OK, just got my new bko, loved it first time i played. However when i was all done playing i noticed that one of the allen scews on the back of the marker was missing, while the one on the opposite side was loose. The scewes i am talking about are on each side of the marker, all the way in the back below the bolt. It seems like they hold the electric sear in place inside the gun. When I tightned the remaining screw i noticed that I can no longer slide the bolt back and forth smothly, it gets very tight toward the rear of the gun. IF i take the screw out it slides with ease. Any suggestions or help would be greatly appriciated.
