Victory Plastics...they made lots of this sort of thing. Bayonet scabbards and K-Bar scabbards.

Some nice stuff, some needs a bit of help. I know that's all part of it. I have one of those Mk2s with a fiber scabbard too...

Too bad about the handguard though, someone will still take it and glue it or microbed or some such... Yes, neat piston nut. A few other military things?

Part...I only see half. Like, the left side. Hope it's just optics and the rest is complete.
