M2HB Parts
Browning .50 Cal & M3 Tripod • 6 SKUs
Hard-to-find parts for the legendary Browning M2HB — “Ma Deuce,” the .50 caliber heavy machine gun that has served for nearly a century — and its M3 tripod. We stock USGI and mil-spec components for restorers, collectors, and semi-auto .50 builders: the retracting slide, buffer, and barrel support, plus the T&E mechanism and M3 pintles that bring a tripod back to life.
M2HB Parts
The Browning M2HB is one of the most storied weapons ever made, and this page gathers the genuine and mil-spec parts we stock to keep one — and its M3 tripod — running. You’ll find them with the rest of our military surplus parts.
Parts for “Ma Deuce”
The M2HB — the “Heavy Barrel” Browning .50 caliber machine gun, known the world over as Ma Deuce — was designed by John Moses Browning and has been in U.S. service since the 1930s, making it one of the longest-serving firearms in history. The components on this page are USGI and mil-spec parts for that gun and its M3 ground tripod, meant for collectors, restorers, and builders of semi-automatic .50 BMG rifles. They are parts and accessories only — not the registered receiver. An actual M2 is a machine gun regulated under the National Firearms Act and transferred only as a Class 3 item.
Receiver & Charging Group Parts
For the gun itself, the M2HB Retracting Slide Assembly is the charging group, complete with handle and ready to mount on either side of the receiver, and the Browning M2HB Buffer Assembly is a genuine GI-spec contract overrun that drops in for repairs, new builds, or a semi-auto M2. The United Defense M2HB Barrel Support is machined to MIL-SPEC dimensions in hardened, phosphate-finished steel and fits both full-auto and semi guns. These are exactly the sort of components our gunsmith tools were made for, and they belong in the broader gun parts catalog alongside other United Defense components.
The M3 Tripod: T&E and Pintles
A .50 is only as steady as its mount. The T&E (Traverse & Elevation) Mechanism for the M3 tripod gives precise, repeatable aim with a 425-mil traverse range and a graduated mil dial, the factory-new M3 .50 Pintle is the USGI mount that connects gun to tripod (and works with both .30-cal and .50-cal Browning setups), and the M3 Pintle Parts Set supplies the cross bolt, castle nut, and cotter pin to finish the job. Restoring a piece of history makes a great display alongside our other military collectibles, and if you shoot a semi-auto .50, stock up on .50 BMG rifle ammo. Every order ships from Keep Shooting with fast handling and our satisfaction guarantee.
