You breach, shoot a few rounds and then can't hear feedback from your team because you're temporarily deaf from the concussion and blast noise from your muzzle device. The Fortis Control Shield was designed to push the noise forward for combative situations or even for simple range use, while the top ports keep the muzzle device flat on target. The patent pending quick detach system will be made available for other manufacturer's to use in conjunction with their muzzle devices. So whether you're knocking down doors or shooting at the range, let's help save your hearing. So click on the Control and go!
