I bought 2 Thermold mags the other day. When I got them home I loaded one up to try it out. It seemed like it needed some lubrication. I applied a little gun oil to the inside of the mags then put them back together. They functioned great.

Is gun oil ok to use on them or should I not have used anything at all??

Is there a better type of lub to use??

I'd appreciate some help with this.

What made you think it needed lubrication? I have more than 20(amature magaholic)Thermolds and they all worked perfect and never even thought of needing lube. What mold numbvers did you get? Are you sure they are Thermolds and not Orlites?

The mags might have some internal "flashing" from the molding process, a few dozen cycles should scrape this off. If now, you can open the bottom of the mags and do it yourself. I wouldn't recommend any lubricants, because you shouldn't really need them with these mags. I have about ten and they all work great. No problems even in rapid fire.

Well I never fired it before I lubricated it. It just seemed like it would help. All my AK47 synthetic waffle mags were lubricated when I got them so it seemed like a good idea at the time I guess..lol

Thermolds are supposed to be self Lubricating... I don't know if oiling them is a good thing.

Oh yeah the mold numbers are H21 and H22

Plastics don't do well with hydrocarbon (petroleum) based lubes. Use some petroleum free silicon lube if you have to have one.
I own both thermold and orelite mags and I agree with HighlandMac, they really don't require lubrication. Just clean them out once in a while.

All of mine are H21 and H22 as well. You really should clean them out and let the maggs do its thing. As stated before they may take a little "breaking in" but they work flawlessly in all my ARs.

OK thanks guys for helping me out. I'll take em apart and clean the oil out. The reason I was asking is that I ordered 8 more Thermolds from the equipment exchange and I wanted to make sure if I was doing the right thing or not.

Oil=dirt magnet, the only time (last week actually) my Thermolds failed was because I didn't get all the sand/gril out of them. Prior to last week I took them apart and just rinsed them through. The problem was the little bits of grit that stayed. I took an old 12 guage mop and wiped them all out. I'll let you know how they function tommorrow.

If you ol anything, it's the springs to keep them from corroding, otherwise any oil in any mag is a problem (failure to feed) just waiting to happen
