| ~~~~~~~~~~~~~~~ The idea for a lite machine gun in .22 caliber did’t start with the FN P90 in 5.7x28mm, which is a hot item today, in 2007. It started way back in the 1960's. One of them was the 5.7x33 Johnson Spitfire, (.22/.30 Carbine) designed by a Boston lawyer and Captain in the Marine Corps Reserve named Melvin Johnson Jr.. Mr. Johnson turned away practicing law, to his passion, cartridge/ rifle design earlier in 1937 to designed, built, and successfully tested both a semiautomatic rifle and a prototype light machine gun (LMG). One of his last postwar ventures was in 1963, when he introduced a 5.7 mm caliber version of the M1 Carbine, aka "the Spitfire". Johnson promoted the smaller caliber and the modified 22/30 carbine as a survival rifle for jungle or other remote areas. While the concept had some military application when used for in the selective-fire M2 Carbine, it was not pursued and few 5.7 mm Spitfire carbines were made. This is basically a military Wildcat, or now a proprietary cartridge as a few have been produced commercially. ~~~~~~~~~~~~ |
