Re: Gbbr agm mag valves

Put them under water and look to see exactly where on the valve the leak is. If they're leaking from the threads, a little ptfe tape should solve that (but be careful not to over tighten them as you can rip the valve clean out of the threads).

Links wise, if zero one don't sell it then we can't link to it.

Re: Gbbr agm mag valves

are you sure that the leak is caused by the actual valves being broken, and not just o-rings needing to be relubed. Under forum rules we cant mention other airsoft retailers

Re: Gbbr agm mag valves

Here is the difference between an AGM valve (right) and a Big Dragon valve.

The design of the AGM valve is just pants, as the pressure is exerted on the spine of the valve, and gas seeps between it and the valve cap, blowing out the O-ring beneath. As you can see, the other one is a solid cap, which solves the problem.

I experimented with various different O-rings to try to repair the original, but it doesn't work – best to just import some new ones. The AGM takes a WA style GBB M4 valve.

I don't know if the Big Dragon ones are necessarily the best, but they do work, and can be found by doing a Google search for stockists with the following code: BD-GBBPT-BD8163
