SIG Sauer's four AR-10 type SIG716 tactical rifle line will arrive in three barrel lengths and arrives with a fully automatic mode for law officers.
Chambered in 7.62 X 51 mm (.308 Winchester), the SIG716 tactical rifle line are gas-piston operated with a three-position gas valve (four-position optional). This design keeps the receiver free of firing residue for optimum reliability under adverse conditions and extended firing.
The SIG716 select-fire modes include single-shot, three-burst, and fully automatic (for law enforcement only). The fire control/safety selector is an ambidextrous design to improve accessibility and safety.
Four models include the SIG716 12.5-inch-barreled Tactical Patrol, the SIG716 16-inch Patrol, the SIG716 16-inch Precision Marksman and the SIG716 20-inch Precision Sniper. All models arrive with a free-floating, aluminum-alloy, quad-rail forend with four M1913 Picatinny rails for lighting and laser-mounted options.
Barrels are chrome-lined for extreme durability and corrosion resistance. The Precision Marksman and Precision Sniper models feature a muzzle that is threaded with a standard (0.625x24TPI) pattern to accommodate a wide variety of flash suppressors, muzzle brakes and sound-suppressor devices.
The lower and upper receivers are machined from aircraft-grade aluminum. Back-up iron sights are standard.
