It's a total SIG setup: rifle, ammo, suppressor and optic—all made by SIG Sauer. The most significant change to the Gen 2 716 rifle, introduced at SHOT Show 2017, is that it is now available in 6.5 Creedmoor. Other notable changes include a one-piece M-LOK handguard and a PRS Gen 2 stock for more adjustablity, and overall weight is much lighter at under 10 lbs. Icing on the cake for this chambering is a new SiG 140 gr. cartridge. For more, seeAmerican Rifleman's Joe Kurtenbach fire the rifleat SIG Sauer Range Day 2018, and visitsigsauer.com
