What's one worth? Condition new w/ sheath. It's a "weird" one. (Those are my words) Small handle with wood scales, has a push button near the tang to release the two locking teeth that move vertically vs. horizontal. The blade is similar to the Russian SKS blade bayonet, obviously shorter though.
I don't know much about bayonets. I assume it's for a Legend but I've only ever seen NIB Legend examples.... Never just a bayonet by itself.
