The Fusil Automático Doble (usually shortened to FAD, Dual Automatic Rifle in English) was a bullpupassault rifle designed to be a back-up weapon for armored crews.
The FAD offered a built in 40mm pump-action grenade launcher and rather unconventional looks. The rifle was designed by Salomon Braga Lozo of SIMA Electronica, a division of the Peruvian state-owned SIMA (Servicio Industrial de la Marina) shipyards, located in the port of Callao. The rifle is chambered for the 5.56x45mm NATOcartridge. The weapon is designed to be a low recoil, weight and volume platform while still offering precision, adequate range and ergonomics. The charging handle is located on the right side of the rifle, near the ejection port. As of 2016, the weapon has yet to be put into full production and/or adopted; however, it is widely assumed that the project for the weapon has been shelved as it has not been seen in the last few years, and the company that supposedly produces the weapon, SIMA Electronica, makes no mention of the FAD on their website.
