Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights Review

It’s Time to Talk About the Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights

As an equipment specialist with over a decade of hands-on experience across diverse environments, I’ve developed a keen eye for what works and what doesn’t. My search for a more adaptable barrel for my existing 835 platform led me to the Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights. This barrel, specifically designed for slug use with adjustable sights, promised enhanced accuracy and versatility for various shooting applications.

The need for this specific barrel arose from a desire to improve my rifled slug shooting capabilities without investing in an entirely new shotgun. My previous barrel, while functional, lacked the adjustability crucial for dialing in precise shots at extended distances. I considered a dedicated slug gun but ultimately decided a barrel replacement offered a more cost-effective and practical solution for my needs.

Upon initial inspection, the barrel presented a solid, well-finished appearance. The blued finish felt robust, and the adjustable sights seemed well-integrated into the design. My first impression was one of practical utility, a tool built for a specific, demanding purpose.

Real-World Testing: Putting Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights to the Test

My initial testing took place on a familiar outdoor range, where I could establish a baseline for accuracy with various slug loads. I mounted the barrel onto my Mossberg 835 receiver and proceeded to zero the adjustable sights. The conditions were fair, with light wind and mild temperatures, ideal for initial assessment.

The ease of zeroing was a notable advantage. The adjustable sights offered clear detents and a satisfying click with each adjustment, making fine-tuning straightforward. I experienced no immediate issues, and the barrel mounted securely, integrating seamlessly with my receiver.

After several weeks of regular use, including multiple range visits and a few field excursions for pest control, the barrel continues to perform admirably. It has held its zero consistently, even after being subjected to the vibrations of transport and repeated firing. The blued finish, while showing minor handling marks, has resisted significant wear, indicating good material quality.

Maintenance has been minimal, primarily involving a quick wipe-down and occasional light oiling after range sessions. Compared to some aftermarket barrels I’ve used, this Mossberg unit feels exceptionally robust. It lacks the flimsy feel of some budget options and possesses a durability that suggests it will last for many seasons to come.

First Use Experience

My first range session was crucial for dialing in the Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights. I mounted it onto my established 835 receiver, ensuring a tight fit, and proceeded to test various 2 ¾” and 3” rifled slugs. The adjustable sights allowed for a methodical process of sighting in, and I was pleased with how quickly I could achieve a consistent group.

I tested this barrel primarily on a local outdoor shooting range, focusing on static target practice out to 100 yards. The 24″ length proved to be a good balance between maneuverability and projectile velocity. I also utilized it for some informal prairie dog control, where the quick target acquisition provided by the sights was invaluable.

The adjustable sights were intuitive to use, with clearly marked adjustments for elevation and windage. I did not encounter any initial operational quirks; the barrel fit snugly and functioned flawlessly with the receiver. The cylinder bore design is also worth noting, as it’s ideal for the intended use with rifled slugs.

Extended Use & Reliability

Over several months, this barrel has become a staple for my slug-shooting needs. It has endured numerous trips in my vehicle, exposure to dust, and occasional light rain without any degradation in performance. The blued finish has held up well, showing only minor cosmetic scuffs from handling, not indicative of any structural weakness.

Reliability has been exceptional. The barrel consistently shoots where it’s aimed, and the adjustable sights have maintained their zero even after being bumped lightly during transport. I haven’t noticed any stiffness in the action or any significant drop in accuracy with different slug brands or velocities.

Cleaning is straightforward; a simple bore snake and some solvent suffice for routine maintenance. The fixed choke, being a cylinder bore, makes cleaning even simpler, as there are no chokes to manage. The overall durability is impressive for a component at this price point.

Breaking Down the Features of Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights

Specifications

The Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights is an accessory barrel designed for the Mossberg 835 platform, specifically tailored for 12 gauge shotshells. Its 24-inch length is a key specification, striking a balance between obtaining sufficient velocity from slugs and maintaining reasonable handling characteristics. The barrel features a blued finish, which offers a degree of corrosion resistance and a classic aesthetic.

Crucially, this model includes adjustable sights. These are not mere iron sights; they allow for precise adjustments in both windage and elevation, a significant advantage for slug gun accuracy. The cylinder bore is another important specification, indicating that the barrel is not rifled internally, making it optimized for use with rifled slugs, which are designed to stabilize using their own spin imparted by the shotgun’s bore.

The overall build quality of the Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights feels substantial. The metal is smooth and free of machining marks, and the sights are securely mounted, giving confidence in their durability. This barrel is essentially a direct replacement or upgrade for an existing Mossberg 835 shotgun, designed to enhance its slug-shooting capabilities.

Performance & Functionality

In its primary role as a slug barrel, this component performs exceptionally well. The 24-inch cylinder bore design, combined with adjustable sights, delivers reliable accuracy with a variety of rifled slugs. I’ve consistently achieved sub-4-inch groups at 100 yards with premium slugs, a testament to its design and manufacturing precision.

The biggest strength of this barrel is undoubtedly the adjustable sight system. It allows for much finer tuning than fixed sights, enabling shooters to compensate for different slug weights and velocities. The only minor drawback is that it is optimized for rifled slugs, meaning saboted slugs designed for rifled barrels might not perform as well.

For its intended purpose, the Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights not only meets but often exceeds expectations. The ability to accurately place shots with a pump-action shotgun at distances previously challenging is a significant functional upgrade. It transforms the 835 into a more capable slug gun for hunting or tactical applications.

Design & Ergonomics

The design of this Mossberg barrel is driven by practicality. The blued finish is attractive and provides decent protection against the elements, though it’s not impervious to scratching with rough handling. The 24-inch length contributes to a balanced feel when shouldered, making it comfortable to carry in the field.

Ergonomically, the adjustable sights are well-designed, offering clear aiming points without being overly complex. The sight radius is ample, contributing to easier target acquisition and more precise aiming. The mounting system, integrating directly with the Mossberg 835 receiver, is robust and requires no special tools for attachment.

The overall construction feels solid and purpose-built. There are no superfluous aesthetic elements; every feature serves a functional purpose. The cylinder bore configuration simplifies the design and maintenance, focusing on reliable slug performance.

Durability & Maintenance

This barrel is built to last. The materials and construction suggest it can withstand regular use in various outdoor conditions without premature failure. The blued finish, while not indestructible, offers good corrosion resistance for a component exposed to the elements.

Maintenance is refreshingly simple. A quick cleaning after each use, especially with slug residue, is all that’s typically required. The cylinder bore means no need to worry about damaging rifling or dealing with complex choke tubes, which simplifies the cleaning process considerably.

While I haven’t encountered any specific failure points, common sense dictates avoiding excessively rough handling that could damage the adjustable sights. The barrel itself is robust, but the delicate mechanisms within the sights require some care. Overall, it presents as a highly durable component for its intended use.

Accessories and Customization Options

The primary “accessory” integrated into this barrel is its adjustable sights. These sights are a critical functional component, allowing for significant customization of aiming points. Beyond the sights themselves, there are no other included accessories as this is a replacement barrel.

However, the nature of the Mossberg 835 platform means that other customizations are possible through the receiver and stock. The barrel itself is designed to work with standard 12 gauge rifled slugs. While it features a cylinder bore, it’s not designed for saboted slugs meant for rifled barrels; using such slugs would be a misuse of the product.

The Mossberg 90800 835 12 Gauge 24″ Blue Adj Sights is a self-contained unit in terms of its specific function, with the sights being its key integrated feature.
