posted on April 1, 2020

New from SIG Sauer is the 716i Tread AR-10 pattern rifle, which combines the reliability of SIG's lightweight direct impingement system with the customization and features of the SIG Sauer Tread line of rifles. Chambered in .308 Win./7.62 NATO and using standard AR-10 magazines, the 716i is a full-featured AR-pattern rifle that extends your reach with the power of .308 Win.

SIG has taken the proven features of the SIG516 rifle and applied them to the potent 7.62 NATO round. The 716i Tread features a direct impingement operating system, along with an M1913 Mil-Std rail, a free-floating barrel, an aluminum forend with multiple M-Lok slots and a six-position Magpul telescoping stock.
