Welcome to immediately’s Picture of the Day! The LUSA submachine gun, developed by Portugal’s INDEP in 1983, blended design parts from the HK MP5 and Uzi. Although using the MP5’s set off housing, it simplified the internals with a straight blowback motion and welded bolt/service unit. Notable options included quick-change barrels and ambidextrous controls, although it lacked a bolt hold-open machine. When INDEP ended manufacturing in 1992 after restricted adoption, the design discovered new life in America. In 2004, three U.S. businessmen bought the manufacturing rights and tooling, forming LUSA USA. The corporate produced a number of civilian variants together with the Mannequin 94 carbine with 16-inch barrel and pretend suppressor, the SP89 pistol, and the A3 short-barreled rifle. Although well-made, the LUSA’s proprietary 30-round magazines (really helpful to load with 28 rounds for dependable insertion) proved a limitation. Manufacturing ceased in 2011 because of prices, however the design influenced the later NiteScout carbine, which addressed some limitations by adopting Uzi magazines and MP5-style controls.
