I just tried my gen 3 20's as I haven't had a chance to fire them yet, no problem, loaded 20 and locked in on closed bolt no problem.First thing I would do is disassemble and make sure there is nothing preventing the follower from going all the way down. With 20 there is plenty of room to still depress the rounds about another 1/8" I'd estimate.

I actually have the same issue with my Gen3 20 too, though not near as bad, it only makes a very little flat spot on the case in the same place. Mine also shifts the 2nd round sometimes when it doesn't want to seat, other times if I am gentle it will seat fine. I thought it was just the one I have so I ordered 2 more because I really like the size. They will actually be here tomorrow so I will check with those. I also thought it could be because of the use of the 30rd spring in the 20rd body.

I have 10 of these enroute and will check for this. I've heard they have same length spring as 30-rd pmags, but not sure if that's the culprit

Spring binding? Something not letting the follower seat as suggested?
Weird. I've ran 4 new 20s with great luck in 3 different rifles. All were perfect. They are my favorite mags. |
|
Just checked one of my new PMAG 20 rd Mags thru a Colt-LE, 2-Rock River's and a Nodak Spud and all functioned fine on all four rifles.
A little tight on all, when locking and seeding, but NO observable dents on brass when locking and racking! Magazine was loaded with a full 20 rounds of 55 gr Federal. Looks good on all my rifles during testing. /////////////////////////////////////////////////////////////// Update 4/25/2013 /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Tested again this morning with randomly selected 3 out of 8 Pmag 20 rounders rec'd by AZarmaments. All were dated stamped 3/2013 #5. Used again the above mentioned four rifles. Both Rock River Arms had RRA Carrier & Bolts. The Colt-LE and Nodak Spud both had standard Colt Carrier & Bolts. All magazines closed on both open and closed bolts without any problems. All four rifles functioned fawlessly with all three magazines in striping, feeding,chambering and ejection. All magazines were loaded with 20 rds of new Federal 55 gr ammo. Cycled at least five to seven rounds from each magazine throught each rifle. No problems. |

OP I just measured my 20 round Gen 3 Pmag at the same location as yours, from the top of the catch to the top of the lip and got the same 1.1140 reading.
I've ran through a CMMG Lower/BCM upper with no problems and a Rock River Lower/Stag Upper with no problems. Not sure what's going on there but just wanted to confirm my measurements were the same. |
|
You got 1.114? Can you double check? Mine was 1.140. Big big difference :)
The USGI 20 round may was 1.111 and fit like butter. Which is very close to your measurements. If you got 1.114 that would confirm that I got bad mags. |
|
Sorry, got an extra 1 in there. I got 1.140 just like you.
My Gen 1 Straight 20 has 1.120 My Gen M2 30 rounds has 1.130 No problems with any of them. |
|
Ok thanks. Yea all the other magazines fit ok, it's just the Gen M3 20 round. I've tried a ton of different guns at work, and I haven't found one gun yet that accepted them.

Something's not right here and I don't see how a hair over 1/20th of an inch is going to cause that big of a dent in the brass. Normally pmags have a little play in them and there should be enough play that 1/20th of an inch is not going to cause this. Keep in mind my gen 3 20-rd pmags haven't arrived yet and I'm only going by what's in this thread. However, something doesn't seem right and I don't think it's this.

I just got some Gen M3 20rd PMAGs in the mail today and tested them out. The mag will go in fine if the bolt is open but if the bolt is closed I have to forcefully slam the mag in. Seems like this is not an isolated issue, I would definitely like a response from Magpul.

IMO it appears the mag is too tall, and its struggling to push against the bolt carrier. Another weird thing I noticed was, when I take the mag out while trying to load it, the second round in the magazine is starting to face up ( if that makes sense). |

I think i'm going to disgree, and I'll explain to you why. When I tested the 4 mags (USGI 20 round, 2nd gen 20rd pmag, 3rd gen 30rd pmag, and 20 round 3rd gen pmag) As the number was higher on the measurement, the harder they were to get in. The USGI litteraly slide into the lower and locked in with zero effort, the 30 round 3rd Gen was the next easiest, the 20 round 2nd Gen was GOOD, but not as easy as the previous two, and ultimately the 20 round 3rd Gen just didn't want to work. How easy the mag went in was consistent with with the measurements from 1.111 being the easiest to 1.14 being nearly impossible (with the bolt closed). I wouldn't care, but god forbid if I ever am in a bad fire fight and I have to reload when there are still a couple rounds left in the current mag, I don't want to have to struggle with the bolt closed. |

I measured mine and the 20 M3 us definitely the biggest between the top of the feed lips and the indent. I also tried my 30rd M3 again and it doesn't lock in as nice as the older PMAGs either, but the second round hasn't shifted in that one yet like in the 20 rounders. |

Did anyone else get these 20rd PMAGs with issues from AZarmament? Not blaming them in anyway, they had great prices and fast shipping, just want to know if it was one batch that had this issue.

