You can buy mounts fron several places for your Rem. I had a Mossberg 500 that i could kill clay pigeons with at about 70-80yds. I was using an 18" smoothbore with iron sights. As for CVA, they have come a long way over the years. I had a .45cal Kentucky rifle from them my dad bought, as a kit 20 some years ago. It wouldn't shoot for nothing, maybe three inch groups. I lopped the barrel off to 22" and now i get 1.5" or better. Who knows???? I also have one of there inlines, it shoots as good as my brothers Encore. I paid less than 150 bucks new too.
