The Sig Sauer SIG516 G3 5.56mm Black 11.5" AR Pistol delivers a refined gas‑piston system in a compact, brace-equipped configuration. Built on an aluminum receiver with a free-floating M-LOK handguard and threaded 11.5" barrel capped by a SIG flash hider/compensator, this pistol is designed for cleaner operation and consistent performance with .223 Rem/5.56 NATO ammunition.

With fully ambidextrous controls, a Matchlite Duo curved trigger, and a Magpul BSL stabilizing brace, the SIG516 G3 is well suited for range use, training, and general-purpose defensive roles where a shorter overall length is preferred. Its adjustable short-stroke piston system helps maintain reliability across different loads and conditions, while Sig Sauer’s attention to detail and long-standing reputation for quality engineering are evident throughout the build.
