The Dead Air SANDMAN 5.56 FRONT CAP is engineered to enhance your silencer's performance by reducing the front cap size to match your caliber. This precision design minimizes first round pop and decreases the muzzle reading by approximately 1 to 3 dB, ensuring a quieter shooting experience. Compatible with a range of Dead Air silencers, including the Sandman series, this front cap is crafted from durable 17-4 stainless steel with a black nitride finish for corrosion resistance.
