Its unique shape and the process of its manufacture—3D printed from heat-resistant nickel/chromium-based Inconel metal alloy—make the Neutralizing Energy, Remain at Origin (NERO) 556 Tactical muzzle brake by Walker Defense Research an unusual, yet effective, entry in the crowded arena of muzzle devices. The U.S.-made brake, which is designed to reduce felt recoil, minimize muzzle climb and manage felt concussion, is currently manufactured for 5.56x45 mm NATO (.223 Rem.)-chambered firearms. It is threaded 1/2x28 TPI, comes with one crush washer and is Black Cat PVD-coated and serially numbered. Price: $180. Contact: Walker Defense Research, LLC; (602) 680-3310; walkerdr.com.
