ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine Review

First Impressions of ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine

The ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine promises a significant increase in firepower for your AR-15, and it’s the kind of product that immediately grabs your attention. With a 65-round capacity, this drum magazine aims to eliminate frequent reloads, offering a tactical advantage or simply extended range time. The drum magazine is manufactured by ProMag and constructed with DuPont Zytel polymer.

My interest in high-capacity magazines stems from participating in several 3-gun competitions. Constantly reloading mid-stage was costing me valuable time. I needed a reliable solution to minimize interruptions and maximize my shooting efficiency.

Upon unboxing, the ProMag drum felt surprisingly lightweight, a positive sign considering its capacity. The Zytel polymer construction felt robust, although I noted a slightly less refined finish compared to my Magpul PMAGs. The spring tension felt strong, giving me confidence in its feeding capability, although I have read there are issues regarding this.

Compared to a Beta C-Mag or X Products X-15, the ProMag offered a more budget-friendly option. The price point was a major factor in my decision, as I wanted to experiment with a drum magazine without breaking the bank. I was both excited and cautiously optimistic, knowing that high-capacity magazines can sometimes be finicky.

Real-World Testing: Putting ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine to the Test

First Use Experience

My initial test took place at my local outdoor shooting range, under relatively mild conditions – sunny, with a slight breeze. I loaded the ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine with 55 grain .223 ammunition and inserted it into my AR-15. The first few rounds fed without issue.

Unfortunately, by round ten, I experienced a failure to feed. After clearing the malfunction, I continued firing, only to encounter similar issues every few rounds, which was extremely frustrating.

Extended Use & Reliability

After several range sessions spanning a couple of months, the ProMag drum continued to present reliability challenges. While it occasionally cycled through a full load with no issues, malfunctions remained frequent, especially when fully loaded. The DuPont Zytel polymer showed no signs of physical wear or cracking, but the feeding issues persisted.

Cleaning the magazine was relatively straightforward. I used a standard magazine brush and solvent to remove any fouling. However, the internal spring mechanism seemed to be the primary culprit behind the malfunctions, regardless of cleanliness. Compared to my experience with PMAGs and Lancer magazines, the ProMag fell short in terms of reliability and consistent performance.

Breaking Down the Features of ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine

Specifications

• The ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine is designed for AR-15 platforms chambered in 5.56x45mm NATO/.223 Remington. This is the standard AR-15 round, making it widely compatible.

Performance & Functionality

The ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine aims to provide increased firepower and reduced reloading frequency. The initial failures to feed were a major disappointment. While the ProMag can function, its inconsistent performance makes it unreliable for serious use.

Design & Ergonomics

The DuPont Zytel polymer construction makes the drum relatively lightweight for its capacity. However, the large size and shape of the drum can make it somewhat cumbersome to handle and maneuver, especially when shooting from prone or supported positions. There is no real learning curve, it is just inserting a magazine.

Durability & Maintenance

The DuPont Zytel polymer construction appears to be durable, and the magazine body has withstood moderate use without cracking or showing significant wear. Disassembly for cleaning is relatively straightforward, making maintenance manageable. Regular cleaning and lubrication are recommended to maintain optimal performance.

Accessories and Customization Options

The ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine does not come with any specific accessories. It’s designed to be a standalone magazine solution. Due to its unique drum shape, it is not directly compatible with magazine couplers or other magazine accessories designed for standard AR-15 magazines.

Who Should Buy ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine?

The ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine might be suitable for recreational shooters who prioritize high capacity and are willing to tolerate occasional malfunctions. It also might be suitable for those looking for a range toy to burn through a lot of ammo quickly.

However, it is not recommended for anyone who needs guaranteed reliability, such as law enforcement, military personnel, or competitive shooters where malfunctions can cost valuable time. Given the reported issues from users and my own experience, I cannot recommend it for defense.

Conclusion on ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine

The ProMag AR-15 65 Round 5.56x45mm Drum Rifle Magazine promises high capacity at an attractive price point. Unfortunately, my experience, coupled with other user feedback, suggests that reliability is a significant concern.

While the durable polymer construction and high capacity are appealing, the frequent malfunctions overshadow these benefits. For critical applications, investing in more reliable magazine options is strongly recommended. I would not personally recommend the ProMag drum magazine unless you’re willing to accept its inherent limitations and potential for malfunctions. Proceed with caution and test thoroughly before relying on it.
