I think I can help explain this away as I am a friend of Pauls.
At time of buying, from what I remember Paul saying, Just Paintball were out of 09 frames or something like that (there had been a problem, I'm not 100% as it was a passing comment a while back) Anyway it is an Ego 10 frame on this 09. Paul did not do this, it came like this from Just Paintball. He has not upp'ed any of the parts so has standard bolt, and all other parts are stock.
I have shot and used this marker a few times and it fires like a dream! Soo much lighter, softer and better than my 06 Ego.
I'm quite sad to see him selling this
Hope This Clears Everything Up
Thanks
