Familiar handling, unfamiliar power, SIG SAUER has taken the proven features of the SIG516 and applied them into a potent AR-based rifle chambered in 7.62 x 51mm. Utilizing the short stroke piston-driven operating system, an M1913 Mil-Std rail, free-floating barrel, aluminum forend, and telescoping stock, the SIG716 is the rifle of choice when you require the power of a larger caliber carbine.
