FX Monsoon Blown O-Ring Repair

Hello - I seem to be having a problem with my Monsoon - sometimes (on a full full) it won't cycle 100% of the time, I think it's a blown o ring.

How hard is this to fix, I've never taken apart an airgun before and not handy at all. I don't want to screw up my monsoon by taking it apart.

Is there anywhere in SoCal that can check it out/fix it? Wondering how much something like that costs? Thanks in advance everyone.

you can check the breech if the o ring is not there, just cork the gun put on safe have a look, that o ring replacement do not need to take your gun apart.

Call me if you are near Huntington Beach, or Tim if you are closer to Gardena

I thought I responded to you earlier, but I guess I didn't submit the response.

I probably have an extra I could spare. Email me if you are close to HB.

don't know if these help any.

I'm willing to drive if someone can fix this thing. Maybe it's not the o ring?

If it is a .22 cal the oring is a #009. Pretty simple fix that will probably never fail if you use the good stuff. 90 Durometer urethane is the stuff that will solve the problem permanently.
That oring is supposed to be sandwiched between the brass piece and the back of the barrel which the brass piece presses over.
Sometimes the brass piece can move off the back of the barrel in which case the barrel needs to be removed and the oring replaced and then the brass piece needs to be loctited in place.
Usually something we can do while you wait depending on how busy we are.
My Shop is in Gardena. Open hours are 11-6 M, TU, F & Sat. 310-327-3581
If you replace it with a like hardness oring you'll need to get a few as they only last so long. A hard urethane oring will last for a very long time. We've yet to see any fail.
