Here's a thought: Turrets

Ignoring my very bad title, the idea is this:

Let the turret be crafted with any gun, not just the AK. Depending on what gun you use, determines what type of turret you get. Imagine a short ranged turret made with a pump-shotty, or a custom smg? Or a rocket turret? might sound a little OP but it'd give us a practical use for all those high-velocity rockets we end up with. Or even an M249? It'd essentially be the current turrets bigger, meaner brother.

obviously, some guns like the waterpipe or the eoka might not be applicable, and the semi auto pistol/rifle are probably not a good choice for turrets.
