Well this got my curiosity up and I tore into a old damaged sight to see how it is put in there.
It's just a captured ball.
The springs from the bottom provide the only tension.
BUT how they H%*!!? they get that very little dude in there and stay is beyond me.
IF they just send the ball I will bet you loose it just getting it out of the package. :shock: Maybe it's epoxy/cemented in... My thinking is they might load the hole w/ the cement and then touch the ball to it. Just a guess ,,, as there seems to be some cement type residue.
Flat; If your holding the gun down range, the little shinny ball bearing is at the 6 o'clock position. It very well might be missing, as the first sight body I grabbed to tear apart was missing the ball.
