Ruger AMER RF HC HI/CMP MODULE Review

The Ruger AMER RF HC HI/CMP MODULE Made a Bold First Impression

The Ruger AMER RF HC HI/CMP MODULE isn’t exactly the kind of tactical gear that gets your adrenaline pumping. It’s a seemingly simple piece of molded polymer, yet it promises a significant improvement to the ergonomics and usability of the Ruger American Rimfire rifle, especially when paired with optics. I first learned about the Ruger AMER RF HC HI/CMP MODULE when I bought a standard Ruger American Rimfire for my son.

His shorter stature made it difficult for him to comfortably and accurately shoot the rifle with its factory stock. The quest to find a solution that would fit him better while using a scope led me to this seemingly humble, yet potentially game-changing, stock module. Unboxing the Ruger AMER RF HC HI/CMP MODULE was less of an “unboxing” and more of a “unpacking.”

The module comes in a simple plastic bag with minimal fanfare. My initial impression was that the polymer felt sturdy and well-molded, without any noticeable imperfections or sharp edges. Compared to aftermarket adjustable stocks designed for AR-15 platforms, the Ruger AMER RF HC HI/CMP MODULE is decidedly low-tech.

However, it appeared far more robust than the factory stock module it was intended to replace. While adjustable stocks offer versatility, they often come with a higher price tag and more complex mechanisms that can fail. I chose the Ruger AMER RF HC HI/CMP MODULE because it promised a simple, reliable, and affordable solution to my son’s length-of-pull and cheek weld issues.

My first impression was a pleasant surprise; it seemed like a well-made, practical upgrade that wouldn’t break the bank. I was eager to see how it would perform in the field and how it would improve my son’s shooting experience.

Real-World Testing: Putting Ruger AMER RF HC HI/CMP MODULE to the Test

First Use Experience

Our first outing with the Ruger AMER RF HC HI/CMP MODULE was at our local outdoor shooting range. The weather was mild, with a slight breeze and clear skies, ideal conditions for sighting in a rimfire rifle. The first thing I noticed was how easily the module swapped out with the original stock.

Installation took less than a minute using only a flat-head screwdriver. The immediate improvement was apparent when my son shouldered the rifle; his eye lined up perfectly with the scope without him having to crane his neck or adjust his stance awkwardly. The improved cheek weld translated directly into tighter groupings on the target.

Even in the calm weather, the enhanced stability afforded by the high comb was noticeable. There were no initial issues or surprises; the module performed exactly as advertised, providing a more comfortable and ergonomic shooting experience.

Extended Use & Reliability

After several weeks of regular use, the Ruger AMER RF HC HI/CMP MODULE continues to impress. It has held up remarkably well, showing no signs of wear and tear despite being subjected to the usual bumps and scrapes associated with range trips. The polymer material seems resistant to scratches and doesn’t discolor easily.

Cleaning is a breeze; a simple wipe down with a damp cloth is usually all that’s needed to remove dirt and grime. Compared to some of the more complex adjustable stocks I’ve used on other rifles, the Ruger AMER RF HC HI/CMP MODULE is refreshingly low-maintenance. My son’s accuracy and confidence have noticeably improved since switching to this module.

His shooting sessions are now more enjoyable and productive. It has exceeded my expectations by providing a simple, durable, and effective solution to the ergonomic challenges he faced with the original stock.

Breaking Down the Features of Ruger AMER RF HC HI/CMP MODULE

Specifications

The Ruger AMER RF HC HI/CMP MODULE is specifically designed as a drop-in replacement for the factory stock module on Ruger American Rimfire rifles. The key specifications include its compatibility with the Ruger American Rimfire rifle, its high comb design optimized for use with optics, and its shorter 12.5-inch length of pull. The module is constructed from a durable molded polymer, ensuring both strength and lightweight handling.

It features a black finish that matches the aesthetics of the Ruger American Rimfire. These specifications are critical because they directly impact the shooter’s comfort, accuracy, and overall shooting experience. The high comb ensures proper eye alignment with optics, while the shorter length of pull is ideal for smaller-framed shooters or those who prefer a more compact rifle configuration.

Performance & Functionality

The Ruger AMER RF HC HI/CMP MODULE performs its primary function exceptionally well: improving the ergonomics of the Ruger American Rimfire for scoped shooting. The high comb raises the shooter’s cheek weld to a level that is naturally aligned with most standard-height scopes. This eliminates the need to strain the neck or use aftermarket cheek risers, which can be bulky and uncomfortable.

The shorter length of pull is also a significant benefit for smaller shooters, allowing them to comfortably reach the trigger and maintain a stable shooting stance. One potential weakness is that the module is not adjustable, so it may not be a perfect fit for every shooter. However, for its intended audience (smaller shooters using optics), it is an outstanding performer.

It has exceeded my expectations by providing a simple and effective solution to common ergonomic issues.

Design & Ergonomics

The Ruger AMER RF HC HI/CMP MODULE boasts a simple yet functional design. The polymer material feels robust and well-made, providing a solid and stable platform for the shooter’s cheek. The module is lightweight, which helps maintain the rifle’s overall balance and maneuverability.

The smooth contours and lack of sharp edges contribute to a comfortable shooting experience. There is virtually no learning curve; the module is a direct replacement for the factory stock and requires no special tools or skills to install. The ergonomic benefits are immediately noticeable, making it a user-friendly upgrade for any Ruger American Rimfire owner.

Durability & Maintenance

Given its simple construction and durable polymer material, the Ruger AMER RF HC HI/CMP MODULE is built to last. It should withstand years of regular use without any significant degradation in performance or appearance. Maintenance is minimal; the module can be easily cleaned with a damp cloth and requires no special lubricants or treatments.

Its robust design and low-maintenance requirements make it an ideal choice for shooters who want a reliable and hassle-free upgrade.

Accessories and Customization Options

The Ruger AMER RF HC HI/CMP MODULE itself doesn’t offer many customization options beyond its basic design. However, it is fully compatible with any accessories that are designed to work with the standard Ruger American Rimfire rifle. This includes a wide range of aftermarket scopes, slings, and bipods.

The module’s primary function is to improve the ergonomics of the rifle when using optics, so the most common accessory pairing would be a quality rimfire scope. It’s also worth noting that the Ruger AMER RF HC HI/CMP MODULE is part of the Ruger American Rimfire’s modular stock system, allowing users to further customize the rifle’s fit and feel with different length-of-pull modules and cheek risers, if desired.
