Does not fit - Strike Industries Beretta 1301 Tactical /A300 Ultima Patrol Strike Shotgun Barrel Clamp

you would think with this being a new product, it would be compatible with the new a300/1301 mag tubes, but it is not. the new mag tubes have too short of a cut for the longer body of this clamp, and will not fit anywhere. i think this would have worked fine if they just tapered the sides a bit, but I'm not about to take a dremel to this thing
