New Magpul PMAG 30 GEN M3

magpul-tm-tfb

Magpul has announced they will be shipping next generation PMAG, the PMAG GEN M3, this fall. It looks like the magazine will replace both the previous generation PMAG and the EMAG (Export MAG). Like the EMAG it will function reliably in non-Colt spec firearms such as the H&K 416/MR556A1, M27 IAR, SA-80 and FN SCAR 16.

Other new features include a redesigned bolt catch notch for increased bolt catch clearance, an over-travel stop on the spine to prevent over-insertion and a new slimmer and easily disassembled floorplate.

The magazine will be available in a windowed and a non-windowed version. The price has not been announced.

    Any word on when if the other colors will ship simultaneously?

    • http://www.thefirearmblog.com/blog/ Steve (The Firearm Blog)

      Sure, you can have any color as long as its black ;)

      Seriously though, I don’t know what other colors, if any, will be shipping.

    • FormerSFMedic

      Magpul is keeping these black. They have mentioned that the process of adding color would weaken the material used.

  • Nmate

    If I had to wager a guess, I’d say between six months and a year after the black ones ship. The black magazines are supposedly the strongest and they’re definitely the most popular.

  • Bob

    Here’s a question from way out in left field; will the spring tension be strong enough to load 30 rounds of 300blk in it and have it load properly?
    I haven’t had any problems with full power blackout loads, but with the 220gr subsonics I start to lose reliable feeding at around 22 rounds.

  • Fuddle

    Any word on a 20rd with the same enhancements?

  • hikerguy

    This should make both the Marine IAR riflemen and our overseas friends very happy.

    • DrewN

      I’m pretty sure what would really make IAR riflemen happy is a SAW.

    • W

      the marine automatic rifleman with a M27 wouldnt be authorized to use them anyways.

      hell, they arent even allowed to use HK’s own magazines designed for that weapon.

  • Pete Sheppard

    According to the ‘KitUp!’ blog, it will only be in black, since colors weaken the plastic: “The M3 should be available by November but in black only, Liptak said. “Anytime you add color to the polymer, it can decrease the strength.”

    I am hoping for a 20rd mag also. Hopefully, the slimmer floorplate will allow the folding of the SU16C stock.

    • RocketScientist

      Ditto on the SU-16C compatibility… that would make my day

    • Alex-mac

      If black is the strongest they should start painting them tan, save us the trouble.

    • W

      I want to see some facts to back up this “black magazine allegation” LOL.

      I smell a bull manure pile.

    • http://www.magpul.com Richard Fitzpatrick

      Basic molding 101

      Black uses carbon as the pigment which disrupts the base material less than the specific colored materials which are larger in molecule size.

      Natural is the strongest but is not UV resistant.

  • JC

    Hopefully this means we will see a lot of very cheap Gen 2 PMAGs in the near future…

    • http://www.magpul.com Richard Fitzpatrick

      The Gen 2 mags (M2), which have been faithfully serving in Iraq and Afghanistan for the last 5 years will continued to be made and sold but at a new discounted price.

  • gunslinger

    i’ll take some “surplus” Gen2 mags

  • Ian

    So glad there’s a shelf on the magazine so I can’t accidentally…overinsert it. Sure hope no one makes a firearm that has material in that area.

    And in regards to adding color to the plastic weakening it, black is a color.

    • Other Steve

      Correct, I don’t buy that black makes it weaker for once possible second.

      All nylons come “natural” colored which is a hideous combination pasty almond and “ick”. The black ones get just as much dye as the FDE ones.

      I would argue that the black are at a disadvantage because in the sun, they will absorb more UV than the other colors.

      None of that is measurable though.I’ve been working with injection molded plastics for 14 years now, I’ve never seen anyone try and sell that black was stronger.

      • Marc

        The dye absorbing UV light is a good thing, otherwise it would penetrate deeper and break more structural bonds.

    • jdun1911

      Over insertion is BS. It will make life a little more complicated when using it with standard GI molly mag pouch.

      Even Troy’s realized it was a bad idea. They got rid of insertion tab on their battlemag. Trying to fix a problem that doesn’t exist while at the same time creating a problem.

