The SIG 716 Tactical rifles are gas operated weapons that use Ar-15 / M16 configuration, with aluminum alloy upper and lower receivers assembled by two captive cross-pins. The basic Ar-15 / M16-style rotary bolt gas operated action is enlarged and strengthened to work with more powerful 7.62mm / .308 caliber ammo and improved with addition of the short-stroke gas piston that runs inside handguards, above the barrel. The gas block is equipped with manually adjustable gas regulator. The trigger unit, manual safety and feed system (magazines, bolt release etc) are also similar to the Ar-15 / M16. The SIG 716 Patrol rifles feature shorter 16 inch barrels and adjustable M4-type buttstocks. The SIG 516 Precision Sniper rifles have longer 20-inch heavy profile barrels and adjustable 'sniper' stock. In either version, barrels are chrome-lined. The sighting equipments is installed using integral Picatinny rail on the top of the receiver and on the additional 4 rails on the forehand.
Military / LE only selective fire versions feature full-automatic and/or 3-round burst firing modes, civilian SIG 716 rifles will fire only in semi-automatic mode. SIG 716 rifles are compatible with current Armalite AR-10 Gen.2 magazines, which are available in 10- or 20-round capacities.
