Hi Im thinking of selling my E tac one x mag. I think I got the right name for it. but don't know what it's really worth it's only shot 4-5 cases of paint and it's has the xmod software Will include the board to flash new software but the battery dosent want to charge and I don't see the point of buying a new battery for a marker I haven't used in years. seen in the rare classified there was a x mag went for over 300 are the really worth that much? Any advice much apricated.
