there is no "slot" as far as i can tell, its a Victory, and both of those holes it has are spotless, im positive. im also sure its not the barrel, the gun is physically not shooting as "hard" as it should. the burst of air from the breech is no where near as hard as my other guns. It seems like it has to do with the marker, not the barrel. Are there any other orings that i should check?
