The folks at Sturm, Ruger have added yet a new completely new firearm to their rapidly expanding catalog. This one is a piston-driven, short-barreled modern sporting rifle. Chambered in 7.62x51mm NATO, it\'s a heavy hitter.

In their press release, Ruger calls the SR762 \" ideal rifle for those who appreciate the familiar and ergonomic AR-style platform. The .308 Win./7.62 NATO cartridge is perfect for hunting medium and most large-sized game and enhances the capability of the AR-style platform in defensive or tactical roles.\"

Taking a look at it, the SR762 has just about every feature you would want in a 7.62x51mm NATO battlerifle:

Piston standard

The rifle is piston-driven from the drawing board rather than direct gas impingement. Its chrome-plated and two-stage with a multi-stage regulator that provides a cleaner, cooler running, reliable firearm with superior operating endurance. The two-stage piston provides a smooth power delivery stroke to the bolt carrier. While Eugene Stoner\'s original AR platforms were always direct gas impingement, it should be noted that some of the world most reliable combat rifles, including the legendary M1 Garand, are gas piston-driven.

The piston system is inside what Ruger calls its Lightweight Adaptable hand guard. This features a Mil-Spec 1913 Picatinny rail at the 12:00 position that runs the length of the entire hand guard from rear sight to front. Drilled and tapped for additional rails at the 3:00, 6:00 and 9:00 positions (two additional rail sections included), you should be able to mount just about any optic, light, laser, can opener, chainsaw, or ZiP22 that you want.

Fluted barrel

The SR762 is a large-caliber rifle compared to a standard 5.56 gun. As such, it has a 16.12-inch precision-rifled, cold hammer-forged Mil-Spec 41V45 moly-vanadium steel barrel. Chromed for your cleaning ease, it fully fluted which cuts down on weight while speeding up cooling of the bore. Twist rate is 1:10 to help stabilize the wide array of 7.62x51/.308WIN cartridges.

At the end is a threaded muzzlebrake that can be screwed off to allow mounting of a harmonic balancer (think BOSS), custom break, flash hider, or suppressor. Speaking of chrome, the one-piece bolt carrier and bolt are also chromed as well as having oversized radiuses at the rear-bearing surface.


While the rifle comes standard with a full-length Picatinny rail to make optic installation a snap, it also has a front and rear folding backup iron sights right out of the box. While you can buy MAGPUL MBUS sights aftermarket for $90-ish, it is nice that Ruger is including their own version as standard. Thiers are windage adjustable (rear sight) and an elevation adjustable (front sight) to get that good battle-zero should your optics fail.

Other features include a Hogue mono-grip, sight adjustment tool, manuals, three 20-round Magpul mags, a soft case (with a Ruger eagle of course), and rail covers. A six position M4 style buttstock is standard, but it\'s on a mil-spec dimension tube which helps if you want to change out over to another system.

Sadly, it has a suggested retail price of $2,195. Apparently, you have to pay to play in 7.62. Hopefully as these prove more popular they will drop slightly. As it is, you can get into a range of Springfield M1A and Armalite AR-10 rifles, which will be SR762s main rival, for about $1500-ish wholesale.

This could prove interesting. Watch this space for updates.
