Max Tactical developed the Guardian Tactical Muzzle Cap to keep dust and water away from the inside of barrels. Since there is an issue muzzle cap that costs about ten cents a piece, one wonders why a company would develop a product to do essentially the same thing for 50 times the money. The reason is actually pretty simple. It does it better, and it does it on a wider variety of flash hiders than just the M16 family birdcage.
First and foremost, the TMC prevents dust and water from fouling the barrel. It also does a better job of protecting both men and equipment from damage caused by an inadvertent barrel tap while riding around in armored vehicles. Manufactured from non-toxic TPR (Thermal Plastic Rubber), its unique design allow you to remove the cap from the muzzle while keeping it attached to the barrel. The four ribs are flexible and the cap will hang out of the way below the barrel when not in use. However, for high rates of fire (in excess of three magazines) the TMC will melt. Designed to fit to most NATO rifles including the M16/M4 series, FN FAL, L85 Series, AUG, M249 Series, G3, G33, G36 Series, and Famas. When not removed before firing, the TMC will fly 10 – 20 feet and the thin material at the muzzle will not alter accuracy at 50 yards. One of the major deficiencies of the issue cap is that the remnants can be difficult to remove, especially after it has been expended whereas the Guardian TMC’s body and material provides a solid grip even when hands are wet.
