Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized Review

What I Wish I Knew Before Buying the Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized

As someone who spends a considerable amount of time calibrating optics for precision shooting, finding the right mounting solution is paramount. The Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized caught my eye as a potential upgrade for my rimfire rifle. It promised a solid, no-nonsense base for optics, specifically designed to alleviate issues with achieving zero at shorter distances. What initially drew me in was its reputation for quality from Ruger, a name synonymous with reliable firearm components.

The specific scenario that pushed me towards this component was a persistent problem with my existing scope mount. I found myself frequently bottoming out the turrets on my scope when trying to zero my rifle at closer ranges, typically 25 to 50 yards. This severely limited my ability to effectively use the rifle for its intended purpose, which often involves rapid target acquisition at these intermediate distances. It was a frustrating limitation that needed a more fundamental solution than just adjusting scope ring height.

My first impression upon handling this scope base was one of robust construction. The billet aluminum felt substantial, and the black hard coat anodized finish was even and free of imperfections. It immediately conveyed a sense of durability and a commitment to quality that I appreciate in equipment. It feels like a piece designed to withstand the rigors of regular use without complaint.

While I didn’t extensively research many direct alternatives, I did briefly consider generic aluminum Picatinny rails from other accessory manufacturers. However, the allure of a manufacturer-matched component, especially one from Ruger for their own Precision Rimfire line, steered me towards this option. It seemed like the most straightforward path to a guaranteed fit and finish.

The initial feeling upon acquiring this scope base was one of quiet optimism and a sense of having addressed a critical equipment bottleneck. It felt like a step in the right direction for achieving better accuracy and flexibility with my setup.

Real-World Testing: Putting Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized to the Test

First Use Experience

My testing primarily took place at my local indoor and outdoor shooting ranges. The goal was to evaluate the Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized under typical rimfire shooting conditions. This included shooting from a bench rest at distances ranging from 25 to 100 yards, focusing on the ability to achieve a proper zero without scope limitations. I also subjected it to the typical handling associated with range days, which involves mounting and dismounting optics.

During this initial phase, the conditions were fairly controlled – no extreme weather or significant dust. The primary performance metric was its ability to facilitate a zero at shorter distances. I specifically sought out the frustration I experienced previously, and thankfully, it was entirely absent.

The ease of use was immediately apparent. This is a simple component, a one-piece design that interfaces directly with the rifle’s receiver. Mounting it was straightforward, requiring only the included TORX mounting screws and a T-10 wrench. It slotted perfectly into place, and the Picatinny slot-and-rail spacing offered a secure grip for my scope rings.

One of the most significant positive surprises was the complete elimination of the turret-bottoming issue. The 0 MOA cant, compared to the stock rail I was using, made a tangible difference. It allowed my scope to have ample adjustment range downwards, making a 25-yard zero easily achievable and allowing for a wider effective range without compromising close-in accuracy.

Extended Use & Reliability

Over several months of consistent use, this Ruger scope base has proven its worth. It’s been mounted and dismounted multiple times as I experimented with different optics, and each time, the fit remains snug and secure. I’ve taken it out in light drizzle and encountered the usual workshop dust, and it has shown no adverse effects.

Durability has been excellent. The hardcoat anodized finish shows no signs of significant wear or tear, even around the mounting surfaces where screws have been tightened and loosened. There are no cracks, no looseness, and critically, no loss of performance. The aluminum construction feels solid enough that I don’t foresee any issues arising from minor impacts or stresses.

Maintenance is practically non-existent. A quick wipe-down with a dry cloth is all that’s needed to keep it clean. The TORX screws are standard and don’t strip easily, which is a common frustration with lesser mounting hardware. It’s a set-it-and-forget-it kind of component, which is precisely what you want for a rifle accessory.

Compared to the stock rail that came with my rifle, this Ruger base is a clear upgrade. That original rail, while functional, didn’t offer the flexibility needed for certain shooting scenarios. This 0 MOA Picatinny Alumonum Black Hard Coat Anodized unit addresses that specific limitation perfectly, and frankly, it performs as well as, if not better than, some significantly more expensive options I’ve encountered from other brands.

Breaking Down the Features of Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized

Specifications

The Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized is a one-piece scope base meticulously machined from billet aluminum. It measures 5.25 inches in length, providing ample real estate for most rimfire scope mounting configurations. The finish is a tough black hard anodize, designed for durability and resistance to abrasion.

