The SIG516 G3’s piston system diverts gas away from the bolt carrier group, significantly reducing carbon fouling and heat transfer to critical components. This design enhances reliability in adverse conditions and extends service life. Chambered in 5.56 NATO, its 1:7 twist barrel stabilizes a wide range of bullet weights, making it a robust platform for duty, defense, and extended range sessions.
