SIG SAUER 516 Mohawk Semi-Auto Rifle R516G3556N16B — Description

The SIG SAUER 516 Mohawk R516G3556N16B is a premium 5.56 NATO semi-automatic rifle built around SIG Sauer’s proven short-stroke gas piston operating system. Designed for reliability in demanding environments, the 516 Mohawk combines modern AR-platform ergonomics with enhanced features such as a side-charging handle, fully ambidextrous controls, and a modular configuration for versatile shooting applications.

The Mohawk configuration features a 16-inch barrel, black finish, Magpul DT adjustable stock, and a full-length modular handguard system. The rifle’s piston-driven action helps reduce fouling compared with traditional direct-impingement systems, while the adjustable gas system allows tuning for different ammunition and shooting conditions.

Designed for users who value durability, adaptability, and fast manipulation, the SIG 516 Mohawk includes ambidextrous controls, a non-reciprocating side charging handle, and compatibility with standard AR-pattern magazines. Its combination of piston reliability and familiar AR controls makes it a versatile rifle platform for recreational shooting, training, and field use.
