You made some very interesting turrets with this mod, but after testing them with a high pollution base, a few balance problems came out:

Minigun turret: Eats ammo so fast, i had to use a stack inserter to keep up, needs special clips with high ammo count, something like 100?

Sniper turret: It has less than 50% of Sniper Rifle, damage bonus with the same fire rate, the damage bonus should be equal to sniper rifle methinks.

Cannon turret: for static, explosive ordnance dispenser, the range is so short it's very awkward to use

Rocket turret: Perfect, no comment.

Flamethrower turret - No problems, propane gas turrets are awesome and i love them.
