Extremely solid - JP Enterprises 45 Degree Offset Adaptor

I needed two of these to mount a rifle scope. The rifle was drilled and tapped for an old Weaver side mount that put a modern scope too far aft. I replaced the base with a Picatinny rail. The first attempt at scope rings was two cheesy flashlight mounts, and they loosened under recoil. This 45 degree adapter has square recoil lugs that engage the rail slots. Each adapter has two lugs and two clamping screws. It’s not going anywhere. The recoil lugs are a bit short and centered on the rail. I would avoid using a Picatinny rail with an aggressive relief slot down the center. The geometry of the offset put my scope very close to directly over the center of the bore.
