My pons or any pons can't shoot 1.6

Mods i have are Combat extended 1.6.7 War crimes expanded 1.6 Speech bubbles 1.6 And harmony

No one is able to shoot guns Idk how or why Guns don't work and it's driving me crazy I want to raid a nudist trip imprison some and line them along the wall But i can't because i can't use guns

Any ideas why that is happening
