SIG516 G3

The SIG516 G3 builds on the trusted legacy of the 516 series, blending modern enhancements with a proven, battle-tested design. Deployed in some of the harshest environments worldwide and perfected right here in New Hampshire, the SIG516 G3 draws on more than a decade of real world user feedback to deliver exceptional durability and reliability within its class.

Capable of performing under the harshest conditions, the SIG516 G3 utilizes premium components and an innovative feature set to deliver uncompromising reliability. Inside the rifle, a short-stroke piston with an adjustable gas system keeps the SIG516 G3 in flawless operation with the ability to tune the gas settings to meet the mission at hand.

Chambered in 5.56 NATO, the SIG516 G3 is standard with a 16-inch cold hammer forged barrel with a 1:7-inch twist rate. The intuitive design of the SIG516 G3's unique rear and side non-reciprocating charging handle allows the rifle to be easily operated in any manner, in any condition.

To support long-term operational use and extended reliability, the rifle features steel-reinforced components for high-wear areas (cam path and feed ramp). The SIG516 G3 is standard with fully ambidextrous controls, including the bolt catch, magazine catch, safety, and charging handle. Additional on-rifle components include a SIG Matchlite DUO curved trigger, SIG flash hider compensator, and a free-floating M-LOK handguard.

With its proven performance capabilities, upgraded feature set, and established history of durability in the field, the new SIG516 G3 continues to raise expectations for an AR-15 piston system.

The new SIG516 G3 sets new standards for durability, reliability, and user convenience in a modern sporting rifle.
