PMC Linked .50 BMG 660-grain FMJBT ammunition (brand part no. 50A Link (M/B)) is belted for crew-served machine guns like the M2, not loaded loose for a bolt-action rifle. PMC assembles each round onto a disintegrating steel link, so the belt feeds continuously through the gun without manual loading between rounds. The 660-grain full metal jacket boat-tail bullet is the same weight and profile long used in ball ammunition for the .50 caliber machine gun, giving predictable function and trajectory at .50 BMG velocities. Packed 100 rounds to a genuine M2A1 ammo box, it is built for range days behind a belt-fed gun rather than precision single loading. For shooters running a .50 caliber machine gun or a linked-feed upper, this is purpose-built ammunition.

Key Specifications

• The chambering is .50 BMG, the cartridge built for heavy machine guns and long-range rifles alike.
• The bullet weighs 660 grains, matching the traditional ball-ammunition weight for .50 caliber.
• The projectile is a Full Metal Jacket Boat-Tail (FMJBT), a non-expanding bullet built for function and flight, not terminal expansion.
• The boat-tail base reduces drag downrange, holding velocity better than a flat-base bullet at .50 BMG distances.
• The rounds are linked on a disintegrating belt, feeding continuously through belt-fed .50 caliber machine guns such as the M2.
• Ammunition ships in a genuine M2A1 ammo box, the standard steel container used to transport and feed linked .50 caliber belts.
• Each box holds 100 rounds, a practical quantity for a sustained range session behind a belt-fed gun.
• Cost works out to about $5.59 per round, reflecting the reality of .50 BMG ammunition pricing.
• Shipping weight runs approximately 35 pounds per box, reflecting the density of a full linked .50 BMG belt.
