Aero Precision BREACH, AR-10 Charging Handle, Ambidextrous, Large Lever, Gas Deflection Shelf, Anodized Finish, Kodiak Brown APRA700341C The Aero Precision BREACH is a rugged" ambidextrous" precision-manufactured charging handle for the AR10 platform. The BREACH's design utilizes a reinforced 7075-T6 aluminum bar that is up to the most demanding tasks. Its ambidextrous levers feature a patent-pending" dual spring system" that directs the force-of-use into the robust charging handle body. This allows the shooter to use a one-sided charging technique without compromising the part - a pitfall for traditional mil-spec charging handles.
