Hi, hope all good. To be honest I'm zero when comes to this upgrades. There's is any chanse to send make a video on YouTube to help me to sort this? I really want more power on the gun. Thanks
So when you say inlet, is the co2 inlet or where the hammer hits ( the blue circle ) ? The Ideia is to increase the volume capacity correct? Many thanks for your support
The inlet on the valve is right after the first pic you sent. The goal is to allow more gas to get through for each shot. Also bumping the hammer spring tension helps a ton.
Hi Joeyjohnson, thanks for a very informative post. I have a Sig M17 which has just started leaking thru the valve in the magazine so I need all the orings and the nylon washer in that valve. Do you know where I can find them? ALSO,I have not opened up the gun to see the valve you are talking about but do you know if the same mods would apply to the M17? Thanks again...jim
For the nylon c02 washer, these usally don't go bad. They can get scuffed up or dirty. Usually I take them out. Sand with some fine wet sand paper just to clean up any dings and then clean really well. Then use some gun oil when you install the c02.
As for the valve, I have not been inside this exact model but they all function in the same manner so yes the mod should work fine. Let me know if you have any questions.
No you will not have to take the handles off. Just open the back and then take the c02 out. For the pin, yes it is in the fake take down lever. #50 in your diagram I believe. Thanks for the info on the MCX.
As other members have said, thanks for sharing your work on this. Have just bought one of these and looking to carry out the mod you've highlighted. What's the best way of removing that pin on the dummy take down lever? The reverse has a straight cut away edge to it so was wondering if it has to be turned to release it?
New to the forum, glad to have found an outlet for my creativity. I have the MPX. Can I assume the above MCX diagram will be similar enough for disassembly? Also, which mod would you consider the most beneficial for velocity increases; HPA kit or valve porting+spring change?
