Same as the SRH+ but requires the removal of the rear sight. We use the rear sight notch as the recoil lug, as we do on most of our scope mounts. This mount is a more economical solution to the scope mounting issues on the large caliber's. This is a very attractive solution to the problem. This mount will also fit the .44 MSR for your extreme recoil reloads. Accepts all Weaver style rings and accessories and most Picatinny rings and accessories.
