Luth-AR Selector / Ejector Spring Review

Let’s Talk About Luth-AR Selector / Ejector Spring

The Luth-AR Selector / Ejector Spring is a seemingly insignificant part, yet utterly crucial to the reliable function of any AR-15. Without it, you’re looking at a rifle that won’t reliably eject spent casings or allow you to confidently switch between firing modes. It’s that small detail that can be the difference between a successful day at the range and a frustrating experience.

What brought me to examine this seemingly humble spring was a recent AR build project. I was meticulous in sourcing quality components, yet I realized the crucial springs often get overlooked in the excitement of selecting barrels and optics. I needed a reliable spring that I could trust to function flawlessly, ensuring smooth operation of both the selector and ejector mechanisms.

Unboxing the Luth-AR Selector / Ejector Spring (well, unwrapping the small plastic bag it arrived in) revealed a simple, silver-colored spring. My initial impression was positive; it looked clean, well-formed, and ready to work. The spring had a satisfying resilience to it, promising adequate tension without being overly stiff.

Compared to similar springs from other manufacturers, the Luth-AR offering stood out due to Luth-AR’s reputation for quality AR components. I’ve used Luth-AR products in the past and have always been impressed with their consistency. Other options felt either too flimsy or overly rigid, leading me to choose the Luth-AR spring for its balanced feel and trusted name.

My first impression was one of quiet confidence. It’s not a flashy item, but knowing that this small part comes from a reputable manufacturer instills a sense of security. I was eager to get it installed and see how it performed in the rifle.

Real-World Testing: Putting Luth-AR Selector / Ejector Spring to the Test

First Use Experience

I tested the Luth-AR Selector / Ejector Spring at my local outdoor shooting range, where I typically run drills with my AR-15. The weather was typical for that time of year, dry and dusty. I fired several hundred rounds through the rifle, intentionally varying the firing rate to stress the ejector system.

The Luth-AR Selector / Ejector Spring performed flawlessly. Ejection was consistent and strong, sending spent casings flying a good distance away from the rifle. Switching between safe, semi-automatic, and (hypothetically, in a legal setting) full-automatic modes was crisp and positive.

Installation was simple and straightforward. The spring fit perfectly into its designated slots without requiring any excessive force or modification. I was particularly pleased with the selector’s positive engagement, giving me confidence in its functionality.

Extended Use & Reliability

After several months of regular use, the Luth-AR Selector / Ejector Spring continues to perform admirably. There are no signs of wear or fatigue. The ejector still throws casings with authority and the selector remains positive and crisp.

Durability appears to be excellent. The spring shows no signs of corrosion or deformation, despite being exposed to various cleaning solvents and lubrication. It continues to maintain its original tension and resilience.

Maintenance is essentially nonexistent; a quick wipe down during routine cleaning is all that’s needed. Compared to some of the cheaper springs I’ve used in the past, the Luth-AR Selector / Ejector Spring is a significant upgrade in terms of reliability and longevity. It has exceeded my expectations.

Breaking Down the Features of Luth-AR Selector / Ejector Spring

Specifications

The Luth-AR Selector / Ejector Spring is designed as a direct replacement for standard AR-15 selector and ejector springs. It’s manufactured by Luth-AR, a known name in the AR-15 parts market. The spring is finished in a simple, silver color.

• Shipping Weight: 0.25 lbs. This is mostly due to packaging.
• Shipping Dimensions: 1 x 1 x 1 in. A very small part!

These specifications, while minimal, are important because they ensure compatibility with standard AR-15 lower receivers. The proper spring rate is crucial for reliable ejection and selector function. Too weak, and the ejector won’t throw casings far enough. Too strong, and the selector could be difficult to manipulate.

Performance & Functionality

The Luth-AR Selector / Ejector Spring performs its job perfectly. It provides the necessary tension for consistent ejection of spent casings and smooth operation of the fire selector. I experienced no malfunctions related to either the ejector or selector during my testing.

The strength of the spring is its consistent and reliable performance. The only potential downside is that, like any spring, it will eventually wear out over time, requiring replacement. However, given the quality of the Luth-AR spring, I expect a long service life.

It meets and exceeds my expectations for a basic AR-15 spring. It is inexpensive, reliable, and ensures smooth operation of critical rifle functions.

Design & Ergonomics

The design is simple and functional. The spring is made from quality steel and is precisely coiled to provide the correct amount of tension. The weight is negligible, having no impact on the overall balance of the rifle.

It’s a drop-in replacement, requiring no special tools or skills to install. The learning curve is virtually nonexistent.

Durability & Maintenance

Given the quality of the materials and construction, the Luth-AR Selector / Ejector Spring should last for thousands of rounds. Regular cleaning and lubrication of the AR-15 will further extend its lifespan. Replacement is simple, should it eventually be needed.

Maintenance is minimal. Simply inspect the spring for any signs of damage or deformation during routine cleaning.

Accessories and Customization Options

There are no specific accessories or customization options for a selector/ejector spring. It is a standard, functional component. The most important aspect is ensuring that the spring is compatible with your AR-15 lower receiver and fire control group. This spring is designed to work with standard AR-15 components.
