Good day everybody. Have any of you ever tinkered with one of these? I need to change the seal. When I put the CO2 capsule in all the gas shoots out the barrel. I always put a drop of Pellgun oil on the top of the capsule before inserting it. This is a non blow back pistol. I'm hoping to find some info on how to strip the gun down and change the seal. Also I would need to know where to find the parts. I googled and searched the internet but could not find any info.

My wife gave me this as a gift so I would really like to be able to fix it. Thanks for your help.
 
I think that's a relatively new model? Perhaps covered by manufacturers warranty? Say you got it as a "gift" (that's "for sure" well within it's warranty period check their warranty policy for this clock ticking down expiration first) unless you can dig up that receipt if it was an online purchase perhaps on a credit card statement? They will probably trade you for a brand new one if you didn't tamper with it so hopefully you didn't.
 
If you have a compressor air hose sprayer nozzle use it to blast it in as you feed that Alphabet org stop leak instead of wasting more co2s. Over do it and be generous keep blasting compressed air at it. Let sit for at least a day maybe 2 just to be sure then try another fresh co2. By blasting compressed air that may also help to dislodge any dirt or dust or particles that also may be giving problems. Report back when done.
