Can't Access Most Weapons

[Dumbermancer]

Hi, I can't find this topic anywhere else. I can only access the most basic weapons. I can only buy the two base shotguns, just the single shot rifle, etc. I can't get the AK, the automatic shotgun, m99, etcetera. But I seem to have full access to flame weapons and berserker weapons. Do i need to level more or is this a glitch? Thanks in advance.

What's your level and perk?

I have Level 5 Sharpshooter and Level 3 Support. Just 1st level in Commando. If I just unlock more weapons as I level that's fine, I just don't know how that works. I'm otherwise having a blast on the servers ^_^
