A belt-fed Gatling-style gun is provided. In some embodiments, the belt-feed system allows a plurality of individually separable belt links to be connected in series to feed cartridges to a belt-fed rotary gun. Each individual belt link may be removably connected to a series of belt links to facilitate ease of loading and making belts of ammunition of any length.

An assembly for quickly attaching and detaching the guide bar to and from the rotor housing of a minigun is provided. The assembly comprises a guide bar and a rotor housing. The guide bar includes a front end having a pinhole extending through the front end and a rear end having a locking cam. The rotor housing includes a recessed channel configured to receive the locking cam and a spring-loaded lock pin assembly configured to secure the front end of the guide bar. The guide bar is secured to the rotor housing when the locking cam is inserted into the recessed channel and the spring-loaded lock pin assembly secures the front end of the guide bar. The assembly allows the guide bar to quickly be attached and detached from the rotor housing without the need for tools. The rotor housing may be designed without a yoke to reduce weight.

A spade grip attachment assembly for securing a spade grip to a minigun includes a first adapter member and a second adapter member. The first adapter member is on the spade grip. The second adapter member is on the minigun. The first and second adapter members are configured such that one is receivable in the other. Each adapter member can define a pair of coaxially aligned pin holes that align to form a passage in which a fastener is receivable when one adapter member is received in the other. The fastener is receivable in the passage to releasably secure the first adapter member to the second adapter member.