      I know there going to be a lot of people here that will disagree with me. Let me leave this little information. This is an immediate drill that is taught in the US military and firearms schools (minor change)for AR15 rifles. Notice the slap the magazine upward part.

      S.P.O.R.T

      a. Slap upward on the magazine to make sure it is properly seated.

      b. Pull the charging handle all the way back.

      c. Observe the ejection of the case or cartridge. Look into the chamber and check for obstructions.

      d. Release the charging handle to feed a new round in the chamber. Do not ride the charging handle.

      e. Tap the forward assist.

      f. Shoot. If the rifle still does not fire, inspect it to determine the cause of the stoppage or malfunction and take appropriate remedial action.

      • Trev

        SPORT is a bit dated. No need whatsoever for the forward assist tap.

        You can create problems shoving a round into the chamber that does not want to be there.

      • W

        over-insertion would never be a possibility when applying SPORTS anyways (btw, SPORTS is ridiculous; PORS is more on par) with the bolt in the way. There is no reason to slam or slap the bottom of the magazine to ensure seating of the mag or the cartridges because a bad magazine wouldnt seat correctly if you were loading the rifle to begin with.

        I guess you COULD over insert a Orlite magazine by slamming a magazine loaded into a rifle on a table or something. with a aluminum or modern polymer? very, very unlikely.

      • Geodkyt

        A. You CAN underinsert a magazine, and have it not firmly seated. Which can dink with feeding. Thus the SLAP. BTDT, seen hundreds of privates do it too.

        B. Forward assist is NOT the kiss of death a lot of square range shooters make it out to be. Sometimes (especially if you inadvertently rode the charging handle, or the bolt got slowed by crap you’re wearing or using for support brushing the bolt), the bolt doesn’t go home. Also, if your gun is filthy enough that the bolt is traveling through sludge. Thus the TAP.

        SPORTS was instituted based on lessons learned from actual combat experience in Vietnam, plus lessons remembered from the M14, M1 Garant, M1 Carbine, and M1918 BAR.

        Heck, Tap, Rack Bang is still a primary immediate action drill for pistols — pretty much SPORTS, with the differences being due to design and layout.

        I’ve seen versions of TRB that included using your thumb to ensure the slide was fully in battery after racking (Tap). No need to Observe the ejection, when it’s just as easy to wipe the chamber during the rack cycle — plus, unlike an M16, the ejection port should automatically be in your line of sight during TRB anyway!

        My issue with SPORTS as an NCO and Drill Sergeant was always that the most likely feed malfunction encountered with the M16 and real world GI issued magazines (ragged out, beaten, and battered. . . well beyond DX, but kept anyway) was a doublefeed, which SPORTS (or ANY immediate action drill) only makes worse.

      • W

        “A. You CAN underinsert a magazine, and have it not firmly seated. Which can dink with feeding. Thus the SLAP. BTDT, seen hundreds of privates do it too.”

        ive never heard of underinserting a M4 magazine. if it was underinserted, wouldnt it just fall out???

        like what i said before, if a magazine is good (which is easy to find out), it will catch and be seated where it is supposed to be.

        “Forward assist is NOT the kiss of death a lot of square range shooters make it out to be. Sometimes (especially if you inadvertently rode the charging handle, or the bolt got slowed by crap you’re wearing or using for support brushing the bolt), the bolt doesn’t go home. Also, if your gun is filthy enough that the bolt is traveling through sludge. Thus the TAP.”

        If you are familiar and well trained with your weapon, you can tell if the bolt is locked into battery or not, even with a fast tactical reload.

        To me, the “tap” portion of SPORTS is redundant. If the bolt wont lock all the way into battery after you release the charging handle, then you have other issues besides just the gun being dirty. The only weapons i have seen that didn’t lock all the way forward were usually guns with worn out buffer springs; a pretty common problem. Use the forward assist when you need it…and a well trained shooter can certainly tell if he/she needs it or not.

    • W

      Ive never had a issue nor have i heard of such a thing as AR15 magazine over-insertion.

      Take a look into a AR15 rifle’s upper receiver if you dont believe me.

