This is just a mod of the SMuFF, where a standard servo is being used as a Revolver replacement.
Benefits so far:
Less stress on the Bondtech gears while loading / unloading
not as bulky
one stepper motor less (though, the costs won't change)
somewhat easier to assemble.
Let me know what you think.