This base features MIL-STD Picatinny slot-and-rail spacing, ensuring compatibility with a wide range of Picatinny or Weaver scope rings. The critical specification here is its 0 MOA cant, meaning it provides a perfectly level mounting surface. This is ideal for shorter-range shooting or when using scope rings with built-in cant.

The attachment type is screw-on, utilizing the provided (4) TORX mounting screws. The included T-10 wrench means you have everything you need to install it right out of the box. The gun type it’s designed for is a rifle, specifically suited for rimfire platforms where precise zeroing at various distances is important.

Performance & Functionality

The primary job of this scope base is to provide a stable and level platform for mounting an optic. In this regard, the Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized performs exceptionally well. Its 0 MOA designation is key, allowing for maximum downward adjustment on many scopes when shooting at closer targets, preventing the frustrating scenario of bottoming out the turrets.

The strengths of this unit are its simplicity, robust construction, and precise fit. It does exactly what it’s supposed to without any unnecessary complexity. The black hard coat anodized finish also contributes positively, offering a non-reflective surface that won’t detract from your sight picture.

A potential weakness, though minor, is that it is a fixed 0 MOA base. While this is its primary selling point for specific applications, it means it’s not ideal for long-range shooting where a canted base might be necessary to achieve sufficient elevation adjustment. However, for its intended use with rimfire rifles at typical ranges, its performance is superb.

Considering its price point, this scope base not only meets but exceeds expectations. It offers the functionality and durability often found in much more expensive aftermarket components. It’s a no-nonsense, effective solution for its intended purpose.

Design & Ergonomics

The design of the Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized is elegantly functional. The one-piece design is inherently strong and reduces potential points of failure. Machined from solid billet aluminum, it feels robust and substantial.

Ergonomically, it’s designed for function over form. The Picatinny slots are precisely milled, ensuring a secure grip for scope rings. The black hard coat anodized finish provides a good tactile feel and a non-slip surface, though the base itself is not handled extensively during shooting.

Practical design details include the well-defined Picatinny slots and the clean lines of the aluminum construction. There are no sharp edges, and the finish is consistent across the entire unit. The inclusion of TORX mounting screws is a practical choice for secure fastening.

Durability & Maintenance

Given its construction from billet aluminum and the black hard coat anodized finish, this scope base is built for long-term durability. Under normal use for a rimfire rifle, I expect it to last the lifetime of the firearm. The material is resistant to corrosion, and the anodizing protects against scratches and wear.

Maintenance is minimal. A simple wipe-down with a soft cloth to remove dust or debris is sufficient. The TORX screws are designed to be tightened securely, and as long as they are not over-tightened, they will provide a reliable attachment point without stripping.

The primary potential failure point would be extreme impacts or overtightening of the mounting screws, which could damage the aluminum. However, within the scope of typical shooting activities, it’s a highly reliable component.

The Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized comes with a complete mounting kit. This includes (4) TORX mounting screws and a T-10 wrench. These are essential accessories that allow for immediate installation upon receipt.

Beyond the included hardware, customization options are limited to the choice of scope rings that will attach to the Picatinny rail. The MIL-STD Picatinny slot-and-rail spacing ensures compatibility with a vast array of rings from numerous manufacturers, including both Picatinny and Weaver styles.

While the base itself isn’t customizable, its compatibility with standard mounting solutions makes it a flexible choice. You can select the rings that best suit your scope and shooting preferences without being limited by the base itself.

Pros and Cons of Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized

Who Should Buy Ruger 90673 Precision Rimfire 0 MOA Picatinny Alumonum Black Hard Coat Anodized?

This scope base is ideally suited for rimfire rifle owners who frequently shoot at closer distances, such as 25, 50, or 100 yards.

Individuals who should probably skip this product are those primarily engaged in long-range precision shooting with rimfire rifles. For distances requiring significant elevation adjustment (e.g., 200 yards and beyond), a base with a built-in cant (like 10 or 20 MOA) would be more appropriate. Additionally, if you are mounting a scope on a high-powered centerfire rifle intended for extreme distances, this 0 MOA base would likely be insufficient.

Must-have accessories would simply be the scope rings of your choice. Given the Picatinny interface, you have a wide selection to pick from. I personally prefer medium-height rings for most rimfire scopes to ensure adequate clearance from the barrel.
