The process involves using a tapered barrel section as a tool to slightly open the bayonet's muzzle ring, ensuring a snug yet easily removable fit. The video also touches on the historical context of Mosin bayonets being sighted in with the rifle.

Quick Summary

To fit a Mosin Nagant M91/30 bayonet that's too tight, use a tapered barrel section as a tool. Clamp the bayonet in a vise, then drive the tapered barrel into the bayonet's muzzle ring. This slightly expands the ring, allowing the bayonet to slide on and off the rifle easily and seat flush against the sight base.
