This video details the advanced installation of the Rock Solid M-24 rail on a Mosin Nagant rifle. It emphasizes precise alignment using laser leveling and milling techniques to overcome common receiver cant issues. The process includes drilling and tapping the receiver, securing the mount with screws and a cross-pin, and using epoxy bedding for a permanent, rigid fit.

Quick Summary

The Rock Solid M-24 rail mounts on a Mosin Nagant using points on the receiver top, stripper clip guide, and rear sight base. Precise alignment is crucial due to potential receiver cant; use laser leveling and a bore sighter to ensure parallelism. Milling the front pad and drilling/tapping receiver holes are key steps, followed by epoxy bedding and torquing screws to 35 inch-pounds for a permanent fit.

Frequently Asked Questions

What are the key mounting points for the Rock Solid M-24 rail on a Mosin Nagant?

The Rock Solid M-24 rail mounts using two points on the receiver's top flat, one through the stripper clip guide slot, and a forward segment that fits into the rear sight base, ensuring a secure and stable platform for optics.

How do you ensure the scope mount is parallel to the bore on a Mosin Nagant?

Precise alignment is achieved by using a bore sighter in the barrel and a magnetic laser level on the rail. Measurements are taken over a long distance to make incremental adjustments with the mount's jack screw until perfect parallelism is confirmed.

What common issues arise when installing a scope mount on a Mosin Nagant?

A frequent problem is the rear sight base not being perfectly aligned with the receiver's flat bottom. This requires careful checking and often milling the mount's front pad to ensure the rail sits parallel to the bore axis.

What is the recommended torque for the Rock Solid M-24 scope mount screws?

The screws for the Rock Solid M-24 scope mount should be torqued to 35 inch-pounds. This ensures a secure fit without over-stressing the receiver or the screws themselves.
