-edit- it's a stupid question really... just wanting to see what opinions are floating around. pros, cons, anybody who has done it... etc.
 
the attachment in mind at this moment, would be a fake suppressor.

it would not be an SBR. as that would be illegal without the paperwork. it would just be an illusion.
 
i'm just wondering if it would be a cheap way to attach a stock to your PLR-16. the permanent attachment/suppressor would add extra barrel length (in theory) putting it over the legal 16" barrel length.
 
law states that you can turn a pistol into a rifle, via this... however the opposite is illegal (turning a rifle into a pistol)... because once it has been originally manufactured with a stock, it must always be a rifle. however, as being a pistol, it can go back and forth between pistol and rifle... just depending on legal barrel and overall lengths.
 
back to the original post... i asked the question to see what opinions people have. if it has been done or not, etc.

I was under the impression that a pistol regardless of barrel length needs an SBR stamp to be turned into a rifle.

Fiveseven is right, as is Midiwall. Logically, the OP is correct. However, we're dealing with ATF and logic does NOT apply.
 
Any PLR-16 was made from the factory and registered with ATF as a pistol. If (for whatever reason) the serial number is run, and it has a shoulder stock on it (regardless of length of barrel), you better have a tax stamp, or else you're going to club Fed.
 
It is just as simple as that. Once a pistol, ALWAYS a pistol, and NFA will ALWAYS apply. Same thing with conversion to SBR status. Once titled and converted into a Title 2 weapon, then it shall always be one. Even if you were to remove the shoulder stock, you would still need to keep the papers with the gun, proving you had something legal.
 
Sorry.