      You shouldnt be slapping or hammering the bottom of the magazine anyways. a push is more than sufficient to make sure that it seats (and completely eliminates the possibility of over-insertion in my opinion). I have seen hammering the bottom of the magazine cause a multiple round round dump into a upper receiver.

      the polymer color “black” stronger? bullshit. enough said.

    • http://www.magpul.com Richard Fitzpatrick

      Over insertion is when the magazine is forced passed the magazine catch stop on an open bolt.

      The previous M2 PMag always had an over insertion stop built into the front forward lip of the magazine where it contacts with the M4′s magazine well.

      When this area had to be moved down to accommodate the HK 416/USMC IAR longer magazine well, the stop was moved to the rear to allow the magazine to be fielded in mixed M4/HK416 environments (like the USMC).

      As for color strength, please see my “basic molding 101″ post below.

        @”Richard Fitzpatrick”
        Still at it Leonard? Carbon in polymers turns it Grey, not black. Otherwise it turns brittle..

      • FormerSFMedic

        @Mike Knox- You do realize that Richard Fitzpatrick is the owner and founder of Magpul right? I don’t think there is much of an argument here.

        Well, this is the internet where anyone can pose as anybody..

  • Brandon

    That’s nice, but where’s the 40 rounder Magpul?

    • gunslinger

      i’m not a mag-ogolist, but why is there a 762×39 40rd mag, but not for 223?

      • Other Steve

        Because of the mag shape and case taper. x39 works better at 40 rounds because of the case and banana shape of the mag. There are downsides is that case taper for effects cambering, extraction/ejection, and brass life, etc etc etc.

      • gunslinger

        that make sense. seeing how “bent/curved” the AK mags look. just never gave it much thought…

      • Flounder

        Actually other steve the case taper improves reliablility of extraction chambering. No idea on the case life though. Of course most 7.62×39 is steel cased…

        The problem with a full case taper is that the mags have to have a curve on throughout the whole mag. Which is why the AK rifles have very short mag wells and the mags are completely banana shaped.

      • W

        I think the only 40 round mag that should exist would be a quad stacked variant of the 20 rounder. Or a quad stacked 60 rounder thats the same length as the 30s.

        its amazing how the Soviets conceived such magazines but in the US were trapped with 30 rounders. Im sure US Marine automatic riflemen with the M27 absolutely love that.

      • Ian

        AK Mags (and well…almost every other modern magazine design) were designed with this neat 1910s technology called full-curve. Americans still haven’t quite figured it out though.

        This is why other countries magazines are only limited by spring pressure as to how many rounds can be stuffed into a box magazine. The magazine curve is identical (or close enough) to the natural curve of the stacked cartridges so that internally, the rounds are just waiting their turn to arrive at the feed lips. In a straight magazine (for anything other than straight cartridges) the casings have to slide against each other to account for their case taper creating uneven feeding pressure.

        In a low capacity magazine, this isn’t normally a problem, e.g. the 20 round AR magazine. When you start adding capacity the follower becomes so tilted that it’s effectively useless. That is why 30 round AR magazines have a kink and curve at the bottom. This kink is where most of the problems in an AR magazine come from.

        Semi auto shooters won’t probably every notice the issue but in this transition area, the cartridges transfer from a neat, evenly spaced formation in the curve to a less natural one in the straight portion. If you watch the magazine with high speed video, you can see the rounds and follower stuttering which leads to the rounds at the feed lips having insufficient or uneven pressure which can cause misfeeds.

        The Pmag was the first AR magazine (to my knowledge) that attempted to fix this, though it does so incompletely. There is a “constant curve” inside the magazine so that pressure on each cartridge is uniform, but it isn’t quite the true curve of a .223. /magazine rant

      • Geodkyt

        Ian:

        Actually, Americans can figure this out. The problem is that the AR15 spec – FROM THE ARMY specified a 20 round mag. Given construction method, the 20 rounder was most easily, strongly, and cheaply built STRAIGHT.

        The mag well encloses quite a bit of this to provide the side-to side support and stability noticeably lacking in the AK or FAL. This increases reliability, especially given the mags were originally supposed to be disposable. The broaching of the magwell was most easily, strongly, and cheaply done STRAIGHT.

