SIG Sauer unveiled two new weapons at AUSA 2018, namely their new light belt-fed machine gun, MCX-MR and associated lighter ammo.
The light machine gun was shown chambered in .338 Norma Magnum, intended for associated ballistic requirements of the US Army’s Next Generation Squad Automatic Rifle Other Transaction Authority (OTA) currently underway and for US Special Operations Command’s medium machine gun requirement. The new light machine gun has a top rail that extends over the feed tray cover for easy zeroing. Weighing less than 10kg SIG Sauer officials stated it has a range of 2,000 kilometres.
SIG Sauer also unveiled their MCX-MR (Medium Range) prototype, intended for the US Army's Next Generation Squad Weapon (NGSW) programme. Next to the rifle, the company showcased their newly developed Hybrid Ammo, a three-piece metallic, non-polymer, design with a brass body, offering 20% reduction in overall cartridge weight as well as increased velocity over conventionally produced ammunition.
