Norinco M99

About the Norinco M99

The Norinco M99, also known as the Zijiang M99 or Type 99, is a Chinese semi-automatic anti-materiel rifle chambered in 12.7x108mm, developed by China North Industries Corporation (Norinco) for the People's Liberation Army. The rifle uses a direct impingement gas operating system with a rotating bolt, feeding from a 5-round detachable box magazine. Designed for engaging lightly armored vehicles, equipment, and personnel at extended ranges up to 1,500 meters, the M99 features a massive multi-port muzzle brake to mitigate the substantial recoil of the 12.7mm cartridge, along with an adjustable bipod and rear monopod for stable shooting positions. The buffered buttstock further absorbs recoil impulse, making sustained fire practical despite the weapon's large caliber.

The Norinco M99 represents China's entry into the anti-materiel rifle market, designed during the PLA's rapid modernization of the late 1990s. Its semi-automatic action gives Chinese forces a capability that most competitors achieve only with bolt-action designs, allowing rapid engagement of multiple targets or fast follow-up shots against moving vehicles.

Norinco M99 specifications

The M99 was one of China's first domestically designed anti-materiel rifles, entering service in 1999 as part of the PLA's modernization program. The improved M06 variant features refinements to the gas system and ergonomics. The rifle's semi-automatic action provides a significant advantage over bolt-action competitors in rapid follow-up shots against moving or multiple targets. The direct impingement system, while less common in Chinese firearms design, was chosen for its weight savings compared to a piston-driven system. The M99 has been exported to several countries and has appeared in various regional conflicts throughout Asia and the Middle East.
