The HX-QD 556K uses the proven baffle-free Flow-Through technology that directs expanding gasses away from the bore-line. This unique system routes the gas through the coil and deflector then out the muzzle, resulting in sound level and blowback reduction.
The QD-556K offers Flow-Through design with hearing safe sub-140s dB, zero flash performance, full auto-rated, zero minimum barrel restrictions and easily passes USSOCOM's reliability stress test.
