Frequently Asked Questions

What are the key identifiers for a Mosin Nagant 1891/59 carbine?

Look for the '1891/59' marking on the receiver. The rear sight base should be milled to remove long-range markings, and it typically lacks a bayonet lug, similar to the M38.

How can I identify the arsenal and origin of a Mosin Nagant 1891/59?

Check the receiver for arsenal stamps like Izhevsk's hammer and sickle or arrow in a triangle. Many 1891/59s show two dates: original manufacture and a later re-arsenal date, often indicating Bulgarian service.

What is a 'counterbored' muzzle on a Mosin Nagant?

A counterbored muzzle means the rifling has been intentionally drilled out at the very end of the barrel. This was a common practice on surplus rifles to restore accuracy on barrels with worn muzzle crowns.

What should I look for regarding serial numbers on a Mosin Nagant 1891/59?

Ensure serial numbers match on the receiver, bolt, magazine floorplate, and buttplate. Be aware of 'force matching,' where original numbers are struck out and new ones are stamped or electro-penciled.
