AR upper question

[Heatseeker]

I was perusing the Parts and Accessories ads in the Marketplace and saw an AR pistol upper for sale. A question was asked of the seller: Does the upper have to be installed on a pistol only lower? The response was that it had to be installed on a marked pistol lower for DROS.

My question is: Is this accurate information? I have a RRA upper marked "Pistol Only". Would I be in violation if I used this upper in a rifle configuration, even after the lower has went through the DROS process?

Thanks.

I think the issue here is going to be the length of the barrel and OAL of the firearm, not what's stamped on the upper.

If the lower was DROS'd as a long gun, it can never have a barrel of less than 16" (legal measurement) installed on it without special permits and licenses.

Thanks guys. I figured that the stamping wouldn't make a difference as long as I had sufficient barrel length, which I do(20").

Whew, that had me sweating there for a minute. I was getting ready to dismantle my baby!
