The Aero Precision BREACH® is a rugged, ambidextrous, precision-manufactured charging handle for the AR15 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.

The large lever configuration provides an extended operating surface, perfect for a user with bigger hands, or someone who wants a larger surface for manipulation of the charging handle.
