The Walker's Razor Tacti-Grip Electronic ear muffs are ready for the range. The silicone composite headband holds the Tacti-Grips in place during rigorous range sessions and allows you to wear the muffs during long range sessions in comfort. Made of a durable sound dampening composite housing, the Tacti-Grip provides a noise reduction rating of 23 NRR. The sound activated compression is 0.002 seconds to ensure your hearing is protected. The two hi-gain omni-directional speakers pick up ambient noise and broadcast it through HD speakers for ultra clear sound. The low-profile ear cups are ideal when shooting longs guns because they are less likely to interfere with the stock. An over-the-ear muff is preferable for indoor ranges as well. Protecting your hearing is very important so Walker's makes protecting your hearing easy.
