    Anyone ever tried Eezox on any of the non-stainless springs?

    I could send it back to Brownells, for what, $7 shipping? I could "make" JP take it back? I dunno, the juice isn't worth the squeeze, and I don't feel I was dealt poorly with, so meh. I dunno. Maybe I'll ask to trade it for some of their gas rings, which actually did perform great for me.
    You're right, I guess it is what it is but I just don't think it should rust inside the plastic bag. And I also agree on shipping back if you have to pay. IMO JP should take the springs back because they are rusting inside the sealed plastic bag - but if they don't, it wouldn't be worth my time or money.

    Thanks for the info. Much appreciated!!

    Oil it and shoot it. If it works, don't worry about a little rust.

    There have been some questions in the past about which springs are CS or standard spring steel or music wire, and which are 17-7. The way I tell the difference between stainless and non-stainless springs is with a spark test on a grinder.

    This involves lightly pressing the open end of the spring against a grinding wheel. Stainless springs will give no sparks or occasional sparks with heavier pressure, carbon steel springs (including CS) will give a bushy spark with plenty of branching.

    Here is some more info on spark testing in general

    https://en.m.wikipedia.org/wiki/Spark_testing

    If you have known CS and stainless springs, it's easy to see the difference for yourself.

    Of course this takes a few thou off the end of the spring, and cuts through the anti-corrosion layer of coated CS springs, but this shouldn't be too significant at the very end.

    I don't like corrosion on springs, because the surface of the spring is the most stressed part, and pitting here can lead to cracks.

    I use GI straight 20 rnd mags for my 5.45x39 AR which mainly shoots corrosive 7N6. I bought two batches from Brownells, first ones were with CS springs, the second batch was stainless steel springs. After two years of use, the CS springs were showing some surface rust. Zero rust on the stainless springs. That's about as close to an 'apples to apples' comparison I can think of.

    17-7 is a type of stainless steel. CS is chrome silicon.
