Evolution Gun Works EVOLVED AR Lower Receiver Parts Kit Review

First Impressions of Evolution Gun Works EVOLVED AR Lower Receiver Parts Kit

The Evolution Gun Works EVOLVED AR Lower Receiver Parts Kit promises enhanced quality and corrosion resistance for your AR build. Evolution Gun Works (EGW) aims to provide a premium alternative to standard, often overlooked lower parts kits, focusing on precision machining and durable coatings.

As a seasoned gun builder, I’ve grown weary of settling for subpar components in the lower receiver. My quest was for a parts kit that matched the quality of high-end triggers and optics, ensuring a reliable and long-lasting foundation for my AR.

Upon unboxing, the parts exuded a sense of quality, with a uniform black QPQ coating and a reassuring heft. The machined components looked precise, a stark contrast to some of the MIM (Metal Injection Molded) parts found in typical kits. My initial impression was one of cautious optimism. This kit felt like it could be a game-changer. I’ve been piecing together ARs for over a decade, and the difference between a smooth, reliable build and a frustrating one often comes down to the details.

I’ve used lower parts kits from companies like CMMG and Aero Precision in the past. While those kits are functional and offer a good value, the EGW kit appeared to offer a superior level of machining and finish. It seemed EGW focused on creating a truly premium product in a market often dominated by budget-friendly options.

My first thought was, “Finally, a lower parts kit that doesn’t feel like an afterthought!”

Real-World Testing: Putting Evolution Gun Works EVOLVED AR Lower Receiver Parts Kit to the Test

First Use Experience

I installed the Evolution Gun Works EVOLVED AR Lower Receiver Parts Kit on a new AR build intended for range use and potential home defense. I completed the assembly in my workshop, carefully following standard procedures and documenting any challenges or areas of concern.

The kit performed admirably during initial testing at an outdoor range. I fired approximately 500 rounds of .223 ammunition through the rifle in dry conditions, experiencing no malfunctions related to the lower receiver parts. The magazine release and bolt catch functioned flawlessly. The takedown pins were snug but not overly tight.

One minor surprise was how smooth the magazine release felt. It required minimal effort to engage and disengage, a testament to the precise machining.

Extended Use & Reliability

After several range trips spanning a few months and exceeding 2,000 rounds fired, the Evolution Gun Works EVOLVED AR Lower Receiver Parts Kit continued to perform reliably. The QPQ coating showed no signs of wear, even on high-friction parts like the bolt catch.

Maintenance was straightforward. Standard cleaning procedures were sufficient to keep the parts in optimal condition. The corrosion-resistant coating made removing carbon fouling easier than with some of my previous builds.

The EGW kit significantly outperformed a previous budget kit I had used, which developed rust spots on the bolt catch and exhibited inconsistent magazine release functionality.

Breaking Down the Features of Evolution Gun Works EVOLVED AR Lower Receiver Parts Kit

Specifications

The Evolution Gun Works EVOLVED AR Lower Receiver Parts Kit includes essential components for completing an AR-15 lower receiver. Key specifications include:

• Material: Critical components (magazine catch, bolt catch, takedown pins, etc.) are precision machined from 4140 tool steel barstock or 7075 T6 aluminum. These materials were selected for strength and durability.
• Finish: Parts are finished with a QPQ (Quench Polish Quench) coating for enhanced corrosion resistance. This coating is known for its hardness and ability to withstand wear.
• Springs: Springs are made from stainless steel to prevent rusting. This is a critical feature for maintaining long-term reliability.
• Exclusions: The kit does not include a fire control group (trigger, hammer, disconnector), safety selector, or pistol grip. This allows users to select these components based on personal preference.
• Manufacturing: The kit’s components are made in specialized factories. The precision machining and high-quality materials contribute to its overall reliability.

These specifications are essential because they directly impact the reliability and longevity of the AR-15 platform. High-quality materials and coatings ensure smooth operation and prevent premature wear.

Performance & Functionality

The Evolution Gun Works EVOLVED AR Lower Receiver Parts Kit performs its job exceptionally well. The magazine release is smooth and consistent, providing positive magazine engagement. The bolt catch functions reliably, locking the bolt back on an empty magazine every time. Takedown pins are properly sized for easy removal and installation while maintaining a secure fit.

The kit’s strength lies in its consistent performance and durability. The only area for potential improvement is the inclusion of a high-quality trigger group as an option. I expect the parts to last the lifetime of the rifle.

It exceeded my expectations by delivering a level of refinement and reliability not typically found in standard lower parts kits.
