Some things can be improved and some things can’t. Since Magpul decided their popular D-60 AR/M4 drum magazine is pretty much as good as it gets, the only thing left was to make a bigger louder version. Presenting the PMAG D-50 LR/SR GEN M3 magazine for 7/62/.308.



Here’s their press release . . .

A few years ago, we introduced the PMAG D-60® AR/M4, and ever since then, we’ve been working on how to make it better… and we couldn’t. Instead, we decided to make it bigger and louder. Introducing the Magpul PMAG® D-50™ LR/SR GEN M3™. Designed for those looking to carry 50 rounds of 7.62×51 NATO, because bigger is always better, no matter what anyone tells you.

The D-50 is a rugged, lightweight, and reliable 50-round polymer drum magazine designed for 7.62×51 NATO/.308 Winchester ammunition for SR25/M110 pattern rifles. It’s capable of using longer-than-SAAMI-spec match ammunition, up to 2.830” OAL, such as M118LR.

Engineered to the same exacting standards as the famous Magpul PMAG and PMAG D-60 drum magazines, the D-50 continues the PMAG tradition of high-capacity performance and dependability.  In addition, the D-50 brings GEN M3 features, which means enhanced strength, durability, and reliability. A ratcheting loading lever removes spring tension, making the D-50 easily loadable by hand.

An anti-glare translucent window on the rear of the drum makes for quick positive visual indication of remaining ammunition. Additionally, the D-50 can be disassembled quickly with a simple flat blade screwdriver, and a has a dot matrix pattern that allows for easy marking and identification. At approximately 1.5 lbs. empty, and 4.5 lbs. loaded, the Magpul D-50 is one of the lightest 50-round 7.62×51/.308 drums available and is priced well below current competition.

Designed specifically for 7.62×51 NATO/.308 Winchester ammunition and use with other calibers such as .260 Remington or 6.5 Creedmoor is not recommended.

    • I’ll buy some Magpuls for my 5.56 Mini.
      Gun Mag Warehouse has Ruger 20’s for $30 and 30’s for $36 which is kind of pricey in my world.
      Tried different after market brands and they didn’t work as well as the Ruger mags.

  1. Why would I pay $149 for a 50 round drum compared to 8-30 round PMags Windows for $149 holding 240 rounds? One malfunction of the drum and you are screwed. One malfunction of the 30 rnd mag and you have 7 more to use. Just my point of view.
    I’m a Fmr Army Special Forces A-Team E-5 and LEO SWAT team member.

  2. With a dozen 25rd, a dozen 20rd, and a pair of 10rd LR/SR GEN M3 PMAGs onhand, I HARDLY needed MORE mags for my POF P308 Gen4 EDGE SPR AR-10, yet I picked up the D50 Drum mag anyway.

    I had the chance to use a friends D50 drum mag at a range session and really liked it. He has put over 1000rds thru it with flawless operation.

    Well done Magpul, didn’t need it, but HAD to have it.
