Is it possible to buy an AR15 reciever, import a 50bmg bolt action upper and have it non-restricted?
I ask this because the AR18 uses the same FCG as the AR, but its non-restriction resides in the fact that the upper is a different system than the AR15.
Given this as the case if you built one from scratch with a 16" 50BMG single shot upper, would it still be restricted?
