I've got a .410 single shot with a single bead and no vent rib that is shooting high. This is a cheap CVA gun - it's pretty much terrible, but it has some family history. There is a step-down from the receiver to the barrel of 1/4" or so, and then there is a plain barrel with a small, screw-in bead on the end. I can't even sight correctly down the top of the gun because of this step-down, so I just have to line up the top of the receiver with the bead. It shoots about 14" high at 30 yards with a normal hold or 6-7" high when I sight it so I can just barely see the top of the bead.
I would like to fix that. I was thinking of putting on a new bead, or even a fiber optic, but I need it to sit about twice as high as it is now. A high bead of some kind. I wouldn't mind a fiber optic, as most of the shooting will be at stationary targets, but most are made for a vent rib, which this gun doesn't have. I have no idea what kind of thread is on the screw. What do I need? What are my options?
