The Sig Sauer 516 G3 5.56 NATO 11.5" 30RD SBR is a compact, semiautomatic short‑barreled rifle built around a proven short‑stroke gas piston system. Its 11.5" threaded barrel with Sig flash hider compensator is paired with a free‑floating M‑LOK handguard, giving shooters a rigid, accurate platform with plenty of room for lights, grips, and other accessories. Fully ambidextrous controls and non‑reciprocating charging handles make the rifle intuitive to run from either shoulder.

This configuration is well suited for shooters seeking a maneuverable rifle for training, range work, or duty use where compact size and controllability matter. The six‑position Magpul DT stock allows quick length‑of‑pull adjustments, while the Matchlite Duo curved trigger supports consistent, predictable breaks. Combining modern ergonomics with the long‑running 516 lineage, this SBR reflects Sig Sauer’s focus on reliability, refinement, and user‑driven design.
