I would recommend L series timing pulleys with neoprene belts, or a smooth pulley could work too.

you really shouldnt have to unless the drum is a 5inch od

if you have a outer support for your weapon motor shaft I would use the teeth with a kevlar belt but if it doesnt I would go with a inverted neoprene belt

because your more likely of getting a big bite on bigger weapons and would put more stress on the belt, but beaters tend to do that more than drums.