All of mine came from DSGARMS. I ordered late December, got them about a week and a half ago.
I wish magpul would chime in on this. |

Talked to engineering yesterday afternoon and did some initial testing last night. Pulled out a bunch of samples of mags from different tools and time frames, loaded them up, grabbed a handful of rifles spanning 3 different lower receivers and 3 brands of bolt carrier group, and had at it with a micrometer and some tac reloads. UPDATE--Testing guys ran through an additional 17 rifle platforms with same results. We do not have a Troy platform to test which was one of the problem platforms in this thread.
The dimension you are measuring, as it's on an angle and for various other reasons, should not be critical to the function we are talking about. Even if it were, the magazine would prevent the insertion and the top round would not be damaged--that being said, just to make sure we're talking apples to apples, I measured all the GEN M3 20 rounders, and got the same value as you, 1.139-1.140", so we are the same by that metric. The mags used in pre-release testing measure the same as well. All magazines inserted easily on a closed bolt, loaded to 20 rounds, and even with some abusive insertion, no damage could be induced on the top round. The overtravel stop should prevent that possibility. In the pre-release phase, we did compatibility testing for closed bolt insertion and function on about 2 dozen different combinations of compatible firearms, also without issue, so this is an interesting problem. I could prevent closed bolt insertion by loading the 21st round (absolutely not a recommended practice), and could cause damage to the top round by trying to slap a magazine of 21 home on a closed bolt. I'm not saying that's what's going on here, and don't mean to insult anyone's counting skills, but if we hadn't seen it before, I wouldn't mention it. We specifically design the PMAGs to have no issue going home on closed bolt at stated capacity by allowing that extra bit of follower travel, but the downside is that you can force the extra round in there and cause problems. If there are indeed 20 rounds in the mag, with the top round on the right, then disregard this. I also saw that the issue in at least one instance occurred with 10 rounds in the mag, so in that case, at least, something else is at play. I would take a look at contact between the over-insertion stop and the rear of the magazine well. Rock the magazine forward and back under ther pressure of attempted insertion and see if it locks. Some aftermarket mag well and triggerguard combinations can create issues. All that said, we'd like to get you sorted out one way or the other. Please PM me a phone number where you can be reached, and I'll have Justin give you a call to get your magazines swapped out. We'd like to examine the magazines to see what is going on. We'd also like to know the brand of rifle/lower receiver/BCG combinations that are giving you issues so we can attempt to duplicate. Once we know what the combination of parts is, we'll try to duplicate with the magazines we have here, and then when we get your return we'll do a detailed exam and figure out what's up. It's not beyond the realm of possibility that there is some funky dimensional issue somewhere that is outside our normal checks, and somehow snuck through on a handful of mags. If there is, we'll adjust QC to make sure we catch the anomaly in the future. I can say that we've received solid positive feedback from extensive field testing on this product, so it should be an isolated issue. |

After a little more tinkering around I think I figured out what the problem with some of these PMAG 20s is, I believe it has something to do with the spring tension. After talking to a friend he suggested taking the mag apart and just trying to insert the body in without the spring. Turns out without the spring the magazine goes in and comes out easily with the bolt open or closed. Magpul, I hope this helps you guys and I look forward to hearing from you about getting some replacement mags, I have already PM's my info to you guys.

I received two of these a couple days ago from Primary Arms, date code 3/13, and they also measure at 1.14".
I loaded them with 20 rounds and they fit just fine against a closed bolt in six different AR's, all RRA, Spikes or CMMG, with no problems at all. |

I have the same issues with my 20rd M3 mags. I purchased mine through Azarmament so they are probably the same lot #. I tested 2 out of 5 and they both had the same issues. If i tried to load a mag swiftly(std procedure) it would not lock in and the 2nd round in the mag became jammed on the 1st, however if I was to gently insert the mag with some work it would lock. I verified that the overtravel stop on the mag body was not interfering with the magwell. I tested these in 2 different guns while also checking a USGI 20 rd mag and a 30 rd MOE Pmag, both of which worked perfectly. I did not get an indentation on my casing like the original poster, but it did seem to scar/flat spot the top round. Additionally I checked the mag downloaded to 19 and 18 rounds and it still would not insert and lock properly, indicating to me that the follower was not bottoming out or binding. Tension to insert on a closed bolt was definitely increased, I was also curious if removing or lowering the over travel would allow me to seat the mag's easier but I did not modify this, just something to think about.

