I don't know if anyone has tested like I am, but here it goes. I just recieved some PMAgs yesterday and decide to load 3 brand new ones with 30rds each, put the cap back on and leave them in my truck for the next couple of months. Since it was 93 at noon today, (120 in the cab after lunch), I thought it might be interesting to see how they hold up in the heat. 140 to 160 is not unusual inside temp by late afternoon. I am going to try to keep a log of the temps at least through August, then see how they work. Might be interesting and it might be a non-issue. Just me throwing my 2 cents in. By the way, after watching Slug-O's bus test, I must say I am impressed with the mags. If he can run them over, I should be able to bake them, no? Moses-ying |
Make sure you test them for proper operation before you put it through the torture test or you won't know if they were good in the first place. |
Leave the cap off on at least one of them. |

Record keeping offically started yesterday, and I changed the test a little. As per suggestions, all mags were function tested (and passed), numbered, and then loaded with 30rds each. Three have the caps on and three with the caps off. Some time after the summer monsoons are over (usually about the 1st of Sept) I will see how well they work. Moses-ying |

Well It has been 10 days of testing so far, not a lot of time so far. Since the 19th everyday so far has been at 110 or above. Inside the truck at about 5pm, it has been anywhere from 130 to 136, at about noon it is in the 115 to 122 range and at 8am it has been between 80 and 90. For what it is worth, I check the mags for signs of swelling or feed lip spreading and visually none has appeared. They still insert easily and drop free with no issues at all. Just as a side note, the week before I started record keeping, the A/C quit working. They had two whole weeks in there very warm all the time. The 22nd I finally got the a/c fixed so now we may ride around in comfort as we (Me and the mags) go to and from work. Moses-Ying |
We have just changed our PMag bodies and are replacing old bodies in the field. If you are doing testing let us send you the new versions as we can always use more test data. New Bodies are 07/07 marked. Let me know how many mags you have. |
Here's my question. I have a bunch of PMags and they all seem to be doing great. I have a variety of Black, OD and FDE mags, should all be replaced even if they are working fine now? |
We still have military units using the original 03/07 mags out there. That said please feel free to take advantage of our offer. You never know they might run better than those you have right now. |

What was changed on the new bodies and why? Also on a seperate question... does the PMag body use a standard spring but a longer internal body? Some testing by a friend showed it was having some issues locking the bolt back 100% of the time and I wondered if the longer mag body might have resulted in reduced spring pressure on the last round as the spring was extending longer and with less force than a USGI mag (which locked back 100% of the time) |
zzzzz.....Wake me up in ten years and maybe you will have a meaningful test.....zzzzzz |
The Pmag body is only longer by a small amount (enough to allow inserting with the bolt home on a full 30 rounds). Nothing has changed on the geometry just the way the body is gated (where the plastic is injected) and how it is cooled afterwards. the new system gives much greater consistancy and overall better mags. We thought it would be cool if everbody had access to these new bodies so we opened up a free replacement program. The extra cost is saved through not having to vet every mag replacement request that comes in. Here is the exchange info. Exchange info |

Thanks for doing that Magpul - I put in for the replacement bodies for mine already. Even though they have not malfunctioned yet a few do seem a little sluggish on the follower action. Thanks for being such a stand-up company, and I look forward to buying a whole butt-pile of new Pmags soon (when all the old revisions get off the shelves)! |
There shouldn't be that many in dealers hands as we have not shiped any for about 3 weeks. Brownells just got the first 07/07 shipment last week |
Are there any shipping charges I would have to pay if I exchanged my two PMAGs? |
They are shipping the bodies out with a paid return label, so it should be 100% free to you (minus gas to drop the package off) |
The website has a shipping charge but ignore that (we cannot shut it off). All the orders are processed manually and you will not be charged unless you keep the old mag bodies (which you can if you like the cost is $5 each) |
Cool. Thanks alot! |

Yes I am going to start over as soon as the new mag bodys show up. Just as a post script to the whole test thing. Back in 2000 I left 8 of the Orlite mags in my truck loaded for 6 months, starting on Feb. 1st and up through the middle of August just to see how they survived in the cold and heat. Temp ranged from 22 degrees up to 145. They were emptied at the S P Crater Shoot that August. All were loaded with 30rds and were used in a Colt LMG. The feed lips did spread a noticeable amount and still inserted ok but not as easily as G.I. mag. Long bursts of 10 to 12 rounds were done as well as mag dumps. The remote controlled airplanes that were targets were quite difficult targets to hit. Hopefully this will give you some enlightenment at to the reason for testing poly mags. |
Those are expensive targets!!!! |

The guys that put together the shoot at S P Crater had all kinds of interesting targets. The planes were shaped like Jap Zeros, there were wood stakes with dynamite on them and at night they put cylume stick on the front with dynamite on the back. Lots of stuff that goes boom. The night flights would have the cylume taped to the planes and some of the guys would try to follow the planes with spotlights. Not at all easy. The crew that brought the planes had 12 planes and spare parts to rebuild them many times. All but one were shot down and the one that didn't get shot down landed when it ran out of fuel. I counted 49 holes in it but it still flew. Got to hit a servo, motor,fuel tank or reciever to bring one down. Lots of fun and lots of ammo expended. The SP crater shoot is now done at Wikieup and is supposed to be bigger and better. |
