The PMAG D-50 is built for AR-10 and SR-25 pattern rifles, giving you a 50-round option that doesn't force you to compromise on handling. Unlike older drum designs that feel awkward and unreliable, this one feeds consistently and seats smoothly even on a closed bolt. That means no babying your magazine during load-ups or worrying about function issues downrange.
The key to how well this magazine performs comes down to Magpul's GEN M3 polymer construction combined with stainless-steel internals. Impact and crush resistance matter when you're running a high-capacity drum, and the materials here stand up to it. The stainless guts also handle long-term storage while fully loaded without spring fatigue or reliability drop-off.
What makes this drum different from competitors is the drum configuration itself. Magpul engineered it to maintain roughly the same height profile as a standard 25-round PMAG, so shooting prone, from barricades, or during transitions isn't any different than running smaller magazines. Storage is easier too, and you get access without the bulk that comes with other 50-round designs.
A ratcheting loading lever removes the spring tension as you load, which means less hand fatigue and no fighting the magazine while filling it. The anti-glare translucent rear window lets you do a quick visual count of remaining rounds. Field-stripping is straightforward with a flat-blade screwdriver if you ever need to service it. The included dust cover keeps grit out during transport and storage.
The D-50 accepts longer-than-SAAMI-spec ammunition up to 2.830 inches overall length, which matters if you're running match-grade rounds like M118LR. Standard commercial and military spec ammo feeds fine too, giving you flexibility in what you load.
The D-50 is designed for AR-10, M110, and SR-25 pattern rifles. It's compatible with DPMS, LaRue OBR, and standard SR-25 pattern rifles. If your AR-10 is built on one of these patterns, the magazine will fit and function reliably. Some older Bushmaster, Remington, or original DPMS models may not optimize bolt lock functionality, but the magazine will still feed and chamber rounds.
Yes. The D-50 has a ratcheting loading lever that removes spring tension as you load, making hand-loading significantly easier than traditional drum magazines. It does require a bit more effort than loading a standard box magazine, but it's manageable and the lever does most of the work for you.
The D-50's design keeps it at roughly the same height profile as a 25-round PMAG, so shooting prone or from various positions feels normal instead of awkward. Magpul used GEN M3 technology with impact-resistant polymer and stainless-steel internals, which means reliability and consistency that you can count on. It also seats on a closed bolt without issues, feeds match-grade ammo up to 2.830 inches, and is designed to stay loaded long-term without losing function.
Yes. The D-50 accepts ammunition up to 2.830 inches overall length, which covers match-grade rounds like M118LR. It works with standard commercial and military-spec ammunition too, giving you flexibility in what you load depending on your application.
