RRA LAR-8 Charging Handle


RRA LAR-8 Charging Handle

These are designed for RRA LAR-8 models only.


Geissele Airborne Charging Handle


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.

Optimizing the contours into a snag-free profile that facilities immediate manipulation with and end user’s reaction side grip.
