The Stoner 63 is a modular small arms system designed by Eugene Stoner, the engineer behind the AR-15/M16 platform, allowing a common set of components to be reconfigured into rifle, carbine, and light machine gun variants using the same receiver and operating group. Manufactured under license by Cadillac Gage, the system saw its most notable combat use with United States Navy SEAL platoons in Vietnam, who adopted small numbers of the light machine gun configuration for its favorable weight and volume of fire compared to contemporary belt-fed weapons. Although the Stoner 63 never achieved widespread adoption across the broader U.S. military due to reliability concerns and the logistical complications of its modular parts, its use by SEAL units gave it lasting notoriety as one of the more exotic small arms of the Vietnam War. Dated to 1967, this example comes from the period when the system saw its limited but historically significant special operations deployment.
