John Myer at Custom Gunsmithing (540) 837-2598 in Boyce made mine. Should not be hard for any gunsmith to do if you are talking about a mounting rail. Will need the mounts and what click adjustment do you want (1/2, 1/4 or 1/8) to set the spacing for the mounts.
sscoyote The BV20 is hard to beat for a long range hunting scope. The field of view is extra large, optics are great. Reticle is always centered, you can use it for as far as you want to shoot w/o running out of adjustment--you can shim bases for elevation and never bind the scope, you can make the adjustment 1/4 moa or 1/4 inch (which is a lot better for long range hunting) simply by changing the base separation. The adjustments read like a micrometer. It's superb even if you don't have a lighted reticle - make sure you read exactly how to make parallax adjustment--do not overturn.
