The Sig Sauer 516 G3 is a semi-automatic AR rifle chambered in 5.56 NATO with a 16″ threaded barrel. It has a bronze Cerakote finish and a 30-round magazine capacity. The muzzle is threaded 1/2×28 and comes with a SIG flash hider-compensator.
What sets the 516 G3 apart
This rifle runs a short-stroke piston with an adjustable gas system, so you can set the gas to suit your load. The handguard is free-floating and uses M-LOK. There is a rear charging handle and a side charging handle, and both are non-reciprocating. The controls are fully ambidextrous, which helps left-handed shooters. The trigger is a Matchlite Duo curved design, and the stock is a Magpul DT polymer stock. Sig Sauer also reinforces high-wear areas with steel. The 516 series has a long record in harsh environments worldwide, and this G3 version is built on that design.
It fits shooters who want a piston AR for the range, training classes, or a home-defense or general-purpose rifle. Left-handed and right-handed shooters can run it the same way.
Gear that pairs well includes a red dot or magnified optic, a sling, and a weapon light or grip mounted on the M-LOK handguard. Spare 30-round magazines and a padded rifle case round things out. The 1/2×28 threads also take other muzzle devices that use the same thread.
