HK Army Rapid Fire Valve

I love it not as fast as my electric but its good for people on a budget that want to keep uo with electric markers highly recommend

The upgrade is simple. Using. The video you provided to install was easy and worked like it should. Easy upgrade for my emec 100 from a mechanical semi auto marker to mechanical auto.

Used for one game and had to switch back to the stock valve. It was double feeding my paint like crazy even with a pretty decent hopper. It does what it’s supposed but becomes hard to single fire.
