History

Initially rejected by the Brazilian Army, Uirapuru was given a second life in 1976 after implementing improvements. The weapon was an initial design assembled by members of the Brazilian Army Academy of Engineering, one of the original members was later designated to continue development and make some important changes to bring the weapon system to Brazilian Army standards.

Classified as a general purpose machine gun, the system can be a vehicle (including coaxially acting armor), ocean-going ships or aircraft, and as part of an infantry squad acting as a support fire. Uirapuru fires NATO standard 5.56x51mm cartridges from a variable length belt ammunition system. The barrel features a quick-change system and flash suppressor, as well as a convenient bipod and wooden stock for supporting fire.

An optional tripod is also available for continuous FireWire reels, and there's an awkwardly angled carry handle for easy portability.
