looks rubbish. i bet it will never take off. It says it could be used on sites instead of paintballs, butby having that barrell on your marker, it isnt painball. paintball is were you shoot balls of paint at each other, hence the name. fair enough saves money and everything but just doesnt look very fun. And then you have to gas up each time anyway, if the gas were used to fire something then ok, but it doesnt. just comes out the end. i would just use reballs, much much better