If you've sent contact info, you should be contacted by CS shortly. OP, your mags are on the way. We will be very interested in taking a look at these returned mags when they come in. We're at 2 dozen different magazine lots and over 20 different rifles and are still unable to duplicate anything resembling this, so now we're curious as to what it could be. We are extremely confident that this is an extremely small number of magazines that might be affected by any problem with the testing that we've done.
The only possible thing we can come up with is perhaps a follower or lockplate leg is long, but it would be almost impossible for that to happen to a degree that would cause any problem, because of the way they are made, and the generous clearances to specifically allow for easy closed-bolt reloads. One thing that you need to keep in mind is that our new 20 uses the 30rd spring...so spring tension is exactly the same on a fully loaded 20 as a fully loaded 30...the feed pressure is thus the same as the top 20 rounds in a 30, rather than the bottom 20, as with a shorter spring. This increases reliability, especially in a gun that is suppressed or overgassed. What is different is that you only have the leverage of the 20 round body, and perhaps the expectation of weaker spring force when compared to other 20 rd mags. We have a sample of about 400 closed bolt insertion tests that measures force to insert magazine to lockup with the above combinations of mags and rifles, and they fall into the exact same narrow range of force in pounds required as the 30 rounders. They can, however, "feel" slightly more difficult to seat sometimes due to the shorter body. I'm not saying that we're discounting these claims as the above...we'll take a hard look at the mags when they come in. |

Thanks CS contacted me this morning. I have a Troy Defense Carbine. As I stated before I think it may be an issue with the spring or follower since the body of the magazine will go in and out easily with them removed whether the bolt is open or closed. |

I received five 20 round M3's last week from Primary Arms and thay measure 1.140
I loaded 20 rounds of XM193 into one of them and it incerted into 9 different AR's on a closed bolt with no problem Two Spikes, YHM, DSA, Two Superior Arms, Two Del-Tons and a Stag Arms Bolts were LMT, RRA, Spikes, BMC and American Spirit |

I haven't tried them in any other guns yet. Do you all still have ANY Gen 2 20 round mags at your facility? Those work GREAT with my rifle. |

I may have found the issue, at least in my case. I just got back home from traveling. Doorstep had boxes of various pmags. I loaded the m3 20-rd mags and tested. Mag inserted fine with no ammo. However. After fully loaded, it was very difficult to seat and had to slam bottom hard to seat! Next I tried to cycle through the 20 rounds and every single round hung up bolt and had to use assist to get each round to feed! It seems when loading that you need to ensure to not let rounds jam next to each other. Not sure why this doesn't appear to be an issue with any other pmag but it certainly is with these. I reloaded it again but this time I pressed and slid back a new round in half way then pushed prior round next to it down to unjam the two from each other. After loading 20 in mag, I cycled through all rounds and not a single jam. Third time loading, I let the new round load naturally again and same problem occurred. You must unbind the two round rounds each time a new one is loaded. I can duplicate it but need to spend time with family right now. More later...

Okay, did some more testing and I can replicate the bolt jamming as well as the condition where you can NOT insert the mag!!! This is a huge design flaw and puts users in harms way. All you have to do to easily replicate the insertion issue is to lightly take your fingernail and lift up on the front of the second round? This causes the front of the first and second rounds to jam together as the are side by side! There is too much lateral play, that allows this condition to occur. You can also cause this issue, depending on how you load rounds into your mags. If you are used to load the rounds toward front of mag and sliding back, this causes the jamming too. If you place new rounds directly above and push them straight down, it does not occur. Trust, this problem does not happen on gen1 20-round mags.
Magpul, the gen3 20-round mags are not reliable and need to all be pulled back. I am to believe they are all flawed as this is a design issue. |

Also, why would you ever want to lift up the second round? This strikes me as a condition that would never occur. No offense man, but I think you're doing something wrong. Some pictures would be helpful for further clarification. Also what ammo are you using? If the ammo being used was too narrow I might be able to see this as a problem. I have both Gen1 20 round and Gen3 20 round PMAGS and haven't had a lick of trouble with either using XM193. |

I have both Gen1 20 round and Gen3 20 round PMAGS and haven't had a lick of trouble with either using XM193. I know how to load the mags, was trying to help find cause of problem by replicating. It barely takes any effort at all to lift up on second round as there is nothing preventing it from lifting up. I realize I am not supposed to do this, but I am trying to show you how to simulate what is occuring. A light shake or slight movement can cause the rounds to jam against each other. Instead of denying that this is an issue., lets all load one up and see for yourself. It's a huge flaw and exists on all size M3 PMAGS, but it's more prevalent on the 20-rounders. To see the problem yourself, fully load both a Gen1 & Gen3 20-rd pmag and look at the front of the followers. Notice how the gen3 has the little nipple missing in front of mag that is supposed to appear right where the little notch in the follower is? Also there is more play on the outside of the loaded rounds where those outer two nipples are? Move the rounds a little, even try lifting on 2nd round just to replicate issue I mentioned earlier and you will see how easy problem can show itself. It jams the rounds together and could happen anywhere the rounds touch each other in the mag! When this occurs, you can not insert mag or can cause FTF if mag did get loaded. It seems that the increased spring pressure in the 20-round mag forces the rounds into this condition easier than the 10 and 30 round M3 PMAGs, at least that's what I am seeing here. |

