Upper Swap

Exploring options in case DC comes out against the pistol brace and moves them into the SBR arena. Has anyone ordered the 16" PSA GEN4 UPPER with charging handle/BGC and dropped it onto the PSA AR-V 10.5"? Did it require any modifications and did the LRBHO still function?

Please keep the topic on build options and not the politics of pistol braces.

My understanding is that AR-V uppers and lowers only work with other AR-Vs.

Completely different receiver and bolt profile, won’t fit.

I thought the same thing but when I talked to CS about barrel swaps they suggested using the Gen4 upper kit. The rep couldn’t tell me if the swap was seamless. Afraid to spend $500 on the upper kit only to find out they don’t mesh well together.
Next option might be to just swap the barrel out.

I hate being the clueless new guy.

That is not true, you would have a long barreled pistol. The opposite is true where if you were to convert a lower that was sold as a complete rifle into a pistol it would be an SBR. The ATF considers any receiver sold as a rifle to always be a rifle, even if you put a short barrel and brace on it.

How was the Receiver registered on the 4473 at the time of the purchase?
