Springfield ST916556BM Saint, 5.56 Caliber, AR-15 Rifle, M-LOK Rail, 16" BBL, Black MID Length 6-Position Stock

Springfield ST916556BM: The SAINTs flat top design is optics ready and includes a flip-up rear aperture sight and fixed A2-style front. The 16-inch Chrome Moly Vanadium barrel features a 1:8 twist rate to handle a wide range of bullet types. The operation of the M16 bolt carrier group is managed by a mid-length gas system paired with a heavy tungsten buffer, resulting in an exceptionally smooth action. A good shot starts with the trigger, so that's why the Saint AR-15 features micro-polished and Nickel Boron treated components. While it offers the right pull weight for defensive use, you won't feel it.
