870 slug gun

[mrmiskin]

I have a 12 gauge that I got from my father with an extra rifled barrel. The mount for the scope is cantilevered and it is a dove tail rail. Having trouble with scopes and mounts. The regular scopes like a 3x9x40 are not up high enough to zero it and I am having trouble finding anything that fits the dovetail rail. I have seen the BSquare mount you can use by removing the pins in the gun but was wondering if there any more suggestions. Thanks
