I found this one in my old box of mags the other day that I never went through. Need to ask a little help if you guys don't mind. What type of spring is this and how reliable are these? It's basically a curled up flat piece of metal bent into a spring.

Most 30 rd magazines for the 10/22 use this style of spring.
They seem to hold up pretty well.

Snail spring...they last forever.
The also don't take up room in the bottom of the mag like a regular coil spring, so more rounds can fit in the mag.
I have a Eagle 18 round mag that uses the snail spring design for my P85 9mm that is the exact same length as the original Ruger 15 round mag.
18 in the mag + 1 in the chamber = 9 x 19.

I had one for a mini-14 it would not hold the bolt open. I got rid of it, i felt eagle was cheap and going to fail.

No bolt lock-back is a different issue than snail spring design.
The P85 mag is all metal and nicely made...different than the plastic rifle ones.
The Eagle rifle follower did not have a tall enough tab to engage the bolt lock on my Mini either.
But, it did feed and function great otherwise.

^ Go buy a Mini-30!
It's the simplest solution to the problem of what to do with those mags.
