Okay, so my sm5k worked fine and for some reason it quit firing. I opened it up to see what the problem was and I found that the notch on the end of the valve pin has been worn down, I found the o-ring over the notch because of this, therefore the gun won't fire. All the other parts are in great condition, but without that, it can't do anything. Any ideas on how I might be able to fix this?

Here's a Picture...not sure it'll help much.



All help appreciated,

Hm, the only o-rings I remember in the SM5k are INSIDE the chamber. Did you actually take apart the chamber itself? Because the notch inside the chamber just doesn't make any sense- the chamber I've opened up has no such notch.

Now, if you're talking about the firing pin that attaches to the trigger, you could try this mod, which bends the firing pin, which bypasses the original trigger system entirely. Good luck!

Thanks, I ment the firing pin...bad mix up on my part.

Then I'd suggest following ompa's advice and doing the tank relocation mod. The best part of that mod is that it gives you a direct mechanical connection between trigger and valve rather than that spring loaded thing.
