Magpul fell into the same trap that a lot of industry folks do. There is absolutely no way to defend your product without looking like a whiny little girl. Everything they said was absolutely correct but they came off as whiny. There is little chance that this test would have been considered definitive by anyone without Magpul's comments. Their sales would not be impacted. The best option for a company in this situation is to just avoid comment entirely unless something absolutely untrue is being said about their product.


*I own a couple dozen Pmags but now I'm thinking I might also get a Troy and a Lancer just because they kind of look cool and they have performed pretty well.

No, this testing is great!  One should always try to satisfy their own curiosities.    My main point is that the results of these tests should be taken with a grain of salt due to the sample size being only one (1).

Regarding the comment, "... because your 'unscientific' way of dropping them is clearly not covered by any warranty", if you ever break a PMAG in the field for any reason we'll replace it.  Period.



Wait, even intentional destruction like this?

To be truly scientific, you would need a sample size of almost 400 for a 95% confidence level and 5% margin of error. When you guys get to doing these tests with all that R&D you talk about, please share.

As per your previous comment of there being cracks because there are so many PMAGs out there, this is flawed because I was referring to tests where only 1 mag of each type. In these tests (Fortier's, this one, various other tests on the net, etc...), the PMAG's feed lips consistently crack before mags like the Lancer fail.


As was noted earlier, we are in the midst of a comprehensive testing regimen right now and just very well may share some of the results.

Additionally, when trying to speak with authority, please get your facts straight- in both these tests as well as Fortier's the PMAG did NOT break a feed lip, only cracked the spine (which still allowed the mag to function properly BTW):

FYI: The truck video test was actually done impromptu to dispel any bias that the PMag was just like any other polymer magazine that preceded it.
We didn't know at the time it would become the standard mag benchmark test.
The PMag reputation was firmly formed in combat theaters over the last 3 years and not from a simple Youtube video.

Let me clarify my comment regarding this, as it was not directed at Magpul.
It was concerning ALL the videos regarding all the different mags that came out making it a mag benchmark test.
Keep in mind if you read the ENTIRE ARTICLE which includes a battery of tests NOT covered here that the PMAG did EXTREMELY well. THE ONLY ISSUE WAS AT THE 8.5 FOOT DROP TEST. This test exceeds the mil requirement. While the PMAG did split down the spine and spit some rounds out, it did function when I picked it up, placed it into a rifle and immediately fired the remaining rounds and the bolt locked back.
This is a very hard test which even the stainless steel CProducts mag failed. Please keep that in mind.

So, considering we ship millions of mags a year, you just don't see a lot of reporting of breakage.  Please, stop with the trolling and let's and get back to some more torture videos.

I'd like to point out that the only significant failure of the Lancer so far has been rust, which started when it was entirely degreased in the dishwasher. The rust seen on the Lancer feed lips and on some of the magazine springs would likely not be present if it weren't for high temperature detergent removing ALL the oils.



That is all.

Nowhere did I say "break". Your responses here are sad and unbecoming.

Cracked, broken, split , bruised, whatever.  Note that damaged feed lips are far more detrimental to the health of a magazine since they are directly responsible for properly feeding a cartridge.  A damaged spine has much less of an affect, especially once the mag is inserted in the mag well (as evidenced by both the tests you referenced).  The point that I was trying to make is that you are attempting to come off as an expert on these matters but just end up spouting off prejudiced opinions.  "Cracked" PMAGs ARE extremely rare, and if you're in disagreement with this I don't know what more I can say that hasn't already been said.

There are plenty of good options these days for polymer mags, the PMAG being an excellent example.  No where have we ever badmouthed any of our competitors and we're even known for publicly giving them credit where credit is due.  You, however, seem to have some sort of an agenda which is forcing me to respond to erroneous information presented here...

Again, please, let's not derail this thread any more than it already has.

OP, Permethrin is an excellent clothing-applied insecticide, but I'd like to request some tests using high concentration DEET.  DEET is a very effective solvent and eats away at a lot of plastics.  It is also commonly found in the field and therefore the probability of it coming in contact with a magazine is high (apply DEET with your hands and then touch your mags, etc.)

Well today was kinda cool, I was able to use an ultrasonic parts washer on the magazines.

So I decided why not? Lots of people clean guns and stuff in ultrasonic parts washers.

