has anyone seen a rifled choke or a ported improved cylinder. i dont know the thread specs but i love this little pump gun and want to make it a year round gun for deer and birds.

About all I've ever found for my Mossberg 500 20ga is full, modified, Imp Cylinder, & Skeet chokes. There are not a lot of options for the 20 ga. []

I've seen ported riffled barrels for your gun

i know i can get a rifled barrel for it but im getting great results to 50 yards with the smooth barrel and scope. i dont think i will be shootin much farther than that. it does kick pretty hard with the slugs. maybe i will call up some of the choke manufacters.
