If you're running an LR308, SR-25, or similar .308 platform rifle and need serious magazine capacity, the Magpul PMAG D-50 LR/SR Gen M3 50-round drum magazine delivers performance without the weight penalty that typically comes with high-capacity drums. Built on the same proven design foundation as Magpul's legendary PMAG line, this .308 Winchester drum is engineered for durability, dependability, and real-world usability—whether you're at the range, in the field, or running precision drills.
The D-50's standout advantage is its compact overall height: it matches a standard 25-round PMAG profile, which means shooting prone, storing in tight spaces, and handling from different positions feels nearly identical to running a conventional magazine. That's genuine innovation in the precision rifle world. The drum uses a ratcheting loading lever to reduce spring tension and make hand-loading practical, while robust stainless-steel internals resist corrosion even during long-term loaded storage. An anti-glare translucent witness window with a dot-matrix marking pattern lets you quickly assess your ammunition count without breaking position.
At roughly 1.7 pounds empty and 4.5 pounds loaded, the D-50 ranks among the lightest 50-round .308 drums available, keeping your rifle's handling and balance closer to standard than heavier competitors. The magazine accommodates longer-than-SAAMI match ammunition up to 2.830" OAL—think M118LR—making it suitable for precision and match shooting. A slip-on dust cover protects against grit during transport, and disassembly is simple with a flat-blade screwdriver if you ever need to service it.
Keep in mind: the D-50 is optimized for standard AR-10-pattern .308 rifles like the LR308 and SR-25, and is compatible with older Bushmaster .308 ORC, Remington R-25, and DPMS LR308 models. It is not compatible with M14, FN FAL, HK 91/G3, or other non-AR-pattern .308 designs. Use only .308 Winchester or 7.62×51 NATO ammunition; other calibers are not recommended.

Yes. The D-50 accommodates match ammunition and other longer-than-SAAMI-spec rounds up to 2.830\" overall length, including M118LR. This makes it suitable for precision rifle and match shooting applications where longer ammunition is standard.
The D-50's unique compact height matches a standard 25-round PMAG LR/SR profile, giving it nearly identical handling and shootability from prone and other positions compared to conventional magazines. At 1.7 pounds empty and 4.5 pounds loaded, it's also one of the lightest 50-round .308 drums available. The ratcheting loading lever makes hand-loading practical, and the translucent witness window with marking pattern allows quick ammunition count without breaking position.
Yes, the D-50 comes with a slip-on semi-rigid dust cover for storage and transport. The magazine disassembles quickly and easily using a flat-blade screwdriver or similar tool if you need to service or clean it.
