The SIG Sauer SIG516 Patrol marks a departure for SIG Sauer from the direct gas impingement system to the ultra reliable gas piston system. As one of the most tested and proven weapon systems in the world with beyond military grade features the SIG Sauer 516 Patrol sets itself apart from the competition. With a four position gas regulator the piston drive system incorporates all the most desirable mechanical improvements of this system. Add to that a free float hand guard, collapsible stock, pistol grip and mil-spec trigger group you have a winning combination. If you like the best things in life then the SIG Sauer 516 Patrol is the rifle for you.
