The FM15-223-G2-16I-2FTT is a semi-automatic rifle chambered in .223 Wylde, chambering, and firing both .223 Remington and 5.56 Nato flawlessly. At first glance, it may appear to be an AR- Type rifle with it’s buffer tube stock, but that is simply not the case. With it’s unique internally captive recoil system, it can fire with a folded, or an extended butt stock, unlike an AR15. This allows you to shoot from a compressed position or a deployed position
