AX magazine issues

[Sixfivesavage]

I have two magazines, both AX mags. One came with the rifle, which I purchased new, the other was purchased new after I purchased the rifle. The one that came with the rifle has an issue with bolt over base malfunctions. No I don't have 11 rounds in it. It only happens with 9 or 10 loaded I believe. After the first two on a full mag, there doesn't seem to be any issues. The rounds are also held in the mag well enough that in order to make them slide forward or rearward you have to smack the mag pretty good into the heel of your hand or something to make em move. The mag that was bought after the rifle has noticeably less spring tension when loading ane no bolt over base issues but the rounds are so loosely held that they move forward and rearward very easily. Like even recoil is enough to make them move. I contacted AINA and have a rma number to send the one with the bolt over base issue back but before I do i figured I'd take them apart and see if they have any difference or maybe swap the spring and follower to the other mag and see if the issue persists. Oddly enough, this is what I found when I disassembled....

The weirdest part is the one with the shorter spring and less tension is the one with no bolt over base issues. So I ask those of you with AX rifles, what do your springs measure?

Anyone....?

I had the same issue with a couple of mags. Bolt would ride over the cartridge. AINA had me send them in and found the spring was out of spec on both. I never measured them...

All of mine look like the shorter or the two in your picture, even my magnum mags.

What's the sample size? I'm assuming a few. I'm thinking about just cutting the one I have instead of going through the trouble of sending it back. Do your rounds slide forward and back easy in the mags? I would have thought they would have more spring tension than the shorter one does. The long one of mine has a different shape to the spring too, not sure what the deal is.

Are both springs riveted to the ollower ?

I only looked at 2. I have about 20 spread across all AI lines. They all run no problem.

Yeah they slide pretty easily. Enough tension where they don’t slide under recoil though. You could snip it, or just let AI replace it. Probably just one spring that slipped through accidentally.

Yes

Mine slide over fairly easy. My guess since it’s factory (riveted) I’d guess either they left the spring long by accident or started making them longer for longevity purposes. But all the ones I have or seen are shorter.

I can understand a long or short spring slipping through occasionally. The part that is even weirder is the contour and strength of the other spring is completely different.
