So we decided to do a test on a bunch of magazine followers

[Nisser17]

Now if S&J would make a follower out of Stainless steel or any high grade alloy I would toss out my VangComp's and support the local boys.
But I have heard nothing but really good remarks about your followers and should be at the top of anyone's list of upgrades.

corect it got to about day 15 and there was not enough left parts left for me to reallt take a pic it was like soap day 20 al lthat was left of the norinco follower was about 30 little flecks of plastic.

I'm amazed it lasted that long. Mine dissolved in about 10 seconds flat when I tried a little brake clean on it to get the gross shipping grease off And yes I clean all my new guns metal parts in brake clean, works great

We have been asked manytimes to make some SS followers, but i dont think we will do it. Plus that really is Vangs think so i dont think i would want to do that.
It sort of go against our idea with the S&J follower.
The idea of the machined Delrin is that its teflon type plastic thats hard but self lubricating so less need for oild in the mag tube, less chance of oils stickign to dirt and jaming the mag tube, no rusting or breakdown liek steel and alum followers.
Bit not soft and cheap like many factory followers.

+1 for that. Mine works awesome, about 3-4 K rounds, and I never oil the mag tube.

I'd still like to see your test repeated with DEET.

MILSPEC parts need to be chemical resistant to resist chem agents, fuels, bug juice and cleaners. A cheap informal way to check for chemical resistance is DEET. If it can resist that it will work for anything.

It would help if you shoot at EOHC in the summer too!

ill see if i can find some old mil issue will give you cancer bug juice then ill test some out.

I think I have a case of bug juice still. I can tell you what will happen, they will melt, everything plastic will melt but there will be no bugs!

Not true. Try putting bug juice on C7 or C8 furniture. No melt. The Delrin should be impervious too. Chlorine and some acids break it down over time.

But the only real test is - a test.

I remember when we used to use the old bug juice, you'd get half way through writing out orders and your pen would start to disolve in your hand! Pain the rear end for that but it worked. If a follower survives that, it will live on after "the Big One" along with the cockroahes.
We used it to make night vision monocular bodies and never had an issue with it. Keeps it's size very well through various temperature ratings as well, important when needing a solid seal of components.
