Rock River Arms Marksman 6-Pos Stock Kit Review

First Impressions of Rock River Arms Marksman 6-Pos Stock Kit

The Rock River Arms Marksman 6-Pos Stock Kit promises enhanced ergonomics and adjustability for the AR-15 platform, and it’s a promise that piqued my interest. Rock River Arms has a solid reputation in the AR world, and this kit appeared to be a well-rounded offering, including not just the stock itself but also the necessary components for installation. I was particularly drawn to the adjustable cheek piece, a feature I’ve found greatly improves shooting comfort and consistency, especially when using optics.

I’ve been chasing the “perfect” AR setup for years, always tweaking and refining for optimal comfort and performance. My biggest challenge has been achieving a consistent cheek weld with various optics, a frustration that led me to seek out a stock with an adjustable cheek piece. I needed a stock that offered a solid, stable platform with the versatility to adapt to different shooting positions and gear configurations.

Upon unboxing, the Rock River Arms Marksman 6-Pos Stock Kit immediately impressed me with its robust construction and thoughtful design. The polymer felt dense and durable, and the tan color was consistent and aesthetically pleasing. The included buffer tube, buffer, spring, and other components appeared to be of high quality. The adjustable cheek piece moved smoothly and locked securely into place.

Compared to a basic M4 stock or even some of the more budget-friendly adjustable stocks I’ve used, the Rock River Arms offering stood out for its enhanced adjustability and perceived sturdiness. I considered options from Magpul and BCM, but the Rock River Arms kit offered a more complete package at a comparable price, including the buffer assembly, which sealed the deal for me. The adjustability of the cheek piece was also a deciding factor.

My initial impression was one of excitement. The Rock River Arms Marksman 6-Pos Stock Kit felt like a significant upgrade over my existing stock, and I was eager to install it and put it through its paces. I was hopeful that it would solve my cheek weld issues and provide a more comfortable and stable shooting platform.

Real-World Testing: Putting Rock River Arms Marksman 6-Pos Stock Kit to the Test

First Use Experience

My first test of the Rock River Arms Marksman 6-Pos Stock Kit was at my local shooting range, an outdoor facility with a variety of targets at distances ranging from 25 to 300 yards.

The weather was mild and sunny, ideal conditions for testing.

The immediate improvement in shooting comfort was noticeable. The adjustable cheek piece allowed me to achieve a perfect cheek weld with each of my optics, resulting in improved accuracy and faster target acquisition. The 6-position adjustability of the stock itself also allowed me to fine-tune the length of pull for optimal comfort. No issues arose during this first outing, it was a noticeable upgrade.

I’ve seen no significant signs of wear and tear, even after repeated adjustments and exposure to the elements. The finish has held up well, and the stock continues to function as smoothly as it did on day one. Cleaning is straightforward; a quick wipe down with a damp cloth is usually all that’s needed.
