Guarder Extreme Output Valve for Marui Hi-Capa 5.1

1 Customer Review

by David S. on 12/23/2009
"Pretty simple part on the whole. I was rebuilding my We-Tech 5.1 7inch and needed new valves for the magazines. My brass stock valves blew there o-rings during some cold weather.

Great product, easy to install, I recommend using a thread sealant during install to make sure of a tight fit. If you have a valve key (they sell that here) it makes it easier. Carefully when you install it though. It'll need to be tightened down to the point where your concerned about stripping the threads. When you get it tight enough that your worried about (for me anyways) that's about right.

If you can't afford a key, it's fairly easy to make one out of a old large headed flat screwdriver. I did it with a grinder and made mine (then I bought a valve tool later on) it works okay, but takes a lot of pressure to keep from slipping.
