The KX3 is the biggest scam of all time that preys on people lack of understanding of the AR system ( or people with s**tty AR that is not done correctly)
Increasing the duration of the pressurization is not going to help if the volumetric flow of gas is calibrated correctly with the correct gas port size. Just because the AK Krink gas system is designed to use a muzzle device to prolong the pressure duration, it doesn't mean the AR needs one - and that the system is calibrated to use such a muzzle device, not as an after thought. Basicly you are just slamming the door open, after the door is open, you keep pushing the door against the wall.....
