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. • Designed & Manufactured in the USA • Machined from 7075-T6 aluminum • Milspec Type 3 Hard Coat Anodized Finish w/ Cerakote Color Options
