I'm zeroing at 100, the mounts not on backwards, but I did pull it back off and noticed there was a made in china sticker on the bottom of the mount towards the front (sandwiched between the mount and the rail.) I pulled it off and remounted it, got me about 5 inches back. Then i got thinking, could I shim under the back clamp between the mount and the rail, or would I screw shit up. Would really like to get some elevation back without buying another mount. If not I was thinking about maybe the leupold mk 4 mount with the 20 moa??? I guess that would remedy my problem and I could leave you guys alone.
