Yep - a the brownells kit contains the springs I used as well...
HB - I took Sako a dozen years to change the design on thier scope rings to a less soft head that wouldn't strip out.. And this only occured when multiple rep's chewed thier tail.
Engineers have HUGE ego's... I should know, I are one.
Either way, stronger spring, and making sure you claw is right and you are good to go.
THEY could and probably will reconfigure things in the Sako 25 ? (2025)
But like I said, if you are counting on an engineer to say "i was wrong" you are going to wait, a long,long time.
