Hi I was wondering if anyone could help, I have an Ego 9 which had velocity spikes this weekend. I chrono’ed it several times though out the day. It was spiking between 276- 285, then on occasion spiked to 299-315. I did several barrel changes trying several bore sizes as I thought it was a paint match issue even with the 693 it spiked... When I got home last night I stripped the gun down and found that one of the rammer o-rings was split down the centre. I have look on the PE web site for a spares kit for the Ego9 and can’t find one. Does any one know where I can get replacements? And how I can stop this from happening again?
