TAP Patrol is specifically designed to provide consistent and reliable performance through the FBI protocol when fired through 14.5" – 16" barreled 1:7 – 1:9" twist patrol rifles. The lead free GMX bullet features a flat polymer tip, which allows it to provide “barrier blind” performance ensuring consistent penetration depths.  The flat tip design ensures the bullet will not plug with material from the barriers and ensures feeding through the wide variety of patrol rifle platforms. TAP Patrol ammunition is loaded with temperature stable, low flash propellant designed to work when you do.
