You mean a AR pistol, right? Or MP5 etc? Your Govt is AFU ( All Fouled Up). Build an AR pistol with a 7" barrel with a "Brace"and don't worry about it. Here's the first thing that Googled for AR pistol.

It can be a rifle,
Or it can be a pistol,
But both it cannot be.
Once it is one,
It cannot be the other,
Unless you wish to swing from a tree.
(And get your dog shot.)
Assuming this isn't an ATF troll, yes, an SBR requires a tax stamp.
Yes, you can build an AR pistol and use shorter than 16" barrels, but you have to use specific "pistol" butt stocks, not regular rifle stocks.
An AR lower receiver can be purchased and assembled as either a rifle or a pistol. Once it is mated to an upper receiver, that lower is forever whichever one you decided, rifle or pistol.
Best advice is if you are going to messing around with short barrels, make darn sure you understand the rules and regulations, don't just go asking questions on the internet.
Yes, you are constructing an illegal SBR, which is a felony. Unless of course you mean you put the rifle forend on the charger, which i'm absolutely sure you meant, which is perfectly fine.I have a Ruger Charger pistol and a Ruger Takedown rifle - the front section (barrel and forestock are easily interchanged. So, everytime I switch them I'm breaking the law? Never saw the need to do so, but had to try them out.
That’s the thing Court costs and time. I’m not saying just saying.Just got reading the summary. As mentioned above by ryahn487 the defendant didn't have prior approval for his cheek rest, but the was found not guilty anyway so all is moot (except his court costs and time)
You will need to have the receiver engraved with certain information and to certain specifications.
what information is supposed to be engraved in the receiver?
