First Impressions of Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover
The AR-10/LR-308 platform represents a significant step up in power and range from the ubiquitous AR-15. Consequently, every component matters, even seemingly minor ones like the ejection port dust cover. Tiger Rock offers a complete assembly with a 2A engraving, promising both functionality and a touch of personal expression.
I was building an AR-10 for long-range target shooting, and the ejection port cover was the last piece of the puzzle. I needed a reliable cover to protect the internals from dust and debris. I also wanted something that added a bit of visual flair to the build.
Upon receiving the Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover, I immediately noticed the simple, no-frills packaging. The cover itself felt lightweight but solid, and the engraving was crisp and clean. The black finish appeared even and well-applied.
I considered other options, including covers from Magpul and Strike Industries, known for their enhanced features and durability. Ultimately, I chose the Tiger Rock cover due to its combination of affordability, the patriotic 2A engraving, and the promise of a complete assembly, simplifying the installation process. My initial reaction was cautiously optimistic – hoping the low price didn’t translate to low quality.
Real-World Testing: Putting Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover to the Test
First Use Experience
My first test of the Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover occurred during a range day in relatively mild conditions. I installed the cover on my AR-10 and ran approximately 100 rounds through the rifle. The cover initially seemed to function as intended, snapping closed after each firing sequence.
However, even in the dry conditions, I noticed that the cover didn’t always fully seal. After about 50 rounds, the spring-loaded pin showed signs of weakness, failing to consistently keep the door closed. This was a major concern, as the primary purpose of the cover is to prevent debris from entering the action.
Extended Use & Reliability
After several weeks of use, including two more range sessions and a dusty field test, the reliability issues with the Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover worsened. The cover now frequently popped open during firing, and the spring-loaded pin became increasingly unreliable. The finish remained intact with no signs of wear or tear, though.
Cleaning was straightforward since it is a simple part. It only required a quick wipe-down with a cleaning cloth and some solvent. Unfortunately, the functional issues overshadowed the ease of maintenance, making the component unreliable in practical shooting situations. In comparing this to a DPMS factory ejection port cover I have used previously, the difference in spring tension and overall robustness was noticeable, with the DPMS part proving far more reliable.

Performance & Functionality
The primary function of the Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover is to protect the internal components of the rifle from dust, dirt, and debris. Ideally, it should remain closed when the rifle is not in use and reliably snap open upon firing, then automatically close again. Unfortunately, the cover’s performance is inconsistent.
While the cover initially performs its basic function, the weak spring and unreliable pin result in frequent failures to remain closed. This significantly compromises its ability to protect the rifle’s internals. The engraving is aesthetically pleasing and adds a personal touch but doesn’t improve performance.
Design & Ergonomics
The design of the Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover is standard and functional. The lightweight construction doesn’t add noticeable weight to the rifle.
The installation is straightforward, and the cover integrates seamlessly with the AR-10 platform. However, the design doesn’t address the inherent weakness of the spring and pin, which are critical for reliable operation. The 2A engraving is well-executed and aesthetically pleasing but has no impact on ergonomics.
Durability & Maintenance
The finish on the Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover appears to be durable and resistant to scratches and wear. Regular cleaning and lubrication of the pin and spring can help maintain its function.
However, the underlying issue of the weak spring and pin remains a concern. While the cover itself may last a long time, the unreliable spring could require replacement sooner than expected. Proper maintenance is essential to prolonging its lifespan.
Accessories and Customization Options
The Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover is a relatively simple component with limited customization options. It is compatible with most standard AR-10 upper receivers, meaning there are no specific compatibility issues with other aftermarket parts.
Users could potentially replace the spring with a higher-tension alternative or the pin with a more robust version. Other than that, its a simple product. No other accessories are included.

Who Should Buy Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover?
This product is perfect for budget-conscious builders who prioritize aesthetics over absolute reliability. It’s suitable for those who primarily shoot in controlled environments with minimal dust or debris.
Those needing a truly dependable dust cover for harsh conditions or serious tactical applications should skip this product. The unreliability makes it unsuitable for critical situations. A must-have modification would be immediately replacing the included spring with a higher-tension alternative.
Conclusion on Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover
The Tiger Rock AR-10/LR-308 w/ 2A Engraving Complete Assembly Ejection Port Dust Cover offers an attractive combination of affordability and aesthetics. However, the unreliable spring-loaded pin undermines its primary function: protecting the rifle’s internals.
The low price is tempting, but the inconsistent performance makes it a questionable value proposition. While the engraving adds a nice touch, functionality should always come first.
I would not personally recommend this product without reservations. Unless you are prepared to replace the spring or are willing to tolerate its unreliability, there are better options available, even if they cost slightly more. It is a good-looking product, just not particularly good at its job.
