The Ruger SR-762 is a piston-driven 7.62mm NATO powerhouse. In the upcoming February 2014 issue of Special Weapons for Military & Police, author Dave Spaulding writes, “The 7.62mm/.308 has long been the round of choice for law enforcement countersniper operations. Powerful and accurate, the 7.62mm was the chambering for Eugene Stoner’s original gun, but the military wanted something lighter with greater ammunition capacity, so the gun was re-chambered for the 5.56mm NATO… However, the 5.56mm is not known for its ability to penetrate vehicles and other likely barriers, so interest in the 7.62mm is high among American law enforcement agencies and officers.”

And while 7.62mm-chambered ARs are nothing new, the Ruger SR-762 certainly is. Luckily, Spaulding got his hands on one and delivers his full range report. He writes, “Like the SR-556, the Ruger SR-762 is a piston-driven gun, a platform many prefer due to its ability to run cleaner and cooler. Since discharge gases are not vented directly into the gun’s action, as with direct gas impingement systems, crud buildup is all but eliminated. Ruger’s patent-pending, two-stage piston design delivers a smooth piston stroke to the one-piece bolt carrier, which reduces felt recoil and improves the rifle’s durability. A four-position gas regulator allows the shooter to tune the rifle to function reliably with a broad variety of ammunition and in varying environmental conditions, including with the addition of sound suppressors.”
