    Competently made rifle. Works, is accurate, and reliable.

    For semi-auto fire, the gas system is not necessary. However, it will keep the bolt cleaner. Drawbacks are non-compatibility with mil-spec parts. You will be beholden to Ruger for spare or replacement parts for the gas system and bolt. And these parts are not compatible with other piston style gas systems. Another drawback is weight. This type of a gas system weighs more than a direct impingement system. "Lightweight" is not a compatible word with "SR-556".

    Also, for those using a suppressor, it's a two-edged sword. It helps keep the action cleaner, but the drawback is it is not as quiet as a suppressed gas impingement system (stock AR15). This is because the gas directed to the gas system is vented direct to the atmosphere and will make a loud pop.

    Price is another issue. The Ruger is not cheap, and you can get a model with a four railed free float tube cheaper with money left over for optics and accessories, or two plain AR15s. (Except for the SR-556E model, which is actually attractively priced for a gas piston system. Note that additional rails can be added later to the E model.)

    But again, I cannot find fault in the product itself. It works.

    In a recent issue in Guns and Ammo Magazine Patrick Sweeney did a torture test on a bunch of AR's including the piston guns. They didn't fare one bit better than the standard configuration AR's.

    Exactly. That's because the only real advantage to them is for full auto fire. And even then the standard gas system is not a big problem.

    The only application where a gas piston system "may" be a benefit is when ultra short barrels are used in Sub Machine gun versions. The timing is totally out of sync with the pressure curves on the short barrels and the result is rapid bolt and carrier failure.

    The Gas Piston was developed along with the earlier AR's and is nothing new or revolutionary...The military has deemed it best to not employ it in the field...It's recent resurgence is nothing more than a marketing ploy to increase sales.

    No carbine barrel or longer, will benefit from it......And unless your gonna burn thousands of rounds of ammo a day, in a AR/SMG the average user will never see the difference.
