This image is a Type 95 you can see the AK style magazine interface.
From here on All are Type 97 note the whole of the carry handle assembly seems to have been replaced
The Optic is a US made Leopold and Stevens HAMR this is a 4x24 powered optic mean to compete against the Trijicon ACOG
This is a Raytheon Elcan Specter also meant to compete with the Acog also I think in the 4x power model
Odd no logo.
Glocks are fine but I'm more of a Sig kinda guy.. Although my dream sidearm is still the hk usp.
