Can anyone help me determine what frame my barrel fits? It started life as a 22 REMINGTON JET but it has been re-chambered to a 225 WINCHESTER. It is 22" long with a ramp front sight and a fold down rear sight. On the left under side of the barrel just above the lug it is stamped with the number 7410. It has the old snap on forearm. I have tried it on several SB1 & SB2 frames but it will not close all the way. I do not have an old shotgun frame to try it on. Any ideas? I picked it up some where cheap because I love the caliber.
Thanks LONGTOM
