SIG's 516 is a short-stroke gas piston AR, and the piston system is the whole argument: it keeps combustion gas and its carbon out of the receiver, which means a cleaner-running action and noticeably better behavior when suppressed or when running hard without cleaning. This Generation 3 rifle carries a 16-inch barrel in 5.56 NATO with a free-float M-LOK handguard and a black finish, sold as a Freedom Package configuration. It is a well-built duty-grade carbine for home defense, training, and general-purpose use, with all the AR-15 aftermarket support you would expect.
