Mort, the spring is 1/8" diameter and 5/16" long. I used a spring from from my local Ace Hardware spring drawer. A 700 spri g will also work with a little reliefe added by the trigger cross pin.
Hope this helps. -Al
With the steel one for a pattern, an aluminum version can be done on a water jet. I did a reverse of this to add weight to the bottom of my Hart/Sinclair rest.
Good shootin' :) -Al
Jeff, it was Field And Cave Outfitters that used to make those, along with other very well designed and made items. Unfortunately, they've ceased production of the shooting gear.
Try a 'Wanted' add on Accurate Shooter. One of the members there bought their remaining stock of items...
Gary was a smart, smart man and a heck of a gunsmith. He was also a true gentleman and a total class act.
The World is a better place for Gary having been here.
Wasn't a biggie to do using a 3/8" diameter, 82 degree carbide counter sink tool. Depth was .020...just enough to give a bit more angle on the neck approach.
Good shootin' -Al
