The life of a bolt is anywhere from 12,000 to 20,000 rounds, a regular copper-colored spring lasts about 32,000 to 36,000 rounds. The copper colored spring can last up to three times longer than the bolt . . .

A USGI stainless steel action spring will last at least 36,000 rounds and cost about $4.00 to $5.00.

Your $20.00 Springco Spring will need to last 144,000 rounds in order to be a better value than a $5.00 spring, but you will have to shoot all 144,000 rounds, maybe more, to recoup the investment. That's poor economics.

Understood on the economics.

In terms of service life both springs are highly regarded.

The only negative that I'm aware of regarding Sprinco is something about action spring corrosion some years ago. Don't have any details though...
