.50 Caliber Military Weapon Parts and Accessories

Explore .50 caliber military weapon parts, feed components, backplates, grips, recoil-system parts, barrel supports, solenoids, mounts, brackets, hardware, tools, and related accessories. This category covers components associated with the Browning M2 and M2HB, aircraft AN/M2 and M3 machine guns, M85 vehicle weapon, and other .50 BMG military systems. Although these weapons share the same nominal caliber, differences in operating speed, mounting, feed direction, and application mean many components are model-specific and not interchangeable. Any ammunition or ordnance included for display is inert or deactivated and intended for collecting, museum exhibits, technical study, identification, or restoration reference.
