The PRO MOSS500/590 BUTTSTK/CARR Made a Bold First Impression
The PRO MOSS500/590 BUTTSTK/CARR from ProMag promises to modernize the classic Mossberg 500 and 590 shotguns. It features a six-position collapsible buttstock, a 7-round shell carrier, and ambidextrous design. I was eager to swap out the factory stock on my aging Mossberg 500 for something with a bit more tactical flair and adjustability.
My quest for the PRO MOSS500/590 BUTTSTK/CARR began when I wanted to improve the ergonomics and versatility of my home defense shotgun. The original stock, while functional, lacked adjustability, making it difficult to comfortably shoulder with different layers of clothing or for various family members. An adjustable stock seemed like the perfect solution.
Unboxing the PRO MOSS500/590 BUTTSTK/CARR, the first thing I noticed was its substantial weight. The polymer felt robust, and the pistol grip had a comfortable texture. The shell carrier seemed sturdy enough to hold shells securely.
I considered the Magpul SGA stock and the Mesa Tactical LEO adapter with an AR buffer tube, both reputable options. However, the ProMag offered a more complete package with the integrated shell carrier at a more budget-friendly price point. The appeal of having readily accessible extra rounds swayed my decision.
My initial impression was a mix of excitement and slight apprehension. The weight and seemingly solid construction instilled confidence. However, the lack of detailed instructions immediately raised a red flag. I was excited about the potential but cautious about the installation process.
Real-World Testing: Putting PRO MOSS500/590 BUTTSTK/CARR to the Test
First Use Experience
My first experience with the PRO MOSS500/590 BUTTSTK/CARR was at my local shooting range. I spent the afternoon running various drills, including transitioning between targets and practicing reloads using the shell carrier. The adjustability of the stock allowed me to quickly find a comfortable length of pull, even while wearing a heavy tactical vest.
The PRO MOSS500/590 BUTTSTK/CARR performed surprisingly well in dry conditions, but I quickly realized potential issues with the shell carrier in wet environments. During a simulated rain drill (using a garden hose!), the shells became slick, making them difficult to quickly extract from the carrier. This revealed a potential limitation in adverse weather.
The adjustable stock’s ease of use was a major plus. Adjusting the length of pull was intuitive and required no tools, making it simple to adapt to different shooting stances and situations. I had to get used to the slightly different balance of the shotgun with the heavier stock.
After the first range session, I found that the stock had developed a slight rattle, confirming some users reports. The rattle was noticeable during movement, but did not affect the functionality of the stock during firing. I also noticed that the rubber buttpad was somewhat difficult to remove and reseat securely, as mentioned by other users.
Extended Use & Reliability
After several weeks of regular use, the PRO MOSS500/590 BUTTSTK/CARR has held up reasonably well, with some caveats. The polymer stock has shown no signs of cracking or significant wear, despite being subjected to recoil from various 12-gauge loads, from birdshot to slugs. The shell carrier, however, shows wear marks where shells are repeatedly inserted and removed.
The only real sign of wear and tear has been on the shell carrier, where the elastic retention bands have stretched slightly. This has led to a less secure hold on the shells over time. Regular cleaning is relatively straightforward. The stock can be wiped down with a damp cloth, and the shell carrier can be cleaned with a brush to remove any debris.
Compared to my previous experiences with other aftermarket stocks, the PRO MOSS500/590 BUTTSTK/CARR has proven to be a decent performer, but not without its flaws. While it does offer adjustability and a shell carrier at a reasonable price, the issues with rattling and shell retention prevent it from being a top-tier upgrade. It is a noticeable improvement over the factory stock, but doesn’t quite reach the level of more expensive alternatives.

Performance & Functionality
The PRO MOSS500/590 BUTTSTK/CARR enhances the Mossberg 500 and 590 by offering adjustability, improved ergonomics, and increased ammunition capacity. It performs adequately in most scenarios, but its reliability can be affected by environmental conditions.

Who Should Buy PRO MOSS500/590 BUTTSTK/CARR?
The PRO MOSS500/590 BUTTSTK/CARR is perfect for budget-conscious shotgun owners looking for an adjustable stock with an integrated shell carrier.

Conclusion on PRO MOSS500/590 BUTTSTK/CARR
The PRO MOSS500/590 BUTTSTK/CARR is a decent, budget-friendly upgrade for Mossberg 500 and 590 shotguns. It offers adjustable length of pull and an integrated shell carrier, enhancing both ergonomics and tactical capabilities. However, the rattling issue and potential for shells to become slippery in wet conditions detract from the overall experience.
At $67.49, the price is justifiable for the features offered. However, potential buyers should be aware of the limitations and consider whether the benefits outweigh the drawbacks.
I would recommend the PRO MOSS500/590 BUTTSTK/CARR to those on a tight budget who need an adjustable stock with a shell carrier. But I would strongly advise them to address the rattling issue and be prepared for potential difficulties in wet environments. If you are looking for a premium upgrade, explore higher-end options like Magpul or Mesa Tactical.
