About the Sig Sauer 516 Gen
The Sig Sauer 516 Gen 3 is a piston-driven AR platform rifle chambered in 5.56 NATO with a 16 inch barrel and a 30 round magazine. Instead of direct impingement, the 516 runs a short stroke piston operating system with an adjustable gas regulator, reducing heat and fouling in the upper while giving shooters a tunable gun for suppressed and unsuppressed use.
A free floating M-LOK handguard surrounds the barrel for clean optic and accessory mounting, and rear and side non reciprocating charging handles let the shooter run the gun from either side. Fully ambidextrous controls, steel reinforced components in high wear areas, and the Matchlite Duo curved trigger make the 516 a duty ready carbine rather than a basic range rifle. The Sig flash hider compensator keeps muzzle movement flat for fast follow up shots, and the rifle ships with a standard pistol grip and collapsible stock for fitment across different shooters and kit setups.
