M82 vs M107A1: What Changed

The Barrett M82A1 is the foundational design: a semi-automatic .50 BMG rifle with a 29-inch fluted barrel, Picatinny rail, and Barrett’s twin-chamber muzzle brake. The M107A1 is the current US military designation representing production refinements including a lightweight titanium barrel key, an updated buffer system, and improved ergonomics — but the fundamental design is the same short-recoil semi-auto that Barrett introduced decades ago. Civilian M82A1 and M107A1 rifles are functionally equivalent; the M107 designation on civilian rifles reflects the military-mirrored specification rather than a distinct mechanical change. Both platforms accept the same 10-round box magazines and the same scope mounting systems.

What .50 BMG Actually Does

The .50 BMG (12.7x99mm NATO) cartridge produces approximately 13,000 foot-pounds of muzzle energy — roughly ten times a .308 Winchester. At practical engagement distances, the .50 BMG delivers enough energy to defeat light armor, disable vehicle engines, destroy crew-served weapons, and engage aircraft. For civilian use, the .50 BMG’s practical applications are long-range target shooting and competition where the combination of retained energy at extreme range and excellent ballistic coefficient make it competitive at 1,000–2,000 yards. The M82/M107 is also popular among collectors and enthusiasts who want the most powerful semi-automatic rifle available.

Practical Considerations

The Barrett M82/M107 is a large, heavy platform — the rifle weighs approximately 29 pounds unloaded, is 57 inches overall with the 29-inch barrel, and requires a bench, bipod, or prone position for practical use. It is not a field rifle; it is a precision long-range platform. Ammunition costs are substantial — .50 BMG ranges from $3 to $6+ per round for quality ammunition. Suppressor options exist (Barrett’s own suppressor system) but add considerable length and cost. State restrictions apply in California and a handful of other states that prohibit .50 BMG rifles; verify your state’s laws before purchase.

Frequently Asked Questions: Barrett M82 / M107

What is the Barrett M82?
The Barrett M82 is a semi-automatic .50 BMG anti-materiel rifle developed by Ronnie Barrett in the 1980s and adopted by the US military as the M107. It fires the .50 BMG cartridge to effective ranges beyond 1,800 meters and is the most recognized .50 BMG semi-automatic platform in history.

Is the Barrett M82 legal for civilians?
Yes in most states — the M82/M107 is a standard semi-automatic rifle and is legal for civilian purchase in the majority of US states. California and a small number of other states prohibit .50 BMG rifles specifically. Always verify your state’s laws. No NFA registration is required for the standard M82/M107.

How far can the Barrett M82 shoot accurately?
The M82/M107 is effective to approximately 1,800 meters (nearly 2,000 yards) against point targets with a skilled shooter and quality optics. The .50 BMG cartridge’s high ballistic coefficient and retained energy make it competitive at distances beyond the practical range of most other rifle cartridges.

How much does a Barrett M82 cost?
Barrett M82A1 and M107A1 rifles typically retail between $9,000 and $12,000 depending on configuration and accessories. Barrett also produces the MRAD bolt-action and the M95 bolt-action .50 BMG at lower price points for buyers who want .50 BMG capability at a lower entry cost.
