Geissele Automatics Airborne Charging Handle, Low Profile Lever Design, 7075-T6 Aluminum, Ambidextrous, Black Finish, Fits AR 15 05-497B The Airborne Charging Handle (ACH) was developed at the request of an elite organization famous for its expertise in aerial insertion. The organization requested a lower profile lever design to reduce the chances of snagging. The ACH's lower profile design is especially ideal for rifles where the primary sighting system is a red dot or similar low profile optic system. The ambidextrous ACH is 3D machined from a solid block of aircraft grade 7075-T6 aluminum. Shortened levers are dual contoured with gently concaved radius cuts in the vertical and horizontal planes. The handling surfaces of the levers are checkered for confident operation while wearing gloves. A taller fence at the rear of the ACH aids in redirecting gas blow back when shooting with short barreled and suppressed weapon systems. The ACH and its components are Type 3 Hard coat anodized and are available in Black and DDC (Desert Dirt Color).
