The **SR-762** is a semi-automatic [AR-10 style rifle](/source/AR-10) that was manufactured by [Sturm, Ruger & Co.](/source/Sturm%2C_Ruger_%26_Co.) from 2013 to 2018. It is short-stroke piston AR-10, using a similar AR-18 type system than of the original [Direct Impingement](/source/Direct_impingement).[2]

## History

Ruger announced on October 17, 2013 on the SR-762 being produced.[3]

By 2018, Ruger had discontinued the SR-762 (along with all of the SR-556 models), as the [AR-556](/source/Ruger_AR-556) began replacing all SR-556 rifles.[4]

## Design

It comes with a patented [chrome plated](/source/Chrome_plating), two stage piston with multistage regulator provides a cleaner, cooler running, reliable firearm with superior operating endurance. Two-stage piston provides a smooth power delivery stroke to the bolt carrier. The round, smooth-sided ergonomic Ruger Lightweight Adaptable handguard with flattop receiver features a Mil-Spec 1913 Picatinny rail at the 12:00 position that extends the full length of the handguard. Drilled and tapped for additional rails at the 3:00, 6:00 and 9:00 positions, offering ample space for mounting sights, lasers, lights and other accessories. There are two additional rail sections included. Folding backup iron sights include a windage adjustable rear sight and an elevation-adjustable front sight. These sights provide a solid aiming system that can be folded out of the way to make room for optics, yet instantly redeployed when duty calls. For accuracy and longevity, the cold hammer-forged 41V45 chromemoly vanadium steel barrel has been precision-rifled and chrome-lined. Barrel is fluted for reduced weight and improved barrel-cooling and features an SR-556/Mini-14-style flash suppressor mounted with a 5/8"-24 thread. Chrome-plated bolt and one-piece bolt carrier with oversized and radiused-rear bearing surface. Six-position telescoping M4 style buttstock is mounted on a Mil-Spec diameter tube. Hogue Monogrip pistol grip. Includes three 20 round magazines, soft sided gun case and three finger-grooved rail covers.
