NcSTAR AK Keymod Mount Receiver Cover Review

Let Me Walk You Through the NcSTAR AK Keymod Mount Receiver Cover

The NcSTAR AK Keymod Mount Receiver Cover promises to modernize the classic AK platform by providing a stable and versatile mounting solution for optics and accessories. Manufactured by NcSTAR, this receiver cover aims to bridge the gap between traditional AK aesthetics and modern tactical requirements. It boasts Keymod slots on three sides, a pre-drilled top for NcSTAR micro dots, and a claimed drop-in fit for AKM pattern rifles.

I’ve always struggled with mounting optics on my AK pattern rifles. Side rails work, but they often add bulk and throw off the balance. I was looking for a lower-profile, more streamlined solution.

The initial unboxing revealed a surprisingly lightweight receiver cover, primarily constructed of aluminum with some steel components. The black finish appeared even, though the overall build quality felt somewhat…budget-conscious. Compared to a Midwest Industries railed receiver cover I’ve used in the past, the NcSTAR felt noticeably less robust.

My first impression was cautiously optimistic. The concept seemed promising, but the actual execution left me wondering about long-term durability and fitment issues given the price of $22.87. I hoped the price would be justified by the product.

Real-World Testing: Putting NcSTAR AK Keymod Mount Receiver Cover to the Test

First Use Experience

I tested the NcSTAR AK Keymod Mount Receiver Cover at an outdoor shooting range during a relatively dry, cool day. My test platform was a WASR-10, a common AKM pattern rifle. Installation proved to be…challenging.

The cover initially refused to seat correctly, requiring considerable force. After about 30 minutes of fiddling and some light filing on the front tabs (as suggested by other online reviews), I finally managed to get it to lock into place. The top Keymod slots provided a secure mount for a red dot sight, although the claimed “co-witness” with iron sights using a NcSTAR micro dot didn’t quite materialize, requiring a cheek riser for comfortable use.

Extended Use & Reliability

After several range sessions and approximately 500 rounds fired, the NcSTAR AK Keymod Mount Receiver Cover has shown some signs of wear. The finish around the ejection port has started to chip, and the screws securing the rear of the cover required tightening after each use to mitigate any wobble. While the Keymod sections held accessories securely, the overall stability of the cover remained questionable, especially during rapid fire.

Cleaning was straightforward, though I noticed some minor rust forming on the steel components despite diligent oiling. It’s clear that the NcSTAR AK Keymod Mount Receiver Cover, while functional, doesn’t inspire the same confidence as more robust (and significantly more expensive) alternatives. It doesn’t outperform, or disappoint.

Breaking Down the Features of NcSTAR AK Keymod Mount Receiver Cover

Specifications

• Material: The NcSTAR AK Keymod Mount Receiver Cover utilizes a combination of aluminum (for the rail sections) and steel (for the receiver cover itself). This blend attempts to balance weight and durability, but the quality of the materials impacts the overall sturdiness.
• Length: The cover measures 9.5 inches in length, providing ample space for mounting various accessories. This length, however, can interfere with some aftermarket recoil spring guide rods.
• Weight: Weighing in at 7.3 ounces, the receiver cover adds minimal weight to the rifle. This is a positive aspect, as it doesn’t significantly alter the rifle’s balance.
• Mounting System: The Keymod slots on the top and sides offer versatile mounting options for optics, lights, and other accessories. However, the cover’s stability can affect the accuracy of mounted optics, and the tolerance of the Keymod slots may vary.
• Compatibility: It is designed to fit AKM pattern rifles with stamped receivers chambered in 7.62X39, 5.45X39, and .223. Fitment issues with specific rifles, such as Yugo or Zastava AKs, have been reported.
• Included Accessories: The package includes three front tabs and two rear screws for securing the receiver cover. The quality of these screws is questionable, and some users may need to replace them with more durable alternatives.

Performance & Functionality

The NcSTAR AK Keymod Mount Receiver Cover aims to provide a stable platform for mounting optics and accessories on AK pattern rifles. In practice, its performance is inconsistent. While the Keymod slots offer versatility, the overall stability of the cover can be a limiting factor.

The pre-drilled holes for NcSTAR micro dots are a nice touch, but the lack of true co-witness with iron sights diminishes their utility. The fitment issues reported by other users suggest a lack of precise manufacturing tolerances.

Design & Ergonomics

The design of the NcSTAR AK Keymod Mount Receiver Cover is generally functional, but the overall build quality leaves something to be desired. The aluminum rail sections feel adequate, but the steel receiver cover feels thin and flimsy. This impacts the long-term durability of the product.

The lightweight design is a plus, but the loose fit and potential for wobble detract from the overall user experience. A more robust locking mechanism would significantly improve its ergonomics.

Durability & Maintenance

The long-term durability of the NcSTAR AK Keymod Mount Receiver Cover is a major concern. The finish is prone to chipping, and the steel components are susceptible to rust. Regular maintenance, including cleaning and oiling, is essential to prevent corrosion.

The screws securing the cover may require frequent tightening or replacement. A more robust construction and higher-quality materials would significantly extend its lifespan.

Accessories and Customization Options

The NcSTAR AK Keymod Mount Receiver Cover is designed to be compatible with a wide range of Keymod accessories, including optics, lights, and vertical grips. The pre-drilled holes allow for direct mounting of NcSTAR micro dots. However, compatibility with other brands of optics may vary.

Due to the cover’s non-standard dimensions, traditional AK dust cover replacements are typically not compatible. Customization options are, therefore, limited to Keymod accessories that can be directly attached to the rail sections.

Pros and Cons of NcSTAR AK Keymod Mount Receiver Cover

Who Should Buy NcSTAR AK Keymod Mount Receiver Cover?

The NcSTAR AK Keymod Mount Receiver Cover is perfect for budget-minded AK owners who are looking for an inexpensive way to mount optics and accessories. It is also suitable for those who enjoy tinkering and are comfortable with minor modifications to achieve a proper fit.

Those who demand high levels of accuracy and reliability should skip this product. Those who own Yugo or Zastava pattern AKs might also want to steer clear due to potential fitment issues.

Must-have accessories or modifications include: a quality red dot sight, thread locker for the mounting screws, and potentially a replacement recoil spring guide rod if the stock one interferes with the receiver cover.

Conclusion on NcSTAR AK Keymod Mount Receiver Cover

The NcSTAR AK Keymod Mount Receiver Cover is a mixed bag. Its low price is certainly appealing, and the Keymod system offers a degree of versatility that traditional AKs lack. However, the inconsistent fitment, questionable durability, and lack of true co-witness with iron sights make it difficult to wholeheartedly recommend.

The value proposition is debatable. While the price is low, the potential need for modification and the risk of early failure diminish its overall value.

I would only cautiously recommend the NcSTAR AK Keymod Mount Receiver Cover to AK owners who are on a very tight budget and are willing to accept its limitations. For those who demand higher quality and reliability, it’s worth investing in a more robust and well-engineered mounting solution. Do you want to try it?
