Cayugad, wish I could tell you what base that is, but I just don't know. It's an old one from my junk box. Don't even know where I got it and don't see any numbers on it. It's not a prefect fit to the barrel contour, but pretty close. You will probably need to take your gun with you to a gun show or gunsmith's shop and see what you can find to fit.

HuntAway, It does look a little funky to have a "scout" scope set-up on a sidehammer, but it's a good way to deal with the hammer clearance problem. The only other viable option is an offset mount which, to me,is less appealing. It doesn't look funny when you put it to your sholder and get a prefectly clear sight picture. It only works with a 1X scope (unlimited eye relief) or a pistol scope.
