The next-generation PMAG 30 GEN M3 Window is a 30-round 5.56×45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons that features transparent windows to allow rapid visual identification of approximate number of rounds remaining. Along with expanded feature set and compatibility, the GEN M3 Window incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed rigorous military performance specifications.While the GEN M3 is optimized for Colt-spec AR15/M4 platforms, modified internal and external geometry also permits operation with a range of additional weapons such as the HK® 416/MR556A1/M27 IAR, British SA-80, FN® SCAR™ MK 16/16S, and others.Similar to the MOE PMAG, the GEN M3 Window features a long-life USGI-spec stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding, and simple tool-less disassembly to ease cleaning.In addition, a redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons. Low profile ribs and new aggressive front and rear texture gives positive control of the GEN M3 in all environments, and a paint pen dot matrix has been added to the bottom panel of the body to allow easy marking by the end user for identification. The new, easy to disassemble flared floorplate aids extraction and handling of the magazine while providing improved drop protection, but is slightly slimmer than before for better compatibility with tight double and triple magazine pouches. An included pop-off Impact/Dust Cover can optionally be used to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit.Durable dual-side transparent windows allow for quick determination of approximate number of rounds remaining in the magazine. Utilizing a high visibility indicator coil on the spring and numerical markers on the magazine body, the MagLevel™ system provides positive verification without affecting the durability or reliability of the magazine.Made in U.S.A.

  9. lauderale (verified owner)

    Awesome product, the packaging was great.

  10. Phill (verified owner)

    Best mags on the market, at a great price with fast shipping. Gotta love BigTex.

  11. Greg S (verified owner)

    Best price that can be currently found for 30rd Windowed PMags. Ordered 2, received tracking info within probably 12 hours, took only a few days from TX to PA. Great mags, great price, great shipping. Another great purchase experience from Big Tex Outdoors!

  12. Keith Parker (verified owner)

    I’ve tried quite a few other AR mags over the years from USGI to MSAR to MFT and PMAGs just work perfectly every time. And that’s really what you want out of a mag, it just works, every time. They feel great in the hand, good grip that builds confidence. I think the Gen 3 are worth a small premium, I use the grid markings to show what ammo I have stored in them, eg 85 for M855, 19 for M193, 23 for American Eagle 223, etc. Again, I think the window is worth the small premium, I keep them full or empty so even with the dust cover on I can know at a glance if I’ve got 30 ready to go and what type. Huge shout out to Big Tex, great prices, perfect communication and speedy shipping. What more could you ask for!? I’ll be buying more from them soon!

  13. falcons.edwards (verified owner)

    I much prefer these compared to the metal lancers mags. Gen 3 is a worthy upgrade for not much more.
    Plus I look cooler with a windowed mag.

  14. Brent Bingman (verified owner)

    Lighting fast shipping! The mag with the window is great.

  15. Bernard Goal (verified owner)

    Can’t go wrong with PMAGs. Fast shipping from Big Tex as well

  16. Hunter Crumley (verified owner)

    What is there to say? They’re solid, and they just work. Good price on the gen3s from BTO as usual.

  17. Brian Sapp (verified owner)

    Great price and shipped fast. Was offered way more than this price for all of mine, don’t have them anymore.

  18. cameronsdean (verified owner)

    Great mags from a great outfit

  19. benvr8 (verified owner)

    Great offering from BTO and a great value. Really hard to beat windowed Magpul PMAGS for value and robustness/durability. Thanks again!

  20. Greg S (verified owner)

    Price that can’t be beat, lightning fast shipping; another great transaction from Big Tex Outdoors!

  21. Emmanuelle Albino (verified owner)

    Great item and price. Shipped super fast. Excellent company.

  22. Aaron S (verified owner)

    Mags are fantastic. Easy cleaning, take a beating and fit great. With the fast shipping, it’s a no brainer.

  23. D_H (verified owner)

    Big Tex is really on their game. Good prices and fast shipping. PMags are proven and the window is nice for spot checks on how many rounds you have left

  24. Jeff Barnes (verified owner)

    Big Tex is awesome! I only had the Gen 2 mag for my AR and thise Gen 3 with the window not only has the same quality functionality but improved with the window and orange capacity marker.

  25. makesh_wars (verified owner)

    Still (probably) the best magazines for your AR. Either with, or without the window.

  26. Brendon Bennett (verified owner)

    P mags over all other mags

  27. ROBERT ROSENBUSH (verified owner)

    Awesome price, fast shipping. Can never go wrong with Big Tex!!!
