Is direct gas impingement for your AR something you would like to avoid? If that is the case, Ruger has some good news for you! Instead of relying on gas to eject rounds, the new Ruger SR-762 instead utilizes a piston.
There are many reasons why many prefer to leave direct gas impingement behind in favor of a piston mechanism. For one, in the words of those who are piston-addics, will give you a cleaner gun that does not require heavy solvents to clean, which means more time spent enjoying your shooting as opposed to taking things apart and putting them back together, something with which a chromed bolt and bolt carrier also help. Through utilization of a piston, it is also possible to get positive ejection and an overall more reliable gun while running cooler at the same time. All of these are valid points for choosing an AR-10 with piston action.

It is likely the arguments mentioned above that led Ruger to introduce the SR-762. You known how Sturm and Co. love to give the people what they want. This piston-driven .308 is modeled in large part after its predecessor, the SR-556, which also features a piston-powered operating system. The SR-762 is a larger version of the SR-556, weighing in at 8.6 pounds, and is chambered in 7.62x51mm NATO (more or less .308 Winchester).
Don't let the weight worry you, however, as it is still light enough to carry despite the higher numbers on the scale.
Some of the other features on the SR-762 include a lightweight aluminum hand guard with comfortable gripping ability. Also present is a telescoping M4 stock with 3.25-inches of extension. The SR-762 has been drilled in all the right places to add accessories, such as rails at three, six, and nine o'clock. Outfitted with flip-up combat sights, you have a backup in case of optics failure. The cold hammer-forged barrel is fluted and 16.12-inches in length. The flash suppressor is threaded with 5/8-inch 24 threads, so you can remove it and add a suppressor of your own with ease as long as the TPI is right.
The front sight allows for elevation adjustment with the rear sight having two aperture sizes, those being large and small, and being windage adjustable. This enables successful shooting at both short and long distances with a simple rotation. Iron sights can be accessed at the press of a button, at which point they raise and are ready to go. Trigger pressure on the Ruger SR-762 hovers around six pounds, which might come across as stout to some shooters, but is not enough of a deterrent to turn people off to the SR-762.

When you purchase the SR-762, Ruger is currently shipping these with a zippered carry case. This has space to hold magazines and rail covers in its interior pouches. When you are not using it for storage, it can be unfolded to double as a shooting mat upon which you can rest and shoot comfortably (or at least more comfortably than laying in the cold wet mud.)
With so much good to say about the SR-762, there has to be a drawback somewhere, and that could be the price. It is actually priced higher than some of its competitors at a retail price of $2195.
Despite the price, the bottom line is that you get what you pay for, and in this case that is a piston-powered AR-10 with many beneficial features that very well may blow the competition away in your eyes.
With that in mind, are you shopping for a piston powered AR-10? Is the SR-762 on the list of those you might bring home? Let us know in the comments.
