The silencer-optimized Raptor-SD™ features a ported shaft designed to redirect gasses down and forward, away from the shooter’s face when shooting suppressed. Its ambidextrous design allows rapid palm "blading" or finger-thumb charging of the weapon, ensuring the motion is fluid and fast from either strong or support side. The Raptor-SD is compatible with most AR15/M16-pattern rifles. This product is designed and manufactured in the USA and machined from 7075-T6 Aluminum. Popular models compatible with the AR10 charging handle includes: Aero M5, STAG-10, Armalite AR10, Knights Armament SR25, Daniel Defense DD5 V3, V4, V5, DPMS Gen1, and many others.
