Aimtech 2pc Low Rib Rider for Mossberg 500, 590, 835, 91, 87 Review

Here’s What I Think of the Aimtech 2pc Low Rib Rider for Mossberg 500, 590, 835, 91, 87

As someone who’s spent over a decade wrestling with gear in every imaginable environment, from delicate lab setups to unforgiving outdoor expeditions and demanding workshop tasks, I’ve developed a keen eye for what works and what’s just taking up space. When I encountered the Aimtech 2pc Low Rib Rider for Mossberg 500, 590, 835, 91, 87, it was born out of a specific need: mounting a red dot sight onto a Mossberg shotgun without adding significant bulk or compromising the firearm’s profile. The sheer variety of shotgun optics mounts can be overwhelming, and finding one that truly integrates seamlessly is a challenge. Many solutions are clunky, elevate the sight too much, or require drilling and tapping, which I prefer to avoid.

My initial impression upon unboxing was one of practical elegance. The mounts felt solid, with a satisfying weight that spoke of quality materials rather than cheap pot metal. The precision machining was immediately apparent in the crisp edges and smooth finish. I had briefly considered a few other brands, mostly generic options found online, but none offered the same specific design approach or the promise of a low profile. This Aimtech system, with its two-piece construction designed to clamp onto the rib, offered a compelling alternative. My first reaction was a quiet sense of anticipation; this looked like a well-thought-out piece of equipment that might just solve my mounting dilemma.

Real-World Testing: Putting Aimtech 2pc Low Rib Rider for Mossberg 500, 590, 835, 91, 87 to the Test

First Use Experience

My testing ground for this particular piece of equipment was, naturally, my favorite shooting range and the occasional duck blind. The primary objective was to attach a standard Weaver-style reflex sight to my Mossberg 590A1. The installation process itself was straightforward. The two pieces of the mount, once positioned on either side of the shotgun’s rib, clamped down securely with the provided screws. I appreciated how they wrapped around or butted up against the rib pillars, offering a very stable platform without any wobble.

During extended range sessions, which involved firing upwards of 50 rounds of 12-gauge slugs and buckshot, the mounts performed admirably. They held zero consistently, and the sight remained firmly in place even with the recoil inherent in shooting a shotgun. I even experienced an unexpected dust storm at the range one afternoon, which coated everything, and these mounts held up with no discernible performance drop. Their low-profile design was a significant advantage, keeping the sight line comfortable and preventing any snagging issues when moving the shotgun.

Extended Use & Reliability

After several months of use, spanning multiple hunting seasons and countless practice sessions, the Aimtech 2pc Low Rib Rider for Mossberg 500, 590, 835, 91, 87 have proven to be incredibly reliable. I’ve subjected them to damp conditions, the occasional drop (landing on soft earth, thankfully, but still a test), and the general grime that comes with regular firearm use. There are absolutely no signs of wear and tear, such as cracks, stiffness in the clamp mechanism, or any loosening of the screws.

Cleaning and maintenance are refreshingly simple. A quick wipe-down with a clean cloth and some mild lubricant is usually all that’s needed to keep the precision extruded and CNC machined aluminum alloy looking and functioning like new. Compared to some other aftermarket mounts I’ve used in the past, which often required frequent re-tightening or developed play after heavy use, these Aimtech units stand out. They offer a level of durability and consistent performance that rivals much more expensive options, making them a fantastic value.

Breaking Down the Features of Aimtech 2pc Low Rib Rider for Mossberg 500, 590, 835, 91, 87

Specifications

The core of these mounts lies in their construction: they are manufactured from precision extruded and CNC machined aluminum alloy. This material choice ensures a good balance of strength and weight, which is crucial for a firearm accessory. The design philosophy is centered on achieving the lowest possible profile, accomplished by having the mounts grip the rib and wrap around or butt up to the rib pillars. This design allows most electronic sights that attach to a Weaver style or a Picatinny style base to be mounted effectively. The finish is a beautiful black Type II anodizing, which meets MIL-SPEC A-8625 standards, offering excellent corrosion and abrasion resistance.

