The Battle Arms Development Rack Ambidextrous Charging Handle was designed with a revolutionary new mechanism which is unlike any other charging handle on the market. The weakest point in most charging handles is the roll pins. The Rack was designed without roll pins. A new patented latch system slides parallel with the receiver notch for slick and quick release and simultaneously minimizes wear. The Rack was designed to be able to be charged quickly and smoothly from either side. Precision CNC machined from billet 7075 T6 aircraft grade aluminum for strength and light weight and coated with a hard anodized black finish. Made in the USA.
