The Airborne Charging Handle is 3D machined from a solid block of aircraft grade 7075-T6 aluminum. Its ambidextrous design allows for seamless operation from either side of the weapon. The levers are dual contoured similar to that of the charging handle of an M14, where not only the x-axis but also the y-axis receive radius cuts. The handling surface of the lever is also checkered, adding a textured grip aiding to the use when operating with gloves. The heightened rear lip of the ACH aids in mitigating gas blow back to the shooter when shooting with short barreled and suppressed weapon systems. The lower profile lever design of the ACH reduces chances of snagging on gear. All parts are then Type 3 Hardcoat anodized.Airborne Charging Handle 5.56 (ACH(R)) - OD Green NotesANODIZE VARIATIONS & DIFFERENT LIGHT SOURCESYou will notice that some of these will have wildly different shades of colored anodizing, and they look wildly different depending on the light source! Why would we even consider selling parts like this? The answer is there is absolutely nothing we can do to make colored anodizing consistent for the superior type of anodize used.NOTE: In the images above you will find a collection of these parts to show you a range of what you may receive. Also shown are images of the same exact parts taken under different light sources. For more information, please refer to Geissele's website Here.
