The Mambi-1 AMR is a semi-automatic anti-materiel rifle designed and manufactured in Cuba.
It was named after the Mambises, who were rebel soldiers that fought against the Kingdom of Spain during the Cuban War of Independence (1895–1898).
[4] The Mambi was designed to be used against a variety of soft-skinned ground vehicles, small boats, and even helicopters.
It is fitted with a muzzle brake to help reduce recoil created by the round it fires.
[4][3] The weapon is designed to be fired from a prone position due to large amounts of recoil.
