Are you guys really cleaning them that often that this is an issue? I really think you're splitting hairs over this.

    Wash, rinse, repeat as necessary...

    Agree.

    The spring thing is a constant discussion point with a lot of mis-information. Having spent a lot of time talking with the good folks at ISMI, they advise that SS springs only have about 10% of their life available when NEW! This is really the main reason why most EVERY GUN manufacturer recommends that you change out the springs in your gun (buffer spring, mag spring, recoil spring, extractor spring, etc) every 3-5 thousand rounds.

    CS springs typically have over 100,000 revoulutions before a loss in power is recognized. With that said, not ALL CS is created equal. There are different grades of it and the cheaper CS (like the kind that CProducts uses) will RUST!

    I personally use ISMI or Tactical Spring Companies CS buffer, recoil and mag springs in all my weapons. No rust and no changing springs after the 5K mark.

    I picked up a non-assembled ARC mag...

    And a CS spring, same as the one used in the ARC, but without the moly coating...

    Then I boiled some salt water underneath the spring...



    It was boiled for about 4 hours and then left above the salt water for another 12...The results were not pretty! Note that the ends which were not directly above the water are not oxidized at all. I have not cleaned this spring in any manner.



    I then assembled the magazine...after filing down the "snappy thingies" so that I could hopefully get the dang thing apart to inspect after a while...



    The spring does not seem to have lost any of its...springiness.

    I will do my best to rig up a machine with which to cycle the follower several thousand/million times.

    i just tried 2 different ARC's in a mid-length sabre,,,both just simply refused to feed. tried a 20 rnd. p-mag,, 20 rnd. ss c-products, 20 rnd. NHMTG, and 30 rnd lancer at the same time with no FTF's. my buddy put the ARC in his 6920,,,,no problems. the cartridge would get about half-way out of the mag,, then the bolt would ride on top of it. for some reason the bolt was out-running the mag in the sabre with the ARC mags. the sabre has a ar-15 BCG, and a standard buffer, of course the 6920 had neither. reckon if i put a spare LMT m-16 BCG, and an h-buffer in there it would act right???? i know simple the solution,,run lancers and p-mags,i gave my buddy one of the ARC's, still have 3 left,,so just wondering. gonna try them in a smith 15a in the next few days

    This is also a spring from a TD ARC mag. If it looks deformed, that's because I crushed the ARC mag on a press.

    Unlike the spring above, this one is moly coated.

    It was subjected to the same test - actually, a much longer version, I added water to the pot several times, it took over 10 hours.

    Little if any rust is visible. Lots of salt caked on to the spring, though.

    So, what have I learned? Well, a CS spring will rust, but the spring will still function. A moly coated CS spring effectively will not rust, and it will still function as intended.

    I am not sure if you have been reading the same thread I have, but the springs used by TD are high quality.

    Also, the ARC mag is a quality mag and works 100% in all my weapons.

    Bullseye, what kind of problems are you having and what kind of gun is the mag being run in?

    Grant,
    Speaking of Tactical Spring Companies, I have been wondering how many guys here are using their unusually large extractor spring in their AR's???
    I bought a Tactical Springs buffer/recoil spring from you (G&R) a while back, and I was pleased to find it had that huge extractor spring included with it.
    As you already know, that extractor spring was HUGE, and MUCH larger/longer/thicker diameter coiled, then ANY other extractor spring on the market.
    In fact, it's almost TOO big, and is SO DIFFICULT to install, even with pliers. It can be installed however.
    It is also the ONLY TRUE 5 coil spring I have EVER seen, and I've bought and used them all. It actually has FIVE coils, unlike all the others I've purchased in the past.
    I was just wondering if you Grant, or anyone else here had used those huge extractor springs, or if anyone knows why they are SO much bigger than all other extractor springs on the market? ALL the G&R tactical, BCM/etc extractor springs I've ever tried, have NOT been 5 coil springs, but rather 4, or maybe 4.5 coils...
    (despite being advertised as "5 coil" springs)...???
    "ROLL RIGHT SNIPER!"
