Hello, apart from a few videos, there are not many katran tests on the internet.I am interested in the LB .22 (long with bottle) model and I would like to know how much battery life it has.Initially I wanted to take a Uragan but I find the look of the Katran nice.I have an FX impact MK2 and I would not like to be disappointed by airmaks which is new on the market.If anyone has any personal feedback I'd be interested.Thank you
