trigger
Jeffrey,
Back in the 1970's Frank Green used to manufacture them. He sold to Electronic Trigger Systems I believe, both addresses in Colorado. As far as I know they have been out of business for years.
The one for the Anschutz was nice in that it mounted on the rail and could be positioned anywhere.
I have one that is not working for whatever reason. I had used it for several years, sold it to a fellow shooter and later bought it back, not working.
