So is it 1/7 or 1/8? The title and specs don't match.
B R on Nov 13, 2018
BEST ANSWER: Looks like they fixed it - 1:7! Great for supes and subs!
Is a special,permit required prior to purchase or to own the gun?
Bob B on Oct 25, 2018
BEST ANSWER: You can purchase this upper without any paperwork as it is just an upper. IF you mount the upper on a rifle lower then you have created an SBR (Short Barrel Rifle) which requires an NFA stamp. If you mount it on a pistol lower, then no permit is required.
Is this already put together?
Adam B on Nov 10, 2018
BEST ANSWER: The upper is assembled as shown and ready to pin to your pistol or SBR designated lower.
Is this a threaded barrel?
