13xx plastic breech sights and sight mods

[stonykill]

 ok, here is what I did to the stock rear sight. I shaved a lot off of the top rear portion. Having the metal v notch even or lower than the plastic caused double images.

  I also made the adjusting slot in the blade longer to get it low enough. Nail polish shown here and on a dot on the front sight.

   

   I also sanded the base of the rear sight to get it low enough. Didn't measure how much but I did it on a random orbit sander and it was enough removed that in order to get the rear sight to sit level I needed to shave the top of the rearmost round portion of the plastic breech. Sorry for the bad pic.

   Probably took an 1/8th of an inch off of it.

   

   Now at random ranges to 20 yards I can shoot a hickory nut off of a tin can every time. And shot this group yesterday afternoon, just over 5 meters (17 feet exactly) offhand with my right shoulder on a door jam. I'm left handed. 5 shot group at 5 pumps. All in one place except for one which was 100% my fault.

 

   So until I place my next Crosman order and pick up the 2 Bill suggested, I'm pretty happy.

  Thanks to all with suggestions!

Not bad at all...

I really liked the Discovery rear sight and so replaced the larger rifle sight with the Discovery.  It has a narrower sight V and is smaller and IMO fits the gun better.
I used a #4 screw & nut to hold the shortened sight to the plastic breech.  I had to dremel the ridge in the center of the inside of the plastic breech to fit the nut in the breech.  This is done so that the bolt can move freely.  After the nut & sight were in place I ground down the nut to make more room for the bolt.  I drilled a small indentation in the top of the breech for the elevation screw to set in to further solidify the sight.
 





Oh ya,  The Discovery rear sight lines up with the standard 13xx front sight.  No modifications needed.

  nice Bill. You made up my mind, next order just that sight and not the other as well. Easier to mount too that way
