Anyone have any experience with one of these. I was reading about this unit in a book I bought on airguns and it seems interesting.
I found quite a few references on the web regarding these, I'd be curious what they sell for in good condition. Seems like an accessory
I'd enjoy having for one of my K-31 rifles. Not sure how mainstream the caliber is. Didn't bump into one for sale.
Here is a decent reference to the device:
