Gunsmithing pinning a scope rail

Re: pinning a scope rail

Are you wanting to do it at home or hire it done? Depending on your skills and comfort level installing the pin or pins can be installed at home, but it's not a beginner project. Assuming the original base was correctli installed making a different base fit will not be difficult for an experienced gunsmith, machinest or tool and die maker. If not correctly installed all bets are off.

Why would you want to pin the base and then change it?

Best of luck and be safe.

I don't have the skills or equipment (that's in part why I didn't really know). I could see how if you screwed in a rail it would be easy to cut a hole through the rail and into the receiver top. I wouldn't plan on changing it, but was just wondering if for some reason I did, would it be difficult for a smith to do it. Don't see much discussion about this topic, even though I know of a few people who have added these, and perhaps at least one custom receiver maker who offers this as an option. Seems to be a simple solution to problems with any loosening of a rail.

The pin doesn't stop the mount from coming loose. Loctite on the threads of the fasteners does that. The point of the pin is to take the shear load off of the screws during recoil if the base doesn't have a recoil lug machined on it, and to absorb any shear load from other directions if the rifle is dropped. Many of the aftermarket rails have a recoil lug machined into them.

I would just fit larger diameter screws . Drilling and retapping the existing holes is easier than fitting a recoil pin. Once it is loctited in it is way stronger.
