The M5A2 Carbine is a weapon manufactured by Eltvedt Firearms. It was even lighter than its predecessor, the M5A1. Having most of the features of the M5A1, there were two major changes: 1. The magazine is curved a bit. 2. The grip is thinner, longer, and straight. Several years later the M5A3 was made. However, it wasn't made the main weapon of the U.S. Armed Forces.
