Hi, I've really got my eye on this gun, the S&W M&P15PSX:
I have some questions about piston system AR's.
S&W lists the weight of this rifle at 6.5 lbs, which is the same weight as the comparable models that use the DI system. How is this possible? Does the gas piston system simply re-locate parts that were originally inside of the reciever to a different location?
I realize that the piston is contraversial, and AR purists will say it's not necessary, but I like the prospect of added reliability, cooler temps, and easier cleaning that the piston offers. This gun uses a factory-installed adams piston system. Are there really any drawbacks to the piston system other than cost and parts commonality with other AR's? I have heard some say that it decreases accuracy, but that seems debateable.
