KNS Precision Turned Lower Parts Kit Review

Let’s Talk About KNS Precision Turned Lower Parts Kit

The KNS Precision Turned Lower Parts Kit offers a budget-friendly solution for completing or upgrading the lower receiver of your AR-15. KNS Precision, known for its innovative and robust firearm components, provides a basic but functional set of essential parts. I decided to try this kit as a cost-effective way to finish a dedicated .22LR build and ensure reliable operation.

I had been piecing together a budget-friendly AR-15 lower to use with a dedicated .22LR upper. I didn’t want to spend a fortune on high-end, match-grade components for a .22 build, but I also didn’t want to compromise on reliability. The KNS Precision Turned Lower Parts Kit seemed like a good balance between cost and quality.

Upon receiving the kit, my initial thoughts were positive. The parts appeared well-machined, and the finish was consistent. There was no flashy packaging, just the essential components neatly organized in a small bag, signaling a focus on function over presentation.

Compared to complete lower parts kits from CMC Triggers or Timney, the KNS Precision kit is significantly more basic. Those kits come with enhanced triggers and other upgraded components. However, those kits also come with a significantly higher price tag, making the KNS Precision kit a perfect alternative for a budget build like mine.

My first impression was one of cautious optimism. The kit seemed well-made for the price, and I was eager to see how it performed in my build. I anticipated a straightforward installation and hoped for reliable function, even if it didn’t offer the enhanced feel of more expensive options.

Real-World Testing: Putting KNS Precision Turned Lower Parts Kit to the Test

First Use Experience

I tested the KNS Precision Turned Lower Parts Kit on my dedicated .22LR AR-15 build at my local outdoor shooting range. The range offered a variety of distances, allowing me to assess the functionality and reliability of the lower parts kit under different shooting conditions. The weather was dry and sunny, providing ideal conditions for testing.

The kit performed adequately in the dry conditions. The pins went in smoothly during the initial build, and all functions worked as expected. There were no immediately obvious issues.

I did not need any time to get used to it, given the familiarity with the AR-15 platform. The trigger pull was standard for an AR-15 with mil-spec components.

After the first range session, I did notice some slight burrs on the hammer pin. The burrs did not immediately impact function. I made a mental note to keep an eye on it for future wear.

Extended Use & Reliability

After several months of use and approximately 500 rounds through the .22LR upper, the KNS Precision Turned Lower Parts Kit has held up surprisingly well, considering its budget-friendly price point. There are some signs of wear on the finish of the hammer and trigger, but nothing unexpected for a mil-spec type kit. The pins remain securely in place.

The durability has been acceptable. The pins are steel and exhibit normal wear from use. No parts have broken or malfunctioned.

The maintenance has been straightforward. Regular cleaning and lubrication are essential, just like any other AR-15 lower parts kit. I use CLP (Clean, Lubricate, Protect) to keep the components functioning smoothly.

Compared to previous experiences with higher-end lower parts kits, the KNS Precision kit performs adequately but lacks the enhanced feel and refined trigger pull of premium options. It gets the job done for a budget build. It does not offer the crispness or adjustability of higher-end triggers.

Breaking Down the Features of KNS Precision Turned Lower Parts Kit

Specifications

The KNS Precision Turned Lower Parts Kit includes the following components:

• Bolt Catch Detent: A small but crucial part, it retains the bolt catch in the receiver. It allows the bolt to be locked back after the last round is fired.
• Buffer Detent: This part secures the buffer and buffer spring within the buffer tube. It prevents the buffer from launching out of the receiver when the upper receiver is removed.
• Two Pivot/Take Down Detents: These detents, along with their springs, secure the pivot and takedown pins. They ensure the upper and lower receivers remain connected during operation.
• Standard Take Down Pin: The rear pin that connects the upper and lower receivers. It’s a standard component for AR-15 assembly.
• Standard Pivot Pin: The front pin that connects the upper and lower receivers. Similar to the takedown pin, it is a standard AR-15 part.
• Standard Hammer Pin: This pin secures the hammer in the lower receiver. It allows the hammer to pivot and strike the firing pin.
• Standard Trigger Pin: This pin secures the trigger in the lower receiver. It allows the trigger to pivot and release the hammer.
• Safety Detent: The safety detent, along with its spring, engages with the safety selector. It allows the user to switch between safe and fire modes.

These specifications are important because they represent the essential components needed to complete the lower receiver. The quality of these parts impacts the overall reliability and function of the rifle. If these parts are out of spec, the rifle may not function properly.
