all i need is the lower for this ?
leonard c on Jul 15, 2018
BEST ANSWER: Yes, make sure you have a stabilizing brace on it, as it will fall into Sort Barrel Rifle (SBR) by the ATF. If you own or construct an SBR you have to apply (Before building or owning) for a tax stamp. If you use the Stabilizing Brace, you will have to register as a pistol and the 10.5 inch barrel will have to remain a pistol. I love it. It's small and mean!

So as long as you build a pistol this would be legal to buy and install? No nfa papers?
Jason W on Jul 4, 2018

I own 2 of them and love them.
I am in love with this pistol upper. I buy these uppers with A2 front sights because the gas block is pinned in place which is the start of a duty grade rifle.
