Kaw Valley Precision PCC 6 Position Mil-Spec Kit Review

First Impressions of Kaw Valley Precision PCC 6 Position Mil-Spec Kit

The Kaw Valley Precision PCC 6 Position Mil-Spec Kit aims to provide everything needed to install a Mil-Spec diameter stock onto a pistol caliber carbine (PCC) AR-15 build. Designed for blowback systems chambered in popular pistol calibers like 9mm, .40 S&W, .45 ACP, and 10mm, this kit includes a buffer and spring specifically tuned to manage the increased recoil and potential for damage in these setups. I was immediately intrigued by the promise of taming the sometimes violent recoil of a PCC build and providing a more reliable and enjoyable shooting experience.

My interest in the Kaw Valley Precision PCC 6 Position Mil-Spec Kit stemmed from persistent issues with my 9mm AR-15 build. It suffered from excessive recoil and occasional failures to extract. I was looking for a solution to smooth out the action, reduce felt recoil, and ultimately improve the reliability of my PCC.

Upon unboxing the Kaw Valley Precision PCC 6 Position Mil-Spec Kit, I was impressed by the apparent quality of the components. The buffer felt substantial, and the finish on the receiver extension tube was clean and even. The included spring appeared to be of good quality, exhibiting a consistent wind and a tight coil.

Before settling on the Kaw Valley Precision PCC 6 Position Mil-Spec Kit, I considered alternatives from JP Enterprises and Spike’s Tactical. I ultimately chose the Kaw Valley Precision kit due to its advertised focus on PCC applications and the integrated heavy buffer designed specifically for blowback systems, believing it would offer a more optimized solution for my 9mm AR-15. The price point was also appealing.

My initial impression of the Kaw Valley Precision PCC 6 Position Mil-Spec Kit was cautiously optimistic. The components seemed well-made. I was eager to see if the kit would live up to its claims of improving the performance and reliability of my PCC build.

Real-World Testing: Putting Kaw Valley Precision PCC 6 Position Mil-Spec Kit to the Test

First Use Experience

I first tested the Kaw Valley Precision PCC 6 Position Mil-Spec Kit at my local outdoor shooting range, focusing on drills that involved rapid firing and transitions between targets. The weather was mild and dry, providing ideal conditions for testing. The range offered a variety of distances, allowing me to evaluate the kit’s impact on both close-quarters and longer-range accuracy.

The difference with the Kaw Valley Precision PCC 6 Position Mil-Spec Kit installed was immediately noticeable. Recoil was significantly reduced, and the cycling of the action felt smoother and more controlled. I was able to maintain a tighter grouping during rapid firing drills, and my split times improved.

The installation process was straightforward, and I encountered no major issues. However, after approximately 100 rounds, I noticed that the buffer retaining pin was starting to walk out slightly. This was a minor inconvenience, but it required me to periodically check and re-seat the pin during my range session.

Extended Use & Reliability

After several months of use, the Kaw Valley Precision PCC 6 Position Mil-Spec Kit has generally held up well, but some issues have surfaced. After approximately 500 rounds, I began to notice some wear on the buffer itself. The finish started to show signs of chipping and scratching.

The receiver extension tube has remained in good condition, with no signs of cracking or bending. However, the buffer retaining pin issue has persisted, requiring frequent monitoring and adjustment. This remains the most significant concern regarding the long-term reliability of the kit.

Compared to my previous setup, which consisted of a standard carbine buffer and spring, the Kaw Valley Precision PCC 6 Position Mil-Spec Kit has offered a noticeable improvement in recoil management and cycling smoothness. However, the buffer retaining pin issue is a definite drawback. I wouldn’t call the Kaw Valley Precision PCC 6 Position Mil-Spec Kit a disappointment, but it hasn’t been a complete home run, either.

Breaking Down the Features of Kaw Valley Precision PCC 6 Position Mil-Spec Kit

Specifications

The Kaw Valley Precision PCC 6 Position Mil-Spec Kit includes the following key specifications:

• Receiver Extension Tube Material: Constructed from 7075-T6 Aluminum, providing a balance of strength and weight.
• Buffer Weight: Features a 10oz Tungsten Blowback Buffer. This helps to reduce recoil and improve cycling reliability in blowback PCC systems.
• Positions: Offers 6 adjustable stock positions. This allows for a customizable length-of-pull.
• Compatibility: Designed for Mil-Spec diameter stocks. This provides broad compatibility with various aftermarket stock options.
• Finish: Features an Anodized finish. This enhances durability and corrosion resistance.

These specifications are important for several reasons. The 7075-T6 aluminum receiver extension provides a robust and reliable platform for mounting the stock. The 10oz tungsten buffer is crucial for managing the increased recoil and bolt velocity in blowback PCC systems, contributing to improved reliability and shooter comfort. The 6-position adjustability allows users to fine-tune the length-of-pull to their specific needs, enhancing ergonomics and control.

Performance & Functionality

The Kaw Valley Precision PCC 6 Position Mil-Spec Kit excels at reducing recoil and improving the cycling smoothness of blowback PCC systems. The heavier buffer effectively slows down the bolt carrier group, mitigating the harshness of the recoil impulse. This leads to better control during rapid firing and reduced muzzle climb.

The primary weakness of the kit is the recurring issue with the buffer retaining pin walking out. This suggests a potential design flaw or tolerance issue that needs to be addressed. Despite this issue, the kit generally meets expectations for improving PCC performance, but the pin issue prevents it from exceeding them.

Design & Ergonomics

The Kaw Valley Precision PCC 6 Position Mil-Spec Kit features a straightforward and functional design. The receiver extension tube is well-machined and the anodized finish provides a clean and durable appearance. The weight of the buffer contributes to a more stable and balanced feel, particularly during rapid firing.

The kit is generally user-friendly. Installation is relatively simple for anyone familiar with AR-15 platform assembly. There is minimal learning curve.

Durability & Maintenance

The receiver extension tube appears to be quite durable and should last for a significant amount of time with proper care. The buffer, however, shows signs of wear and tear after only a moderate amount of use, raising concerns about its long-term durability. The Anodized finish of the Kaw Valley Precision PCC 6 Position Mil-Spec Kit should provide adequate protection against corrosion under normal conditions, but users in harsh environments may need to apply additional protectant as needed.

Maintaining the Kaw Valley Precision PCC 6 Position Mil-Spec Kit is relatively simple. Regular cleaning and lubrication of the buffer and receiver extension tube will help to ensure smooth operation. However, the recurring issue with the buffer retaining pin may require more frequent attention and potential replacement.

Accessories and Customization Options

The Kaw Valley Precision PCC 6 Position Mil-Spec Kit does not come with any additional accessories beyond the receiver extension tube, buffer, spring, and buffer retaining pin. It is designed to be compatible with any Mil-Spec diameter stock. This allows users to choose from a wide variety of aftermarket options to suit their individual preferences.

The kit is also compatible with various aftermarket buffer retaining pins, which may offer a more secure fit and address the recurring issue with the stock pin. Users can also experiment with different buffer springs to further fine-tune the cycling characteristics of their PCC.
