AR15 pistol lower??

[Holland&Holland]

I will let others smarter than I give you full direction but, yes, if you install a stock and a shorter than 16 inch barrel, you better have a tax stamp in possession as you just built an SBR regardless of what it was recorded as in its first sale.

Or install a shockwave blade or sig brace. Just don't get caught shouldering it.

Those are not stocks.

There is no registration.

Not for a pistol or >16" rifle but it would need to be added to the NFA registry to be an SBR.

He stated very clearly he has no intention of SBR so unless his virgin lower is not as represented then it is not registered, there is no registration currently.

I was just clarifying that there is registration in the case of an SBR, I don't care what his intentions are. It's kind of important.

I understand that. It is also important to dispel the myth that when you complete a 4473 you are "registering" a firearm As it is a lower that has not been built into anything at this point, it is not registered. Yes if he builds an SBR he does need to register that but that is not this situation.

I bought a lower that is registered as a pistol, the guy said it can be used as a rifle or pistol if I want to make a rifle. Is this true? From what I read at the ATF sight is that this subject is very grey. It looks like I can make it a rifle if I use a 16 inch long barrel and a rifle but stock. But if I use a shorter barrel and a rifle stock it has to be registered as a SBR.

Any one know the law on this?

Yes, a short barrel (less than 16 inches) and rifle stock is an SBR and absolutely needs to be registered!

The guy would've have been better off telling you to keep pistol lowers as pistols with pistol buffer tubes and get a regular rifle lower for building a rifle with a regular carbine/rifle buffer tube. This is a can of worms that this gun store guy is opening and spreading around and he should have his mouth slapped. Anything to make a sale I guess.

It is true that pistols can become rifles as long as they meet 922r requirements and minimum barrel and overall length requirements. I have typically heard of people doing this sort of thing with HK MP5 pistol clones, where you add 922r parts and a 16 inch barrel. Pistols don't fall under 922r, but rifles do and you are turning a pistol into a rifle so 922r comes into play. The problem with turning a pistol into a rifle is that AFAIK legally you cannot turn it back into pistol. Much in the same way when a firearm becomes a machine gun, it can never be anything other than a machine gun legally from that point forward. This is honestly a can of worms this guy is toying with. I'm sure he's already got people swapping out the buffer tubes on pistol lowers for regular carbine tubes and thinking it's okay with the short barrel still installed and then swapping buffer tubes and barrels out like candy constantly.

I'll state again this guy should be saying Pistol lowers for pistols and Rifle lowers for rifles, and nothing else.
