If you've ever shot a suppressed AR chambered in .308 Win., one of the immediate effects you'll remember is the gas blowback that travels through the charging-handle cutout and into a shooter's face. Radian Weapons has a solution for that in the form of its Raptor-SD Ambidextrous Charging Handles. Where the Radian Weapons Raptor-SD Ambidextrous Charging Handle differs from traditional designs is in the inclusion of a ported shaft that shifts gas flow down and forward, in the opposite direction of a shooter. The ambi design of the handle also allows for rapid charging by blading the handle with either hand in one fast, fluid motion. Each Raptor-SD Ambidextrous Charging Handle is machined from 7075-T6 aluminum and is designed and manufactured in the USA.
