It is for a remington.
Something to turkey hunt with.
It has to be hevishot capatable.

I have some I dont use let me look and let you know -

I use an "Undertaker" Made by H.S. Strutt, In my Browning Gold Fusion. I'm putting Remington no.53 inch turkey loads through it and I'm darned happy with it! I've bagged 4 Toms in as many years.

I use a Remington Ext. Full extended choke in mine. Make sure you get the one that says Lead and Hevishot on it, and it'll be just fine.

EDIT: Brain fart. I just realized you were looking for somebody selling one rather than a recommendation.

I have a new Rem Choke SF super full ckoke in box. 20.00 plus shipping
