The Magpul PMAG D-50 LR/SR 50-Round Drum Magazine

The Magpul PMAG D-50 LR/SR 50-round drum magazine represents a significant leap forward in high-capacity feeding devices for compatible 7.62x51 NATO (.308 Winchester) firearms. Designed specifically for SR25 and M110 pattern rifles, this innovative drum addresses the persistent demand from shooters for increased firepower, reduced reload times, and uncompromising reliability in a durable, user-friendly package. Whether you're a competitive shooter looking to gain an edge, a tactical professional requiring extended engagement capabilities, or a recreational enthusiast seeking more uninterrupted range time, the D-50 stands as a premier solution, engineered to seamlessly integrate with your existing setup and elevate your shooting experience.

Unlocking Extended Performance: Why High-Capacity Matters

For many rifle owners, the limitations of standard 20 or 25-round magazines become apparent during extended shooting sessions, competitive stages, or tactical scenarios. The need for frequent reloads can disrupt focus, slow down performance, and potentially compromise safety in dynamic environments. The Magpul PMAG D-50 directly solves this challenge by offering an impressive 50-round capacity, effectively doubling or even tripling the firepower available before requiring a magazine change. This translates directly to:

• Reduced Reload Interruptions: Enjoy longer periods of continuous firing, crucial for maintaining rhythm in competition or sustained engagement in critical situations.
• Enhanced Tactical Advantage: In defensive or tactical applications, having a higher round count can provide a decisive edge, allowing you to maintain suppressive fire or address multiple threats without interruption.
• Optimized Range Time: Spend more time shooting and less time reloading at the range, making your practice sessions more efficient and enjoyable.
• Superior Competitive Performance: For disciplines like 3-Gun or precision rifle matches, minimizing reloads can shave precious seconds off your stage times, contributing to better overall scores.

This capacity is not just about quantity; it's about optimizing the shooting experience by reducing a common point of interruption and increasing operational efficiency.

Precision Engineering: A Deep Dive into the D-50’s Core Features

The Magpul PMAG D-50 LR/SR is a testament to Magpul's commitment to innovation and quality. Every aspect of its design has been meticulously crafted to ensure maximum performance and longevity.

• Next-Generation Impact and Crush-Resistant Polymer Construction: At the heart of the D-50's resilience is its advanced polymer construction. Unlike traditional steel or aluminum magazines, the D-50 utilizes Magpul's proprietary polymer blend, known for its exceptional durability. This material is not only lightweight, reducing overall rifle weight compared to a similarly sized metal drum, but also incredibly resistant to impact, drops, and crushing forces. This ensures the magazine maintains its structural integrity even in harsh operational environments, providing reliable feeding even after significant abuse. It also resists corrosion, a common issue with metal magazines exposed to moisture and varied climates.
• Robust Stainless Steel Internals: While the exterior boasts cutting-edge polymer, the internal mechanisms are fortified with robust stainless steel components. This critical combination ensures that the high-stress areas, such as the spring mechanism and follower guides, can withstand the rigorous demands of holding and feeding 50 rounds of 7.62x51 NATO ammunition. Stainless steel provides superior corrosion resistance and maintains spring tension over extended periods, contributing significantly to the D-50's long-term reliability and consistent feeding. This blend of materials leverages the best properties of each: the flexibility and impact absorption of polymer with the strength and wear resistance of steel.
• Ratcheting Loading Lever for Effortless Assembly: Loading drum magazines can often be a cumbersome and time-consuming task, especially with high-capacity designs. The Magpul D-50 addresses this pain point directly with an integrated ratcheting loading lever. This innovative feature significantly eases the loading process, allowing users to effortlessly compress the spring and insert rounds without excessive force or specialized tools. The ratcheting mechanism holds the spring under tension as you load, preventing the sudden release of pressure and making the process smooth and controlled. This is a game-changer for anyone who has struggled with manual drum loading, transforming a chore into a quick and efficient procedure.
• High-Visibility Follower: A bright, high-visibility anti-tilt follower is a crucial component within the D-50. This orange-colored follower serves multiple purposes: it provides a clear visual indicator when the magazine is empty, preventing dry firing and signaling the need for a reload. More importantly, its anti-tilt design ensures consistent and reliable feeding of ammunition into the rifle's chamber, preventing common malfunctions such as nosedives or failures to feed. This small but vital feature reinforces the D-50's commitment to unwavering reliability.
• Round-Remaining Window: Practicality is paramount in tactical and competitive settings. The D-50 incorporates a transparent round-remaining window, allowing shooters to quickly and accurately assess their ammunition count at a glance. This feature eliminates the guesswork associated with traditional opaque magazines, enabling better situational awareness and more strategic decision-making regarding reloads. Knowing precisely how many rounds you have left can be critical in high-stress situations, ensuring you don't run dry unexpectedly.

Unmatched Compatibility: Designed for the AR-10 Platform

The Magpul PMAG D-50 is engineered specifically for compatibility with SR25/M110 pattern rifles, chambered in 7.62x51 NATO (.308 Winchester). This includes a wide array of popular AR-10 style firearms from various manufacturers that adhere to the SR25 magazine pattern.

• SR25/M110 Rifles: These platforms are renowned for their accuracy and power, making them ideal candidates for a high-capacity drum magazine that can fully leverage their capabilities. The D-50 ensures a precise fit and reliable feeding in these demanding systems.
• 7.62x51 NATO / .308 Winchester: This dual caliber compatibility ensures versatility for users who might interchange between military-spec 7.62x51mm ammunition and commercial .308 Winchester rounds. The D-50 is designed to feed both reliably, accommodating the slightly different dimensions of each type of cartridge without compromise.

This dedicated compatibility means you can trust the D-50 to integrate flawlessly with your existing SR25 or M110 pattern firearm, delivering the consistent performance Magpul is known for.
