OK, I tested it, and noticed a few bugs
This isn't critisism, just pointing out some stuff ;D
1. None of the guns have pics in the gear section
2. The '100rd' AK acts just like a PK. It can't fire semi auto, and in the top left, it says PK
3. The '20rd' AK acts like a M21. It can't fire full auto, and it also says M21.
4. The 30rd and 20rd AKs have the normal functions, but when you press 'space' twice, it has a mode either called 'AK4730rd' or 'AK4720rd', with no ammo. If you click fire whilst on these modes, the game stalls and goes down to windows.
5. Same above with the AK47 Sniper.
6. The 10rd AK acts just like a SVD Dragonov
