No luck on my end. When I first got my eigen bolt i used a microfiber cloth and some Sp sleek and hand polished the bolt, hand fit the orings for a nice fit. I shot maybe 2 hoppers adjusting dwell and input pressure. Got it all figured out shooting decent and put it away.
After that i shot a hopper full of reballs just goofing around. I then had company over and let them shoot a hopper with my shocker again just goofing around. well about half way through the hopper i could hear it developing a leak. I then stopped and decided to see what was going on.
Starting taking everything apart then noticed this on the bolt guide. The bolt guide o-ring supplied with the eigen have swollen and one actually has broke.
So far I'm not very impressed overall. I guess now i will wait for someone to find the magic o-ring for the bolt guide.
