A conversion system for .30 caliber semi-automatic carbines permits selective use with .22 caliber ammunition. Modified barrel, bolt, operating slide and magazine sub-assemblies easily replace the corresponding original sub-assemblies to provide for direct blow-back operating slide actuation with .22 caliber ammunition. The replacement parts are of such simplified construction as permits manufacturing and sales as a conversion kit at a fraction of the original cost of the .30 caliber carbine to be converted. The conversion technique also provides for the independent manufacture of a unique .22 caliber semi-automatic carbine having the general appearance and "feel" of the standard .30 caliber M1 carbine.
