Developed in the late 40s and early 50s, the M37 was a refinement of Browning's 1919 air cooled machine gun, in particular integrating an ambidextrous feed mechanism. With mild reconfiguration, the M37 could be used as a coaxial weapon or a flex-mount weapon on an armored fighting vehicle, or on the ground with a conventional tripod. This example is configured for use as a coaxial gun or in a similar mounting, with an ejection chute to direct links downward and an extended charging handle that can be pulled from the rear of the weapon. Adjustable blade front and folding ladder rear sights, with a ventilated heat shield around the barrel, Saco-Lowell markings on the right sideplate with "DoD eagle", "RBA" and "BA4-4/69" markings, importer mark, and a checkered pistol grip. "SAK" markings are present on multiple internal components, with a sliding safety integrated into the trigger mechanism. Included with the lot is a folding tripod (sans pintle and T&E mechanism).

Very fine, with 90% plus arsenal refurbished parkerized finish, showing some light scuffs and minor cycling/handling marks. Mechanically excellent.
