Styled after the Flash Hider for the M16A2 family of weapons, Muzzleshot, dubbed as “The Tactical Shot Glass,” is mil-spec hardcoat anodized aluminum shot class and rocks glass. With options to buy the shot glass on its own, as a pair, or as a pack of 4 that comes in an SKB 3I Series injection molded mil-standard waterproof case, there is no question that the Muzzleshot definitely makes for a great and unique gift.