It was full of this solution.


Setting the mags in the basket.




Temp goes up to 250 degrees... so why not?  


Some soupy looking solution.


Mags down in there.


99 minutes is the max time.


Checking to make sure they haven't dissolved at the half way point.


Yup, that's the mags boiling in the washer solution.


They had some weird brown almost chalk on them, probably from the other crap washed before.


Very very hot.


Rinsing them off in another parts washer to get the chalk crud off.




Since they are spotless I figured I'd take some detailed pictures of their current damage.


Troy mag, nothing really changed with the body during the wash.


The Troy base plate is starting to fall apart.





TangoDown, nothing really changed.


But the mag is no longer glued together, it is now flexible at its seam.



Pmag, nothing changed.




Still cracked or broken or split (whatever we can call it without arguing) in the back of it.



Lancer, nothing changed in the mag body.


But the metal feed lips are almost spotless.




However the lips are also heavily pitted from the previous rust.





Tapco, nothing changed.


The back of the Tapco still has the crack.



Tan GI, has about 3% of its dry film lube left on it.


Either the heat or the wash took it all off.


The feed lips are damaged but still managed to feed during the last firing.




Base plate is pushed back and one of the keepers is deformed.


Tab barely catches the body.


And it looks like the front is beginning to split apart even though the welds all look intact.



Green GI, body seems the same but is also missing 97% of its dry film lube finish.


Must have been the heat or the wash that pulled it off.


Feed lips are crushed down, but still feeds OK.


This side feed lip is really pushed in.


Base plate is hanging on by its toe nail, going to need eye pro just to load this one.


So here is your last look at them before we start to get medieval on them.

Since we've acknowledged that most people would throw a cracked mag away, could you try drilling a strain relief hole in those two, to see if it stops further progression during the rest of the testing?  All you have to do is drill a small hole, 1/8" or smaller, at the very tip of the crack.

This is an awesome thread.  It appears to me that if all the manufacturers involved  make their magazines even half as well as those in this test, then we as consumers

can buy with confidence.  Thought I don't baby my magazines, I don't actually try to destroy them.  Keep up the good work.

All these mags are actually performing pretty well and I am impressed. Magpul, your mag has a crack and is still functioning! To me that makes it a cosmetic issue. The rust on the lancer is just as bad.

OP you have abused, heated and tried to dissolve all of these mags. The only thing left is to see if cold makes any of the plastics brittle enough to fail.

Any plans on doing the dry ice test? Thanks again for doing this!

I actually broke a mag, and I mean broke it for good...

Here they are all lined up.


Today's test will involve TWO ammo cans...


The first can is full of whats left of my IMI M855, for test fire purposes.


The second can has 16 pounds of chain in it to simulate the loaded weight of a 420 round can.


This 16 pound can also has the hillbilly drop mechanism on it.


So that it can be dropped onto the mags.  


All loaded up, which is becoming a pain with the Pmag, if you notice it's wearing the Lula...


Pmag, unable to hold its rounds.



So this drop test is pretty simple, lay mag on side, drop 16lb can on it, test fire.


Troy can drop.


TangoDown can drop.


Pmag can drop.


Pmag won't hold ammo.


Lancer can drop.


Tapco can drop, lost 5 rounds on drop, lost a bunch when I tried to insert it in the mag well.


Tan GI can drop, only holds 20 rounds.  Tan GI destroyed.


Green GI can drop.  Green GI fits better after being smashed...


The results of the side drop test.





So since its still kinda light I'll try one more drop test... drop it on their spines.



Troy spine with can.


Tango Down spine with can, TangoDown split in half.


Pmag spine with can. Follower jumped out a little, crack looks to have extended.


Lancer spine with can. Follower jumped up a little, feed lips opened a little.


Tapco spine with can.


Tan GI just to to bury the hatchet...


Green GI spine with can.  Mag is splitting and wont keep its floor plate on.


Dropping the 16lb can on their spines really did a number on them.


Troy, for the most part intact, will test fire again to check function.


TangoDown, glue dissolved, and broke in half, but can be pushed back together.


Pmag will not hold 30 rounds on its own anymore.


Because the crack.


Lancer has pitted feed lips.


And the follower jumped out, but was able to be pushed back in.


