Does anyone make an adjustable peep sight for the 1322?
The WGRS 54 fits a Crosman breech dovetail. There are different sized peeps that can be bought as well as notch sight blades that fit the base as well.

If you are using the stock breech just flip the rear sight over, it has a hole on the other side to make it a peep sight
If you have a steel breech you can use the Williams Peep Sight, you will need to add a bit of height to the front sight though.
I'm not sure if the Daisy 5899 will work for you, but they are only $16 plus another $7-8 S&H from Daisy. If you order multiple items from Daisy.
