firearm:
Firearm. (a) A shotgun having a barrel or barrels of less than 18 inches in length; (b) a weapon made from a shotgun if such weapon as modified has an overall length of less than 26 inches or a barrel or barrels of less than 18 inches in length; (c) a rifle having a barrel or barrels of less than 16 inches in length; (d) a weapon made from a rifle if such weapon as modified has an overall length of less than 26 inches or a barrel or barrels of less than 16 inches in length.?
And non-NFA weapons generally fall into 5 classes:
1.
Rifle, has a buttstock, needs a minimum 16" barrel length, needs a minimum overall length of at least 26", and less than 0.6" bore diameter.
2.
Shotgun, has a buttstock originally installed, needs a minimum of 18" barrel length, needs a minimum of 26" overall length in its firing configuration, and needs a bore diameter of less than 1".
3.
Pistol, no stock, to be fired with one hand, barrel less than 16", overall length of less than 26", and no vertical foregrips.
4.
Firearm -- this is the limbo category most often forgotten/ignored -- no stock, barrel less than 16" (pistol/rifle) or 18" (shotgun), and overall length greater than 26" -- shotguns not falling into legal definitions w/o every having stocks attached and pistols with vfgs and similar prohibitions for pistols definition legally defined
5.
Pyrotechnic flare guns and the like with bores over 1" but having low enough muzzle velocity to not be NFA.
EDIT: Here's another ATF letter on 26"+ OAL and VFG -- this is probably the one you want to have on your person if modding the weapon for a VFG and taking to public ranges:
