SIG Sauer MG 338

The SIG MG 338 is primarily chambered in .338 Norma Magnum and has an effective range of approximately 1,700 meters, approximately twice the effective range of 7.62x51mm, while at 1,000 meters, it is still capable of penetrating Level III armor.

[1] The MG 338 can be switched to fire 7.62×51mm by changing out the barrel, bolt, feed tray, and cover.

[3] The MG 338 is fully ambidextrous and is capable of being fed and charged from the right or left side which can make mounting the machine gun to various vehicles easier.

[8] In 2017 United States Special Operations Command (SOCOM) issued a solicitation for a .338 Norma Magnum machine gun.

[18][9] The US Army also looked at adopting the weapon alongside SOCOM,[19] and it was also evaluated by the Marine Corps' MARSOC.
