.50 BMG Rifles
The .50 BMG (Browning Machine Gun) is the largest centerfire rifle cartridge commercially available to civilians — a massive round originally designed for the M2 Browning machine gun that pushes a 647–750 grain bullet to 2,700+ fps, delivering extreme long-range capability measured in miles rather than yards. .50 BMG rifles from Barrett, Serbu, and other manufacturers are purpose-built for extreme-distance target shooting, anti-materiel applications, and the simple, visceral experience of firing one of the most powerful shoulder-fired weapons in existence.

Barrett M82A1 and M107A1: The Semi-Auto Standard
The Barrett M82A1 is the rifle that defined the modern .50 BMG market — a semi-automatic, recoil-operated .50 caliber that the U.S. military has fielded since the 1980s as the M107. The M107A1 is the current-generation military variant with a titanium barrel key, suppressor-capable muzzle brake, and reduced weight. Barrett also offers the bolt-action M99 and M95 for buyers who want .50 BMG capability at a lower price than the semi-auto M82.
Serbu BFG-50 and RN-50
Serbu Firearms offers the most affordable entry into .50 BMG ownership. The RN-50 is a single-shot, breech-loading .50 BMG that fires by striking the primer with a hammer — the absolute lowest-cost path to .50 caliber shooting. The BFG-50 is a bolt-action repeater with a more conventional shooting experience. Both are built in Tampa, Florida, and offer genuine .50 BMG capability at a fraction of Barrett pricing.
What Is .50 BMG Used For?
At the civilian level, .50 BMG rifles are used for extreme long-range target shooting (1,500+ yards), ELR (Extreme Long Range) competition, and recreational shooting. The cartridge’s military role is anti-materiel — disabling vehicles, equipment, and hardened targets at ranges exceeding a mile. At the recreational level, it’s one of the most dramatic shooting experiences available: the concussive blast, the visible trace of the bullet in flight, and the impact energy at distance are unlike anything else in the civilian market.
.50 BMG Ammunition
Factory .50 BMG ammunition is available from Federal, Hornady, PMC, and military-surplus sources in ball, tracer, API (armor-piercing incendiary), and match-grade configurations. Match ammunition from Hornady (A-MAX 750 grain) is the standard for precision long-range work. See our .50 BMG ammunition page for current inventory. Ammunition cost runs $3–6+ per round depending on type.
Practical Considerations
.50 BMG rifles are heavy (20–30+ lbs), long (45–57 inches), and loud. They require a range that can handle the distance and energy — most indoor ranges and many outdoor ranges do not permit .50 BMG. Recoil on a semi-auto Barrett with a muzzle brake is surprisingly manageable for the caliber; bolt-action .50s and the single-shot Serbu kick harder. Transportation and storage require planning due to size and weight.
