It came as a surprise several years ago when SIG Sauer introduced a direct gas impingement system AR-style variant, the M400 semi-automatic-only carbine, which has some distinct external and internal differences from most AR-style rifles. You can learn more about the M400 in this "Rifleman Review" segment from a recent episode of American Rifleman TV. For more videos like this, visit AmericanRifleman.org/artv.
