SIG Sauer SIG516 G3 5.56 NATO Rifle

Description

Product Overview

The SIG Sauer SIG516 G3 is a semi-automatic 5.56 NATO rifle built around a short-stroke gas piston system and a cold hammer forged 16-inch barrel. Its free-floating M-LOK handguard supports accessory placement while the Picatinny rail receiver provides a stable platform for optics. Fully ambidextrous controls, including the bolt catch, magazine catch, safety, and non-reciprocating charging handle, make the rifle adaptable for right- or left-handed operation. Steel-reinforced components in high-wear areas and the SIG Matchlite DUO curved trigger support dependable operation and precise trigger control.
