Light Machine Gun & Medium Machine Gun Cradle

Finally, we come to the Light Machine Gun & Medium Machine Gun Cradle, also from the U.S. Army Armament Research, Development and Engineering Center. It "provides a more stable and more accurate firing platform and reliable, twist-free ammo feeding regardless of weapon orientation," the Army says. "The cradle eliminates the hazard of a full-length belt of ammo hanging loose from the weapon as well as machine gun stoppages due to twisted or snagged ammo by keeping ammo in-line with the feed tray."
