Halcon, I didn't know if it was a PolyChoke or not. That's why I said orsimilar. I didn't know Mossberg had their own adjustable chokes.. It just came to me.I faintly remember back when I worked at the gun shop we had Mossbergs with that choke on them.I believe they were on the 500's.I don't think they had as much adjustment as the old Poly Chokes.I have a Rem 870 bbl with a Poly Choke Deluxe. I think it was call Deluxe. It was the better of the Polychokes.I had that one installed.. I never cared for it.. I wouldn't buy another one .
