I unloaded my USGI mags
They have been loaded with 28rds for over 5 yrs
They are just.fine
Also I have thermold 30 rounders that I loaded up on the same day
They are fine as well
Havent check / unloaded my D&H curve 20rd mags

Can't speak for other mags, but our polymer PMAGs do NOT have feedlip creep issues. Even without the Impact/Dust Cover, we've had mags fully loaded for five years now and have observed no issues.
FYI the max permissible width for USGI mags when measured at the rear of the feedlips is 0.4760".

I would think if my thermolds were okay the Pmag should do even better

Come on man its 5 years!!! I have shit in my fridge older than that. I dont mind Pmags but dang I get tired of reading this crap.

I suppose we should just get accustomed to it.
It is becoming the new normal.
Besides, I thought the subject of this thread was "Steel Mags Feed Lips?"
Is Magpul using steel feedlips now, and I just missed it?

The OP asked about steel vs. aluminum and "synthetics" which I guess would mean polymer magazines.
When I moved a few Summers ago I found shit in the back of my fridge that I didn't recognize, which meant it was left by the people that lived there before me (13 years).....
5 years for an M16 magazine is nothing. They can stay loaded for DECADES without a problem. I own mags that are half a century old that work perfectly

Sorry, I was responding to the assertation that polymer mags have feedlip problems. Besides, all my responses are of a factual and technical nature and I thought I was adding to the conversation. Did YOU know what the max permissible feedlip width is?
Also, I can only give data for the last five years as that's how long the PMAG has been in existence. I can't state facts regarding the future, or for other products, but I predict that a PMAG's feedlips will remain trouble free for many more years than that.

I don't generally think it has ever been identified as a real problem with any particular mags, but I would guess that if it were a problem steel would resist it the best.

Why would it matter? In the military the policy is to use mags until they don't work then toss them. A gauge was tried in VietNam to find out of spec mags and the problem was the specs didn't predict which mags worked and which ones didn't. On every deployment I've ever been on we were issued brand spankin new magazines at the start.......

Not necessarily. Depends on the thickness of the steel and its hardness rating. Stainless steel isn't exactly known for its toughness

Yes, Mr non-paying 2011 join date, you should. Site sponsors are paying thousands to keep the lights on here, and one of their privileges is the ability to defend and promote their products.

Does being condescending make you feel larger than life, or is it just your nature?
Everyone here was new at some time. Even you.
And I'd be willing to bet that most here were members for a while before they decided to pony up and become paying members.
That has been my plan all along. Hang out for a while and see how it goes. Then decide.
But sometimes I wonder if it's actually worth it.
Just for the record, I originally joined this site a long time ago.
Back in about '99 or '00 if I remember correctly.
But I was away for a while and couldn't get back in under my original user name.
So I recently re-registered. But I'm not exactly new around here, OK?
Thank you though, for your interest.

I was trying to assist you in not getting yourself thrown off of the site, which is what is eventually going to happen to you if you continue with your campaign to prove what a cool dude you are by making snarky comments about companies that pay a lot of money to support us.

That seems to be a popular tale told by snarky folk trying to establish their legitimacy.

Makes sense, but I was refering to mild steel and not stainless steel. One of the former sponsors here used to tout their SS mags as being the next greatest thing to Chobham armor, but in Dave Fortiers unscientific test it crumpled rather quickly.

Thanks for your assistance, but I am neither "snarky", nor trying to be a "cool dude".
I also will not kiss the behind of vendors nor "superior" members here.
Have me bounced if you will, but when I leave my lips will be clean and my breath fresh.
I think the Magpul reps are OK with me so far, as they have been playing along also.
But apparently their shorts aren't a tightly knit as yours.
And regarding my prior membership, that is the truth. Accusing me of being a liar doesn't change history.
And I don't need to "establish my legitimacy".....I am fully aware of who I am, and that's all that matters to me.
Now, friendly remarks made in jest go on here all the time, and no flags have been thrown so far.
I have been neither hateful nor defamatory.
Unlike yourself.

Please....what "course" are you referring to?
I'm not aware of any rules that I am in violation of, but I will go back and re-read them.
And if I am, I would hope that a mod. would let me know.
But regarding the quote you selected, I am right.

The gap between the lips is a horrible way to measure the lips, what prints are you looking at. If one lip is bent in and the other out, that us why the lips are measured from the side and there is a tolerance there as well as the welded body width and tolerance. The rear of the lips isn't the point where spreading occurs.
Those retarted feedlip gages make money only. Look at how wide the surefire lips are -.480.

According to the U.S. Army: PN13023560 MAGAZINE FEED LIPS WEAR TOOL
While I agree that feedlip width is not the only thing one should be looking at as there are numerous things that can affect feeding reliability, it is one spec to be aware of nonetheless. Also note, these dimensions are applicable to USGI alloy mags. Other brands of mags may or may not function fine outside this range.

Thank You. Also Thank You to all the others who kept it on target. I did not post the question to start a pissing contest, but was honestly looking for answers. I help some folks who asked me as they know I do test mags and I did not know the answer but kept seeing folks spread the information that left loaded mags have the lips spread. From the answers here the 'rumor' of spreading lips appears to be another 'urban myth', or a rumor spread way out of perportion.
With some of the answers in this thread we all can honestly evaluate our mags for optimum performance.
I am looking forward to buying my first Pmag to test, Now, should I buy new or used? What generation? With or without window?
What about 'other' synthetic mags?
For the record I will NOT be buying a Promag or a Tapco to test. I have already seen them at the range. They were BOTH being shot AT!
3/7/2012 4:52:54 PM
Troy mags and Lancer "L5" are high quality polymer mags, don't be afraid to buy a few of them either.
Israeli Orlite and Thermold polymer mags are good as well and can be found cheap. I consider them far better than the Tapco and Promag AR15 mags, but slightly "less" than the Troy or Lancer mags (PMags too, I suppose).

The entire premise of this thread is wrong. Niether Al or polymer mags have been shown to have problems with creep. If any material were to have problems with creep, it would not be steel.
Polymers exhibit creep more than Al or steel. The question is will it matter with a mag? The amount of creep can be kept negligible if designed properly. Glass can sag after billions of years (not hundreds as the erroneous stories of medieval glass panels suggests) but I would not worry about it with my windows. Nobody knows for sure if poly mags will hold up after being loaded up 10 years from now, but there's no indication that they won't so far.
Al is susceptible to creep and it has no endurance limit. This basically means you can apply a small cyclic load on an aluminum bar, it will yield and eventually break. It's a manageable problem though, because you just design it so that this will never happen in the lifetime of the product. And thus, airplanes don't fall out of the sky and mountain bikes don't spontaneously fall apart.
Steel however is more resistant to creep and has an endurance limit. That means if you keep the stress on the steel below its fatigue strength, say ~30K psi, it will never break no matter how many times you apply that load. Again, more important is the design. If a mag is stamped from steel that is too thin, it can exhibit creep or crack, but all things being equal, it is the least likely of the 3 materials to exhibit this failure.

Thank You.
Main thing I guess I needed to know is if any would FAIL like the PALM mag I tested and some Bulgarian 74 mags that bulged on me. While the PALM did not 'creep', unless you call a feed lip failure at the rear creep. That test and the resulting firestorm got nasty enough that I really do not want to repeat it.

Hardened steel at that, not stainless.