Tapco remains unchanged, except for the crack in the back.


Cracked Tapco.


Tan GI is done.






Green GI is almost toast, wont hold more then 20 rounds, and can't keep its floor plate on.


Also splitting at the seam.


Bulged in the front too.


My poor ammo can is all dented in the bottom now.






So now its time to spray them all with deet and see what happens...

I was going to try that, but to be fair not all mfg's make a translucent magazine.

It wouldn't be fair to put a clear/transparent up against a solid black since black is more durable.

I might do that, but if I do I would also have to reshape the keepers on the green GI mag.

And I don't know many people in the field that have a gerber powered drill press.

Is that Repel 100% DEET ?
If so then this should be good. I have been using the military 100% DEET and the newer 75% in the little green bottles and can say that stuff is hell on plastics and rubber. I've had rubber watch bands melt to black goo and synthetic stocks melt some where my cheek weld was.

If so then this should be good. I have been using the military 100% DEET and the newer 75% in the little green bottles and can say that stuff is hell on plastics and rubber. I've had rubber watch bands melt to black goo and synthetic stocks melt some where my cheek weld was.
Thanks again for this great thread.


I'm not expecting the DEET to do much. I thought the new lancers and pmags were designed with DEET in mind. As for the other mags who knows. But I think if you took deet to the first gen lancer it would eat it alive.

Doubt it, they're polymer, meaning it holds its self together with long molecular chains tangled up so you can't actually weld it back together.
I'm sure our friendly neighborhood Magpul rep will prove me I'm wrong.

Well if its anything like the lancer mag I completly melting, spraying it with certain chemicals will make the top layer goo, that will eventually dry hard again, so it might be possible. Not saying that it would hold together under any stress though

It would never be as strong.  They have ground fiber glass in there for strength - think little pieces of rebar.  The rebar is now snapped.  Glueing it back together, is cosmetic and likely would only last under the mildest conditions.  

Bear in mind, these things are cheap.  Just throw it away.  It would be good if WI57 would add a new one, since subsequent failures on a cracked magazine aren't really representative.  Successes too actually, since the crack now can act like a force absorbing spring, saving the other parts of the magazine.

But then, it's worth remembering he's mostly going this for his own entertainment.  The problem is, his entertainment is better than any professional test I've ever seen!   I love this guy!

I'm glad you added some sort of heavy side impact test. I was going to suggest something with a swinging weight and nothing behind the mags for them to be crushed against, but this was an interested test too.

As for dropping the weight on the spine, that had a predictable outcome. The force from that impact is trying to push the arch flat, just like a bridge, but unlike a nice bridge these have no end suports to keep that from happening.

If it is possibly, please try gluing the TangoDown mag back together and see if it still functions. Having a seam there gave it a nice failure point for the arc and may have actually worked in a sacrificial manner to save the rest of the magazine's structural integrity.

I agree, but heat and chemical welding are different on plastics. The most you'll get with a soldering iron is a mechanical bond and you'll likely add more stress to the crack.

On a tangent, the crack is like one in glass, on it's own, it'll keep pushing the halves apart. Granted the polymer has some give to it, but it's still under stress. Someone suggested drilling a small hole at the end of the crack. That would stop THAT crack, but wouldn't fix the problem. If you drilled the hole then cleared up the inside of the crack and superglue/duck tape/liquid nails, it'll hold up a bit longer.

Seeing as how Magpul recommended the test, this is a pretty safe bet.

Actually you are both right. You could melt the material so the force of the rounds would no longer spread the body apart under tension but this would be no where near as strong as an undamaged part with unbroken fibers.

In the real world a crack is a visual indicator of damage and to switch out the magazine for a new one.

Hey look, there's a big crack in my mag.

Should we throw it away and get a new one?

Nah, let's beat on it some more and keep using it.  (then bitch about the company that made it)

It is pretty easy to find opaque polymers that are DEET proof (as tested here). It is much harder with translucent materials. We tested one translucent material here that actually cracked in half within two minutes of just light exposure to DEET. So it can really affect the wrong material in a bad way quickly.

In most cases translucent polymers are considered DEET resistant (limited exposure) but not DEET proof (long term 100% exposure). This is how we classify the window in the Maglevel PMags.

The alluminum mags could be welded back and repaired with a little work.
