Saw an ad for an H&R M12 scope mount. Ad states it's the mount once made by Ken Viani! Company is scopemounts.com. I didn't see the mount on the website but the ad states to email them at comments@scopemount.com, nicole_skscopemounts@yahoo.com or call at 800-578-9862. I have no affiliation with the company so can't comment on quality, but I do have the original made by Ken Viani and its very nice. Its an extended rail so prone/sling shooters can mount the scope farther forward. The mount also accepts iron sights (not many of us iron sight shooters left LOL) so you can switch from scope to irons without changing the mount.