Ok, so I took a fully loaded M3 20 rounder. I got a small screwdriver and tried to pull up on the bullet of the second round up, would come up a little but when I released it, it would just get squeezed back down to its normal position.
Can't say I had any success duplicating it. Again, pics would be helpful. |
|
Better yet, there's a video. This time using new American Eagle Varmint ammo
Now you'll notice the second round can stay up, lodged against the side of the first round. Now imagine what happens when I stick the mag into the magwell? Just in case you cant imagine it, the carrier puts pressure down on the first round and lodges even hard againt the SIDE of the second round. The mag will not lock in. I too was skeptic that the OP was doig something wrong and you can see that on the first page. However, this issue is actually very serious and I have confirmed his concern. This jamming problem can occur anywhere in the mag |
|
Now this second video actually shows what happens as a result of two rounds being jammed againts each other. Keep in mind it didn't take any force to cause this condition - it occured by the round underneath it just barely moving. Look what happens when I push down on the first round.
|

After seeing this thread, I checked a couple of my mags. The magazine from 1/2013 was fine with 20 rounds seating on a closed bolt. Doing the same with the magazine from 3/2013 the second from top round came loose with the rear pushing down and front pushing up, similar to the first video. The second from the top round can be physically manipulated to come up nearly side by side with the top round. This can also be done with a M2 30 round magazine from 7/2009. It does not seem to cause an issue for me as both the top and second from top round chambered without issue from this position. I am unable to push down the top round like in the second video.

I am having the same issues with my mags. Trying to insert my mag actually causes the 2nd round to jam upward against the 1st round. Once it is jammed it will not feed or insert properly. I tested this many times with the same results.
Pictures of 2nd round jammed after failed insertion attempt. http://i1337.photobucket.com/albums/o661/hwmeador/2013-04-18_19-25-42_735_zps395413c4.jpg http://i1337.photobucket.com/albums/o661/hwmeador/2013-04-18_19-25-36_400_zpsb2a3e0b3.jpg |

Yes, you can pry the second round up. You can do the same thing with any mag. We've tested this condition extensively. In a PMAG, as soon as the bolt face hits the top round, it generally self corrects enough to feed, and feeds fine in 100% of the instances we've tried. We've even pounded the feed lips of a fully loaded mag as hard as we could to induce the worst possible stack anomaly on USGI and M3s, and MOEs, and other mfg. magazines, and tested same from feed lip drops and prying up the round manually.
In 100% of the instances, we could insert the PMAGs on a closed bolt, and the magazine fed completely normally. One DPMS gun and one Nordic receiver build were the only two that didn't 'snick" neatly into place, and they still seated with less pressure than a USGI mag normally loaded to 29 rounds. More pressure was required to seat some magazines in some guns if the top round juxtaposition was intentionally induced over the force required in a normally situated stack, but all seated without exceeding 25 lbs or so. Admittedly, we only tested, Knights, DPMS, Colt, Sig, Ruger, LWRC, Bushmaster, HK, Armalite, Aero, Smith and Wesson, Larue, Rock River, the Nordic build, a DelTon, and a Tavor, so we didn't hit every possible firearm. There were two competing magazines which could not be seated on a closed bolt with the pried up condition, the USGI, and one other leading polymer brand. These also would not feed from this condition. All GEN M2/MOE and GEN M3 PMAGs fed normally. With over a half million rounds in initial development and continuing QC testing plus several thousand magazines in operational field testing, we are confident this is not an issue. If you've got mags that you are unhappy with, however, we'd be glad to examine them and swap out any deficiencies through normal customer service channels. We also take all returns seriously, and we investigate all issues, and we'll continue to test all returned mags, and each production lot rigorously wrt this and all other potential issues. |

Okay, I will return them to the place I purchased them from. I've already been in contact with the place of purchase and made them aware of the issue. I purchased ten M3 20-rounders but have only opened one package. I will open the other nine and test them when I return back home.
Make no mistake or assumption, there is an issue with these mags. I will gladly get them back to you through my reseller for further testing. I can assure you that the mag I tested can NOT be inserted into the magwell fully on a closed bolt when the problem occurs... |

Magpul, these are the new magazines I've received. Here is what is happening. I have duplicated this problem on a rock river, bushmaster, and my accurate tool AR15.
