First Thoughts on the Knoxx SpecOps Stock Gen III for 12 Gauge Mossberg 500 Black
The Knoxx SpecOps Stock Gen III for 12 Gauge Mossberg 500 Black promises a significant reduction in felt recoil for the popular Mossberg 500 shotgun. This adjustable stock, manufactured by Knoxx, claims to lessen recoil by up to 80%, adapt to various shooters, and provide multiple sling mounting points, all while being proudly made in the USA. As someone who’s put countless rounds through various shotguns over the last decade, including many Mossberg 500s in demanding conditions, I was eager to see if this stock lived up to its bold claims, especially given some conflicting user feedback.
Years of tactical training and hunting have left my shoulder a bit worse for wear, so recoil reduction is a major selling point for me. I was looking for a stock that could tame the 12-gauge beast, allowing for quicker follow-up shots and less fatigue during extended training sessions.
My initial impression upon unboxing was positive. The stock felt solid, with a reassuring weight that spoke to its quality materials; the black finish looked clean and professional. This version replaced a standard fixed stock on one of my go-to Mossberg 500s, a shotgun I’ve relied on for home defense and occasional sporting clays. I’d previously considered the Magpul SGA stock and the Mesa Tactical Urbino stock, both excellent options, but the Knoxx SpecOps Stock Gen III‘s recoil reduction claim and adjustable length of pull swayed me, hoping for a less punishing shooting experience. I was cautiously optimistic, hoping the recoil reduction wasn’t just marketing hype.
Real-World Testing: Putting Knoxx SpecOps Stock Gen III for 12 Gauge Mossberg 500 Black to the Test
First Use Experience
My first outing with the Knoxx SpecOps Stock Gen III was at my local shooting range, under relatively mild weather conditions. I ran a mix of birdshot, buckshot, and slug loads through my Mossberg 500 to get a feel for the stock’s performance across different recoil levels. Installation was straightforward, and the included tool for the grip locknut was a nice touch.
Initially, I was underwhelmed. The recoil reduction, while present, didn’t feel as dramatic as advertised, especially with heavier loads. The adjustable stock positions were a plus, allowing me to find a comfortable length of pull. I immediately noticed that even at the softest setting that I experienced an increase in felt recoil over that of the original stock.
Extended Use & Reliability
After several range sessions and a few training drills in varying weather conditions, I have a more complete picture of the Knoxx SpecOps Stock Gen III. While the adjustability remains a significant advantage, the durability and recoil reduction fall short of expectations. I still noticed significant bruising on my shoulder after firing heavier loads; the stock didn’t provide the promised 80% recoil reduction.
I haven’t noticed any significant wear and tear, though the buttstock tensioner seems to loosen slightly after extended use. Maintenance is simple, requiring only occasional cleaning with a damp cloth. Compared to my other shotguns with standard stocks and aftermarket recoil pads, the Knoxx SpecOps Stock Gen III offers minimal improvement in recoil mitigation, making it a disappointing experience overall. This is especially troubling given the increased felt recoil.
Breaking Down the Features of Knoxx SpecOps Stock Gen III for 12 Gauge Mossberg 500 Black
Specifications
The Knoxx SpecOps Stock Gen III for 12 Gauge Mossberg 500 Black is designed specifically for the Mossberg 500 12-gauge shotgun. It features an adjustable length of pull with six different positions to accommodate various shooters. The stock is made in the USA.
It also includes an integrated buttstock tensioner to eliminate rattle and multiple ambidextrous sling mounting locations for versatile carry options. The Knoxx SpecOps Stock Gen III‘s primary selling point is its claim to reduce felt recoil by up to 80 percent, promising a more comfortable shooting experience.
Performance & Functionality
The functionality of the Knoxx SpecOps Stock Gen III is a mixed bag. While the adjustable length of pull is beneficial for tailoring the shotgun to different body types and shooting styles, the recoil reduction is significantly less effective than advertised. It is unreliable in reducing recoil, and instead increases the felt recoil from the weapon.
The buttstock tensioner does a decent job of minimizing rattle. Sling mounting options are well-placed and ambidextrous, catering to both right- and left-handed shooters.
Design & Ergonomics
The build quality of the Knoxx SpecOps Stock Gen III is generally solid. The materials feel durable and well-made, although the overall weight does add to the shotgun’s heft. The ergonomics are decent, with a comfortable pistol grip and a relatively smooth stock adjustment mechanism.
The stock’s black finish is aesthetically pleasing. It blends seamlessly with the Mossberg 500’s existing components. However, the recoil pad could be improved to better absorb impact.
Durability & Maintenance
The Knoxx SpecOps Stock Gen III appears reasonably durable. It withstands regular use without showing immediate signs of wear and tear. The stock is easy to clean.
This requires only wiping down with a cloth and occasional lubrication of the adjustment mechanism. Long-term reliability remains to be seen, but the initial impression is that it should hold up well under moderate use.
Accessories and Customization Options
The Knoxx SpecOps Stock Gen III doesn’t come with a plethora of accessories, focusing primarily on the stock itself and the necessary installation hardware. The integrated sling mounting points provide some customization in terms of carry options.
The stock is compatible with most standard Mossberg 500 accessories. These include aftermarket shell holders and tactical slings. No additional customization or accessories were included.
