The AR-556 Brass Catcher provides a unique and effective way to control the throw of ejected brass casings during firing for safety, cleanup convenience and reloading support. It catches approximately sixty .223/5.56 casings before needing to be emptied. The Brass Catcher mounts quickly and easily to the rifle's Picatinny Rail with two slide-on, slide-off attachment rails. It allows for two-position mounting (high or low) and can easily be custom-fitted using common hand tools so the catcher will not obstruct or interfere with other items that may also be attached to the rail. The Brass Catcher is made from strong, lightweight, black textured plastic. Made in the USA by E&L Manufacturing.
