Well the part number above is a definite no go. The gas piston is much smaller. After a very informative conversation with an incredible customer rep it appears that the 1301 Tactical is kind of a stand alone platform. A bummer as I was hoping that I could use the 1301 for a few other purposes.. There's no loosing here as I still have a great shotgun and maybe next year I'll grab a competition to fill the void.
Shoot straight!
