The Radian Raptor SD ambidextrous charging handle is based on the same design as the original Raptor but is optimized for use with suppressed weapons. The new patent-pending design features a ported shaft to redirect gas and minimize blowback, which results in a much more comfortable shooting experience. Made in the USA from aircraft-grade 7075 aluminum and Mil-Spec anodized.
