Everyone loses a ball now and then

This is a direct replacement for many adjustable sights on 1911's and 22 target pistols. If you have already spent 4 hours looking for the one that fell off your workbench - then you know having a bag of 20 is not too many.

Detent ball kit

Good assortment

These Balls Rock!!!

I plan on using one of them to secure a bubble level ala the style of the FlatlineOps anti-cant device. They're round, they're hard, and they're 3/32" diameter. They are what I asked for and need.

must have

This kit will keep you going. Its very easy to loose a detent ball while working on guns. I know I have. You can go to this kit and locate the right size ball to put into the gun.
