The KET Brass-Deflector is a new, patent-pending brass catcher alternative. Built tough, lightweight, and heat resistant, our products allow law enforcement, shooters, and reloaders to keep spent brass close for easy cleanup, without weighing down your firearm or interfering with moving parts and optics. The simple, snap-on installation takes only a moment—with no mounts required—directly on your AR scope or Picatinny rail.
