Question: Can I put this in my 12 gauge shotgun?
Answer: As long as it has a rail. It seems well-built enough to handle the recoil of a 12g.

Question: Can the clamps be adjusted so it clamps to the rail better. I noticed that one clamp has more distance between the rail and clamp.
Answer: Of course, release the lever, press the cross bolt the shoulders of the nut will slip outside the hex box of the mount. Then simply tighten/losen as needed on each end.
