## Description of the bug
if you spawn in as the solar devils ert as an sg, the frontline mode toggle doesnt appear on your gun or hud, but if you have it hotkeyed it still toggles on, but you cant toggle it off

## What's the difference with what should have happened?
i expected for the sg to either have toggleable frontline mode, or prevent frontline mode toggling at all

## How do we reproduce this bug?
1) Spawn as Solar Devils Smartgunner
2) Bind Toggle-Frontline-Mode hotkey to any key you want
3) Equip Smartgun
4) toggle frontline mode with hotkey
5) ???
