Overview

The Magpul PMAG Gen M3 20-Round 300 AAC Blackout Magazine is a high-quality, reliable, and affordable magazine designed for use with the 300 AAC Blackout caliber. As a huge fan of the 300 AAC Blackout cartridge, I was excited to get my hands on this magazine and put it through its paces. In this review, I’ll cover my experiences with the PMAG Gen M3, including its performance, build quality, and any notable features or drawbacks.

Design and Build Quality

The Magpul PMAG Gen M3 is a well-made magazine that exudes a sense of quality and attention to detail. The magazine is constructed with a durable polymer body and a stainless steel spring, ensuring a strong and reliable feeding system. The design is sleek and ergonomic, with a contoured grip that makes it easy to handle and use. The magazine’s body also features a series of recessed buttons and ridges to prevent debris and snow from accumulating, which is a great touch.

Performance

I was impressed with the PMAG Gen M3’s performance. It consistently fed and ejected rounds without issue, and I never experienced any failures to feed or extract. The magazine’s stainless steel spring and reliable bolt worked together to ensure a smooth and consistent loading process. I also appreciated the magazine’s ability to handle a variety of ammunition, including both factory-produced and handloaded 300 AAC Blackout rounds.

Capacity and Functionality

The PMAG Gen M3 is designed to hold 20 rounds of 300 AAC Blackout ammunition, which is perfect for target shooting, hunting, or self-defense. The magazine’s ejector system makes it easy to clear the chamber and facilitate a quick reload, and the included tool for releasing the internal magazine spring is a nice touch. I also appreciated the magazine’s compatibility with the Magpul 300 AAC Blackout choke valve, which is designed to expand and contract in response to the expanding 300 AAC Blackout cartridge.

Pros and Cons

  • Reliable and consistent feeding and ejection: The PMAG Gen M3 performed flawlessly, never failing to feed or extract a round even with the most challenging ammunition.
  • Durable construction: The magazine is built to last, with a sturdy polymer body and stainless steel spring that can withstand rough handling and heavy use.
  • Easy to disassemble and clean: The magazine is easy to take apart and reassemble, making maintenance and cleaning a breeze.
  • Affordable: The PMAG Gen M3 is priced competitively with other high-quality 300 AAC Blackout magazines on the market.
  • Some users may find the magazine’s capacity limited: While 20 rounds is a respectable capacity for a 300 AAC Blackout magazine, some users may find it insufficient for extended shooting sessions or high-volume firefights.

Conclusion

The Magpul PMAG Gen M3 20-Round 300 AAC Blackout Magazine is a top-notch choice for anyone looking for a reliable and affordable magazine designed specifically for the 300 AAC Blackout caliber. With its durable construction, consistent feeding and ejection, and easy maintenance, this magazine is sure to please.