These specifications translate directly into user benefits. The CNC machined aluminum alloy provides the rigidity needed to maintain zero under recoil, preventing the sight from shifting. The lowest possible profile achieved by the unique clamping mechanism means a more natural cheek weld and reduced snagging potential, which is vital for quick target acquisition. The MIL-SPEC Type II anodizing guarantees that the finish will withstand harsh conditions and remain aesthetically pleasing for years. For shotgun users, the compatibility with both Weaver style and Picatinny style bases on optics significantly broadens the range of sights that can be used.

Performance & Functionality

In terms of its primary job – securely mounting an optic to a shotgun rib – the Aimtech 2pc Low Rib Rider for Mossberg 500, 590, 835, 91, 87 excels. The two-piece design provides redundant clamping points, which contributes to exceptional stability. I experienced zero shift in my sight’s point of impact, even after firing a full magazine of buckshot as quickly as I could manage follow-up shots. The low profile design is not just an aesthetic choice; it genuinely improves the shooting experience by allowing for a more comfortable and efficient sight picture.

The main strength of this mount is its ingenious design for rib mounting, offering a solution that is both secure and unobtrusive. Its primary limitation, which is inherent to most rib-mounted systems, is that it’s designed specifically for shotguns with a distinct rib. Users with shotguns lacking a substantial rib would need a different mounting solution. However, for its intended application, it performs flawlessly, exceeding expectations for a product in its price bracket.

Design & Ergonomics

The design of the Aimtech mounts is elegantly functional. The precision extruded and CNC machined aluminum alloy gives them a robust feel, with sharp, clean lines that look as good as they perform. The matte black finish from the Type II anodizing complements most shotgun finishes and resists glare effectively. When installed, the mounts integrate so well with the shotgun’s receiver and barrel that they become almost an extension of the firearm itself, rather than an add-on accessory.

Ergonomically, they are designed to be as unobtrusive as possible. The low profile ensures that the mounted optic sits as close to the bore axis as feasible for a rib-mounted system, which aids in faster target acquisition and a more natural cheek weld. There was no learning curve; the installation was intuitive, and once mounted, they require no further interaction. The secure clamping mechanism means you don’t have to constantly fiddle with adjustments, allowing you to focus entirely on shooting.

Durability & Maintenance

Given their CNC machined aluminum alloy construction and MIL-SPEC Type II anodizing, these mounts are built for longevity. I anticipate they will last the lifetime of the shotgun under normal to heavy use, which is a testament to the quality of materials and manufacturing. The anodized finish is tough and resists scratches and wear far better than many painted or blued alternatives.

Maintenance is minimal, primarily involving periodic checks of the screws for tightness (though they’ve shown no tendency to loosen) and occasional cleaning to remove debris. There are no complex parts to break or wear out. The design inherently protects the clamping screws from impact, further contributing to their durability. If any part were to fail, which seems unlikely, the 2 pc design implies that individual pieces could potentially be replaced, though I haven’t encountered any need for this.

Accessories and Customization Options

The primary function of the Aimtech 2pc Low Rib Rider for Mossberg 500, 590, 835, 91, 87 is to provide a stable mounting platform. Therefore, the “accessories” are largely the optics you choose to attach. They are designed to accept most sights with standard Weaver style or Picatinny style bases. This versatility means you can choose from a vast array of red dot sights, reflex sights, or even small holographic sights.

While there aren’t direct “customization options” for the mounts themselves, their compatibility with industry-standard optic bases is the key customization feature. This allows users to tailor their shotgun’s sighting system precisely to their needs, whether for tactical applications, hunting, or competition shooting. The low profile aspect also means you can often use smaller, lighter optics without drastically altering the shotgun’s balance.
