Lyman Mossberg 590 +5 Rounds Shotgun Magazine Extension Review

What Makes Lyman Mossberg 590 +5 Rounds Shotgun Magazine Extension Stand Out?

The Lyman Mossberg 590 +5 Rounds Shotgun Magazine Extension promises to boost the capacity of your trusty Mossberg 590, transforming it into an even more formidable defensive or tactical tool. Manufactured by Lyman, this extension claims to offer enhanced firepower and faster follow-up shots. It’s a tempting upgrade, but does it live up to the hype?

I’ve always believed in maximizing the potential of my firearms, especially when it comes to home defense. The standard capacity of my Mossberg 590 felt limiting; more rounds mean less reloading in a critical situation. I needed a reliable and robust extension that wouldn’t compromise the shotgun’s balance or function.

My first impression upon unboxing the Lyman Mossberg 590 +5 Rounds Shotgun Magazine Extension was generally positive. The aluminum construction felt solid, and the black finish matched my 590’s aesthetic nicely. The extension wasn’t overly heavy, which was a relief, suggesting it wouldn’t drastically alter the shotgun’s handling.

I considered the TacStar and Nordic Components extensions, both reputable brands in the shotgun accessory market. Ultimately, I chose the Lyman extension due to its competitive price point and the reputation of Lyman for producing reliable reloading equipment. It seemed like a good balance of quality and value.

Initially, I was optimistic but also a bit skeptical. Magazine extensions can sometimes introduce feeding issues or negatively impact the shotgun’s balance. I was hoping the Lyman Mossberg 590 +5 Rounds Shotgun Magazine Extension would prove to be a seamless and effective upgrade, enhancing my 590’s capabilities without any drawbacks.


Real-World Testing: Putting Lyman Mossberg 590 +5 Rounds Shotgun Magazine Extension to the Test

First Use Experience

I first tested the Lyman Mossberg 590 +5 Rounds Shotgun Magazine Extension at my local outdoor shooting range, a controlled environment where I could safely assess its performance. I ran a variety of ammo through it, from birdshot to buckshot, to check for any feeding issues or malfunctions. The weather was clear and sunny, ideal conditions for getting a feel for the extended capacity.

The initial installation was straightforward, thanks to clear instructions, and it integrated seamlessly with my Mossberg 590. The added weight at the front was noticeable but manageable; it took a few rounds to adjust my grip and stance. I did notice a slight hesitation in the feeding cycle with some of the cheaper birdshot, but overall, the extension performed reliably.

It did take me a few magazines to get used to the added length and weight, especially during rapid-fire drills. The longer magazine tube affected the shotgun’s swing and maneuverability. Despite this adjustment period, the increased capacity was a significant advantage, allowing for longer strings of fire without needing to reload.

The only real issue I encountered initially was a slight loosening of the extension tube after about 50 rounds of buckshot. I tightened it back up, and it seemed to hold after that, but it was something I kept an eye on. This highlighted the importance of proper tightening and regular maintenance to ensure reliable operation.

Extended Use & Reliability

After several months of regular use, the Lyman Mossberg 590 +5 Rounds Shotgun Magazine Extension has proven to be a generally reliable addition to my Mossberg 590. I’ve used it in various scenarios, from recreational shooting to home defense drills, and it has consistently performed well. The initial loosening issue hasn’t resurfaced, likely due to careful tightening and thread locking.

Signs of wear and tear are minimal, mainly some slight scuffing on the finish from handling and storage. The aluminum construction has held up well to the repeated recoil of heavy loads. I’ve made sure to clean the extension tube regularly, removing any powder residue or debris to maintain smooth feeding.

Maintenance is simple: a quick wipe-down after each range session and a more thorough cleaning every few months. Compared to my experience with some cheaper magazine extensions, the Lyman extension is far more durable and reliable. It gives me confidence that it will perform when I need it most.

The Lyman Mossberg 590 +5 Rounds Shotgun Magazine Extension definitely outperforms other budget options I’ve tried in the past. It has enhanced the firepower of my Mossberg 590 without sacrificing reliability or significantly impacting handling. While not perfect, it’s a solid and worthwhile upgrade.
