the bbs jams before touching the hop up. With the hop up removed from the gun, the bbs still jam. With a LOT of force with the cleaning/unjamming rod, i can push the bb past the stuck part and out the flash hider end of the gun. If I push the bb with the cleaning/unjamming rod toward it's origin, there is no resistance and the bb unjams no problem. I drew a picture in paint as to where the bb jams. It jams in the rubber sleeve.
