I'm having problems with my Tippmann 98 Custom. After not using it for about a year now I was going to take it out again and start using the new D-Mags in it. Problem is now when I try shooting it it will not recock correctly. Tried everything I could think of to get it going again. New main spring, messing around with the RVA I had on it, even swithcing back to another stock and removing the sealed bolt kit. Nothing seems to help. Any ideas would be welcome. Hoping to get it working again for a big game this weekend.

Ok so this marker of mine has leaked far too many times for me to count now. I've replaced at least 3 different o-rings(one of which twice) and it still wants to leak once I start shooting. Am I just not using enough lube or am I missing something bigger. The leak is coming through the front of the bolt and I can sometimes air it up (it seems fine) but then I take one shot and its f***ed. Can anyone help?
