Was looking to pick up an M4 but Im not going to buy a tactical shotgun with a 4rd tube. Ive seen a couple M1 M2 M3s that seem to have full tubes on them are they exempt from the 922r? Keep hearing preban aswell some have pistol grips and full tubes? Can someone please explane to me if its possible to get a benelli with a full tube on it. Im about ready to give up and just get an fn slp.

Thanks
