The Magpul PMAG D-50 LR/SR GEN M3 delivers sustained firepower for AR-10 platform rifles with its 50-round drum capacity in 308 Winchester and 7.62x51mm NATO. This polymer drum magazine eliminates frequent reloading during extended range sessions and competition shooting. Built with Magpul's proven GEN M3 technology, it provides reliable feeding and consistent performance across multiple rifle platforms.
What Makes This Different
Unlike standard 20-round AR-10 magazines, this drum configuration stores 2.5 times more ammunition in a single loading cycle. The ratcheting loading lever reduces hand fatigue during magazine loading compared to traditional spring-loaded systems. Constructed from impact-resistant polymer, it weighs significantly less than steel drum alternatives while maintaining structural integrity under field conditions. The translucent rear window allows quick round count verification without magazine removal.
Key Features
- 50-round capacity reduces reload frequency during extended shooting sessions
- Ratcheting loading mechanism simplifies ammunition loading process
- Impact-resistant polymer construction withstands field use and storage
- Translucent rear window enables visual round count confirmation
- GEN M3 follower technology ensures consistent cartridge presentation
- Compatible with AR-10, M110, SR-25, and similar 7.62x51mm rifles
- Self-lubricating materials reduce maintenance requirements
Field testing demonstrates reliable cycling across various rifle configurations and environmental conditions. The drum's low profile maintains shooting positions without interference, while the robust spring system maintains consistent tension throughout the entire capacity range. Competition shooters benefit from reduced stage times, while tactical applications gain extended engagement capability without magazine changes.
