As it belonged to the owner of the fireworks manufacturer of the same name, the weapons manufactured by FAM were sold under the brand name Caramuru.[2] The factory developed several weapons such as the R1, R6 and R7 revolvers (based on the Smith & Wesson Ladysmith), hunting rifles, cartridge cases, shotguns and some series of rifles in caliber .22 LR.[2][1] Some of its single-choke rifles were even manufactured by the São Paulo company Lerap, under order from FAM itself.[3]
Today Caramuru revolvers are considered a collector's item due to their rarity, it was considered a simple and economical weapon for transportation or simple personal defense, they also had a very low price if compared to traditional brands of weapons at the time such as Taurus, Rossi and INA. The company also developed a version of the R3 revolver in .38 Special caliber and a prototype of a machine gun based on the Israeli UZI.
