Guntec USA AR-15 A2 Buffer Spring Set Review

Let’s Dive into Guntec USA AR-15 A2 Buffer Spring Set

The AR-15 platform is renowned for its modularity, and at the heart of its cycling action lies the buffer system. The Guntec USA AR-15 A2 Buffer Spring Set promises to deliver reliable performance for rifle-length AR-15 builds. Let’s dig into whether it lives up to that promise, based on my extensive experience with AR platform rifles.

I was rebuilding a classic M16 clone when I realized I needed a proper A2 rifle-length buffer spring. I was aiming for authenticity and reliability, and I didn’t want to cut corners with a cheap or unreliable spring. I wanted a spring that would smoothly cycle the action and withstand long-term use, without introducing excessive “twang” or cycling issues.

Upon receiving the Guntec USA AR-15 A2 Buffer Spring Set, my initial impression was favorable. The spring felt robust, and the finish was clean, indicative of decent manufacturing. Its weight felt comparable to other mil-spec springs I’ve used in the past, signaling it was likely manufactured to correct specifications.

Compared to more expensive, “premium” buffer springs (like those from JP Enterprises), the Guntec USA offering lacks the polished finish and claims of reduced friction. However, those premium options come at a significantly higher price point. I also considered a standard Colt A2 spring, but the Guntec USA set was readily available and competitively priced.

My initial excitement was tempered with a healthy dose of skepticism, as budget-friendly AR parts can sometimes be a gamble. My hope was that this spring would provide reliable performance without breaking the bank.

Real-World Testing: Putting Guntec USA AR-15 A2 Buffer Spring Set to the Test

First Use Experience

My primary testing ground for the Guntec USA AR-15 A2 Buffer Spring Set was at my local outdoor shooting range. I installed it in my M16 clone build and ran several hundred rounds through it, mixing .223 Remington and 5.56 NATO ammunition. The rifle was tested from prone, standing, and benchrest positions.

The Guntec USA spring performed flawlessly throughout the initial testing session, even when the rifle became noticeably dirty after extended firing. I didn’t experience any failures to feed, failures to eject, or other cycling issues that could be attributed to the buffer spring. The rifle cycled smoothly and consistently, indicating a proper balance between gas pressure and buffer spring resistance.

The spring’s resistance felt appropriate for a rifle-length system, neither too stiff nor too weak. There was a slight “twang” during cycling, which is common with standard mil-spec springs, but it wasn’t excessive or distracting. The installation process was also straightforward, dropping in without any fitment issues.

Extended Use & Reliability

After several months of regular use, the Guntec USA AR-15 A2 Buffer Spring Set continues to perform reliably. I’ve put approximately 1000 rounds through the rifle since installing the spring. The spring has been subjected to various weather conditions.

I have noticed minimal wear and tear on the spring itself, with no signs of significant corrosion or deformation. The rifle continues to cycle smoothly and consistently, even when firing different types of ammunition or after extended periods without cleaning. The spring still exhibits a slight “twang” during cycling, but the noise level has remained consistent.

Cleaning and maintaining the Guntec USA spring is easy; simply wipe it down with a lightly oiled cloth during routine rifle maintenance. Compared to some of the higher-end springs I’ve used in the past, the Guntec USA spring hasn’t shown any significant advantage in terms of reduced recoil or improved cycling smoothness. However, it also hasn’t exhibited any reliability issues or performance deficiencies, proving it to be a dependable option.

Breaking Down the Features of Guntec USA AR-15 A2 Buffer Spring Set

Specifications

• The Guntec USA AR-15 A2 Buffer Spring Set is designed for use in AR-15 rifles utilizing an A2 rifle-length buffer tube system. The spring is chambered for .223 caliber (5.56 NATO), making it suitable for standard AR-15 builds.
• The kit includes one mil-spec rifle-length buffer spring. This spring is designed to meet military specifications, ensuring compatibility with most standard A2 buffer systems.
• The spring is constructed from high-quality steel, providing durability and resistance to corrosion. The black finish offers a basic level of protection and blends well with most AR-15 components.

These specifications are crucial for maintaining the proper cycling of the AR-15 rifle. The rifle-length spring, in conjunction with the correct buffer weight, ensures that the bolt carrier group travels the appropriate distance to reliably chamber rounds, extract spent casings, and reset the trigger.

Performance & Functionality

The Guntec USA AR-15 A2 Buffer Spring Set performs its primary function effectively: reliably cycling the action of an AR-15 rifle. It consistently provides the necessary resistance to ensure proper bolt lockup and prevents bolt bounce, contributing to overall accuracy and reliability.

• Its strengths lie in its consistent performance and affordable price point. The spring provides adequate cycling force without being overly stiff, making it suitable for a wide range of ammunition types.
• One potential weakness is the presence of a slight “twang” during cycling, which can be noticeable to some shooters. However, this is a common characteristic of standard mil-spec springs and doesn’t affect functionality.

Overall, the Guntec USA spring meets my expectations for a standard A2 buffer spring. It performs reliably and consistently without any major drawbacks.

• There is no learning curve associated with using this spring. It’s a drop-in replacement for any standard A2 buffer spring, requiring no special tools or modifications.

Durability & Maintenance

The Guntec USA AR-15 A2 Buffer Spring Set appears to be reasonably durable, showing minimal signs of wear and tear after several months of use. The steel construction provides good resistance to corrosion, and the spring retains its original length and shape.

• The spring should last for several thousand rounds with proper maintenance. Regular cleaning and lubrication will help to extend its lifespan and maintain optimal performance.
• The spring is easy to maintain; simply wipe it down with a lightly oiled cloth during routine rifle cleaning. There are no special repair procedures required, as the spring is typically replaced rather than repaired.

The Guntec USA AR-15 A2 Buffer Spring Set is a standalone component and doesn’t come with any additional accessories. However, it’s compatible with a wide range of A2 buffer tubes, buffers, and stocks from various manufacturers.

• Users can customize their buffer system by selecting different buffer weights to fine-tune the rifle’s cycling characteristics. Heavier buffers can help to reduce recoil and improve reliability with certain types of ammunition.
• The spring is also compatible with aftermarket recoil reduction systems that replace the standard buffer and spring with more advanced designs.