        So long as the 20-rounders were all they used, the mags had enough play for the slight internal curve the case design requires. No problem — gun worked as designed.

        The 30-round mag was only developed after the AR15 design was too set to alter the design to an AK style magwell. I believe there were over a million built and in military hands before the Army specified a need for a 30 round mag. At which point, Colt had to design a 30 round mag that, due to case shape, HAD to be slightly curved, but due to magwell design HAD to have a straight section up top.

      • W

        “were designed with this neat 1910s technology called full-curve. Americans still haven’t quite figured it out though.”

        full curve is only effective for the AK-style magazine locking style.

        I disagree strongly. the lack of full curve is not a problem of AR15 30 round magazines.

        The problem is a lack of a anti-tilting follower. It took the US a long time to figure this out (a embarrassingly long time). The Soviet AK magazines from the late 40s and 50s had anti-tilt followers. that is why they are so reliable.

        now that 30 round magazines with anti-tilt followers are becoming a norm and a standard rather than a luxury that they initially were, these magazines are very, very reliable. Reliable enough to remedy most of the reliability problems associated with the platform.

  • Lance

    I dont know. All US mags are good no problems with GI mags magpuls are good too. hope they all work.

    • John Doe

      G.I. mags are good without any problems? Can you repeat that?

      • Lance

        Used then over 10 year no real problems.

    • W

      GI magazines aren’t as bad as people think. for being a disposable item, they are surprisingly robust. The Brownells tan follower ones just plain work.

      The problem is that bad magazines arent thrown away or destroyed within a unit. theres thousands of the damned unworkable bastards floating around because of a variety of stupid reasons.

      • FormerSFMedic

        The whole GI mag issue is not that they won’t run the gun. For so many years I’ve heard shooters say that they won’t run or they’re unreliable and that’s not necessarily the case. Sure, the green followers were poorly designed and the floor plate is terrible, but in the right configuration the GI mag will run well. If you get a new mag with a tan follower and improved springs, then your good to go. With all that said, I have never had a GI mag that I would take to combat. That brings us to the actual problem……..durability. Every GI mag I have ever used has failed at some point.

  • dean

    Chunky floor plate….gay

  • jdun1911

    All these problem should have been fixed in their 2nd generation Pmag. Instead they gave the public Emag and the same major problems that was in the 1st.

    For those people that been here for sometime. You might remember me criticizing PMAG flaws. Remember how these fanboys defending Magpul tooth and nail?

    • Some guy

      Those were not major problems to begin with – it’s one thing to completely bomb a product release, it’s another to introduce enhanced versions of proven products and/or streamline logistics.

  • Mike Knox

    -And now Magpul and Porsche are neck and neck at coming up with new designs-..

  • John Doe

    Magpul (almost) always has very practical and thoughtful designs, but they’re just too damn expensive.

    • Sian

      $12 Pmags are too rich for your blood?

      • John Doe

        No, but $10 for Magpuls are. Duct tape does the same thing.

    • W

      here are your options:

      1.) find a cheaper hobby
      2.) get a different job that pays more or a second one
      3.) if you are really serious about being a gun owner, you CAN find extra money i.e. cut off the cable bill, tobacco, alcohol, sell television, video games, etc etc

      nothing gripes my ass more than people whining about the price of gun stuff, especially affordable, high quality items like magpul. you think its bad now, wait until there’s another assault weapons ban (if it happens). its funny how the cheapskate gun crowd changed their tune about mags after 94.

      I’ve heard of, “champagne tastes on a beer budget,” but it sounds like you have, “AR tastes on an AK budget.”

  • Cameron

    Take a note, Glock, in re: Gen 4. Minor tweaks to a proven design, nothing to screw with the reliability – except for the overtravel prevention bit in some limited circumstances.

    If you want to have a magazine for ARs where you can see the round count then leave the pigment out of the plastic you injecting into the mold. Simple.

      I don’t think you can get glass filled nylon in clear or translucent. The clear and translucent plastics are more brittle, and react with DEET bug repellent.
