Let’s Talk About LBE Unlimited AR15 Carbine Length Recoil Spring
The LBE Unlimited AR15 Carbine Length Recoil Spring is a seemingly simple component, but it plays a crucial role in the AR-15 platform’s reliable operation. As an experienced armorer, I’ve seen firsthand how a worn or out-of-spec recoil spring can cause cycling issues, failures to feed, and even damage to other components. This LBE Unlimited offering promises to restore or maintain proper function in carbine-length AR-15s, and I was keen to see if it lives up to expectations, especially considering its budget-friendly price point.
My primary reason for exploring this particular spring was to address inconsistent cycling in one of my older AR builds. The rifle, a trusty workhorse, had started exhibiting occasional failures to eject, suggesting a weakening recoil spring. Several high-end options were available, but I wanted to test the market to see if a value-priced spring can deliver comparable performance.
Upon unboxing, the LBE Unlimited AR15 Carbine Length Recoil Spring appeared well-made, exhibiting a consistent coil diameter and overall length. The spring steel seemed reasonably robust, although a deeper dive would be required to assess its long-term durability. Compared to a higher-end spring I had on hand, the finish wasn’t quite as refined, but it was perfectly acceptable for a component in this price range.
I chose the LBE Unlimited spring over other budget options because of LBE Unlimited‘s established reputation for providing functional, if not always aesthetically perfect, parts. Some competitors in this price bracket have questionable quality control, making LBE Unlimited a safer bet. Initially, I was cautiously optimistic. I hoped to resolve my cycling issues without breaking the bank.
Real-World Testing: Putting LBE Unlimited AR15 Carbine Length Recoil Spring to the Test
First Use Experience
I first tested the LBE Unlimited AR15 Carbine Length Recoil Spring at my local shooting range, installing it in the aforementioned AR-15 exhibiting cycling issues. The rifle was subjected to a battery of tests, including firing various ammunition types (55-grain FMJ, 62-grain green tips, and 77-grain match ammo) in both dry and slightly dusty conditions. I wanted to see how the spring performed across a range of ammo pressures and environmental conditions.
Immediately after installation, the rifle felt noticeably smoother, with a less “gritty” cycling action. During the initial testing phase, which consisted of approximately 200 rounds, the rifle cycled flawlessly with all ammunition types. No failures to feed, eject, or extract were observed, a significant improvement over its previous performance.
There was a slightly increased “sproing” noise while firing, which is not abnormal in AR platforms, especially with new recoil springs, but it was nothing that detracted from the shooting experience.
Extended Use & Reliability
After several range trips and approximately 1000 rounds fired, the LBE Unlimited AR15 Carbine Length Recoil Spring continues to perform reliably. The rifle continues to cycle smoothly and consistently.
There are no noticeable signs of wear and tear on the spring itself, though, of course, springs are always slowly fatiguing with each compression. The ease of maintenance is identical to any other AR-15 recoil spring; no special cleaning or lubrication procedures are necessary. A simple wipe-down with a lightly oiled cloth is sufficient to prevent corrosion.
Compared to the worn-out spring it replaced, the LBE Unlimited spring represents a significant improvement. While it may not offer the refined feel or extended lifespan of a premium spring, its performance and reliability are perfectly adequate for most shooters. In fact, it outperformed my expectations, given the price point.
Breaking Down the Features of LBE Unlimited AR15 Carbine Length Recoil Spring
Specifications
The LBE Unlimited AR15 Carbine Length Recoil Spring is designed to function in standard AR-15 carbine buffer tubes. It is constructed from spring steel and intended to provide the necessary resistance for proper cycling of the AR-15 bolt carrier group. The spring’s overall length and coil count are engineered to meet Mil-Spec dimensions for carbine-length AR-15s.
These specifications are vital because the recoil spring directly impacts the rifle’s cycling rate and reliability. A spring that is too weak can cause short-stroking, while a spring that is too strong can cause failures to feed. Adhering to Mil-Spec dimensions ensures compatibility with a wide range of AR-15 components and ammunition.
Performance & Functionality
The LBE Unlimited AR15 Carbine Length Recoil Spring performs its primary job admirably: it reliably cycles the AR-15 bolt carrier group. I was able to consistently cycle various ammo types with no malfunctions.
Its greatest strength is its functionality at its price point. There aren’t any noticeable weaknesses in the spring’s operational performance. It met and exceeded my expectations for a budget-friendly recoil spring.
Design & Ergonomics
The spring’s design is simple and functional, adhering to established Mil-Spec dimensions. The spring’s build quality is adequate, though not exceptional. The materials used appear to be durable enough for typical range use and recreational shooting.
The spring’s user-friendliness is inherent in its design. As a drop-in replacement for the original recoil spring, it requires no specialized tools or gunsmithing skills. Installation is straightforward and can be completed in a matter of minutes.
Durability & Maintenance
The spring’s lifespan is difficult to predict precisely, but based on my experience with similar components, it should provide several thousand rounds of reliable service before requiring replacement. Maintenance is minimal, consisting primarily of periodic cleaning and lubrication to prevent corrosion. A solvent and oil combo is fine for cleaning.
Accessories and Customization Options
The LBE Unlimited AR15 Carbine Length Recoil Spring does not come with any additional accessories, nor does it offer any inherent customization options. It is a standard, drop-in replacement part. Its compatibility with other components and brands is ensured by its adherence to Mil-Spec dimensions. This means it will work with a wide range of aftermarket buffer tubes, buffers, and bolt carrier groups.
