Pics of a superb bench-made sliding M70 tang safety are on the doublegunshop.com's single-barrel forum.

This conversion also has a replacement trigger piece with FULLY-ADJUSTABLE sear engagement and could easily be fitted with a single-set mechanism.

A nice version of a 'stalking' safety, placed in exactly the right position for instant use by either right- or left-handers.

Thanks for posting this. I own the rifle and would much appreciate any leads as to who made the trigger. It took a lot of gunsmithing to build this and I doubt it's one of a kind.

Pictures of the stock were just posted on the "Custom Rifles" forum here by Michael Petrov. If anyone recognizes who made the stock I'd like to know that too.
