bolt stem/ guide wears out.
Dunno if this has ever happened to u guys but just wanna share a bit about what just happened to my axe.
Anyway I bought it here in used condition with boss bolt installed. Shot amazing after a bit of tuning. I swapped out a shockwave board from my mini for ease of tuning. Took it to several games, cleaned and relubed after play. Now im guessing the prev owner had the boss bolt quite recently because there is a lot of wear on the tip of the bolt guide (very last o-ring area). I didn't think it would cause any problem because so far its been working great with the boss bolt which is made of delrin.
So im getting ready to play tomorrow and aired it up last night to find that it is leaking down the barrel. So I put fresh lube and tried again. Still leaks. So I took apart the noid , cleaned and relubed but the noid is still fairly clean and didn't seem to be the problem.
Thing is if u put your finger and press it against the bolt, u will feel air coming out and put pressure against your finger. So I thought it must be the poppet face or the poppet itself which are cheap to replace.
so I went to my awesome local shop today, told them about the leak and they gave me the poppet face and brand new poppet to try out. None of them solved the leak. So I asked for a new noid but this is why they are awesome: first of, their team is shooting axes, so right of the bat one of them swapped out the bolt guide from one of the display axes. Lo and behold, the leal stopped. He then swapped out the bolt and tried my boss bolt with the new guide, no leak as well. So noid is good, bolt is good but bolt stem bad and have to get a new one.
Good thing its fairly a cheap fix for an integral part of the gun (25bux) They will have to order it from kee since I have the brown earth color. They have black in stock but id rather wait.
So just wanna put this out there just in case you are getting frustrated trying to get your axe/ mini to stop leaking only to find out your bolt guide is messed up.
