The Swiss SIG 550 is a 5.56mm assault rifle that takes 20, 25, and 30 round clear magazines. It can be in either all black or have olive drab stocks. It comes with an adjustable stock, heavy target barrel, bipod, scope, match pistol grip, and match trigger. The SIG 550 is also fairly expensive so it hasn't been popular with most militaries but some police forces and counter-terrorists have bought some. It is more meant for target shooting but can be used as a sniper rifle as it is used by Elsa de Sica.
