Well iv owed it for just over a year never had any problems or issues with it apart from it could do with some new ball detents other then that nothing. Not been used for 4 months since I got my ego. And yeah the barrel on its an early shaft not sure what one tho with a e star tip no wear on the barrel a part from a tiny bit on the tip. And yes I t is a internal pop it but it is a very quite and smooth shooting gun. Anything else you would like to knowEver had any repairs whilst in your ownership? How long have you had it for? And what barrel is that? A shaft of some description as that is estar in it I believe. And is it an internal popping like a victory?
