Holding true to the original's sub-MOA accuracy, right out-of-the box, the second generation SIG716 DMR features an improved gas system, lightweight handguard, and an overall weight reduction of more than two pounds. The two-stage match trigger and muzzle brake help shrink groups to less than a single minute-of-angle, accuracy simply thought impossible from a gas piston. This two-position adjustable gas system keeps carbon, excessive heat and other fouling out of the chamber, enhancing reliability and accuracy. Chambered in 7.62 x 51mm, the SIG716 DMR G2 works well with any model suppressor or muzzle device.M.
