SIG SAUER takes its proven piston-driven rifle platform to the next level with the SIG516-MOHAWK G3. Building on more than a decade of operational experience, this latest evolution combines a proven design with modern engineering solutions focused on maximum reliability, durability, and user comfort. The result is a semi-automatic rifle designed for shooters who demand uncompromising performance from their equipment.
Chambered in the proven 5.56×45 mm NATO / .223 Remington cartridge, the SIG516 G3 offers an excellent combination of accuracy, manageable recoil, and broad ammunition availability. At the same time, its robust design is engineered to maintain reliable operation even under demanding conditions where conventional direct-impingement AR-15 systems can reach their limits.
A piston system designed for maximum reliability
The key difference compared to a conventional AR-15 is the Short-Stroke Piston gas system. This design reduces the amount of hot combustion gases and fouling entering the action, helping to keep the operating mechanism cleaner and contributing to reliable operation during intensive use.
The system is complemented by an adjustable gas regulator, allowing the rifle to be tuned to different ammunition types, operating conditions, or the use of a suppressor. This gives the shooter greater control over the rifle's operating characteristics and allows the platform to be adapted to specific requirements.
Cold hammer-forged barrel and outstanding durability
The rifle features a 16" (406 mm) cold hammer-forged barrel with a 1:7" twist rate, making it suitable for a broad range of modern 5.56 NATO ammunition. Cold hammer forging provides excellent durability and long service life, making the barrel well suited to demanding and intensive shooting.
The muzzle is threaded 1/2"-28 TPI and fitted with a SIG Flash Hider-Compensator, which helps reduce muzzle flash while simultaneously limiting muzzle rise during rapid fire.
Innovative controls and reinforced construction
One of the most distinctive features of the SIG516 G3 is its non-reciprocating rear and side charging handle system. Both charging handles remain stationary during firing, allowing the shooter to operate the rifle comfortably from different shooting positions without the charging handle moving with the bolt carrier.
SIG SAUER has also reinforced the areas subject to the highest levels of stress with steel inserts, including critical areas around the bolt carrier guide path and feed ramp. These solutions contribute to increased durability and long-term reliability even under heavy use.
Fully ambidextrous ergonomics
A modern rifle should work equally well for every shooter. The SIG516 G3 therefore features fully ambidextrous controls, including the safety selector, magazine release, bolt catch, and charging controls. Right- and left-handed shooters can enjoy the same intuitive and comfortable operation.
The rifle is equipped with the SIG Matchlite Duo Curved Trigger, providing a clean and consistent trigger pull with a fast reset. This makes the SIG516 G3 equally suitable for dynamic shooting and more precision-oriented disciplines.
Modern modularity without compromise
The SIG516 G3 features a free-floating M-LOK handguard manufactured from lightweight alloy, providing plenty of mounting space for lights, lasers, foregrips, and other accessories. The full-length Picatinny rail on top of the rifle provides a solid mounting platform for a wide range of optical sights.
Ergonomics are further enhanced by a six-position Magpul DT adjustable stock, allowing the rifle's length of pull to be quickly adapted to different shooters and shooting positions. Standard AR-compatible components and interfaces also provide extensive possibilities for future customization.
Ready for whatever comes next
With an overall length of 838–927 mm, an approximate weight of 3.5 kg, and a supplied 30-round AR-15-compatible magazine, the SIG516 G3 delivers an excellent balance of performance, handling, and durability.
The SIG SAUER SIG516-MOHAWK G3 is built for shooters who expect more than a conventional AR-15. Its short-stroke piston system, adjustable gas regulation, high level of modularity, premium construction, and fully ambidextrous controls create a rifle designed for reliable performance in demanding conditions.
