Extra back barrels for different size paintballs and temperatures.
Reliable, easy maintenance, air efficiency.
Rammer's Oring worn out fast. Hard kick, Zick2 make it better.
I've been using the Ego9 for almost a year now and never have any issues with it. This great marker never chopped on me; there are really really rared occasions that the paint break in the barrel( I think the reasons are: bad paint quality and improper barrel back size). The reasons they introduced barrels back kit are to accommodate different paint sizes (there are lots of different sizes out there-from the sh!tty Monster Ball at Walmart to RPS Marballizers) and deal with various temperatures. In general .693 would take most paintballs but if you want the accuracy you would want to measure the paintball size to the barrel back (too tight-ball will break, too loose-no straight shot). In extreme hot temperature paintball swells up a little so a larger back barrel size will help. In extreme cold temperature paintballs sometime become fragile so a size up would help too. Anyway, those are different issues, thought that might help someone in general. Back to the subject, I think the Ego9 is going to last me for a long time (of course I have to keep up with the maintenance).
Ego9 is one of the greatest marker up to date with a couple of minor problem.
9 out of 10
