Let’s Dive into CMMG, Inc FNH P90 Style Flash Hider
The CMMG, Inc FNH P90 Style Flash Hider is a muzzle device designed to mitigate muzzle flash and reduce perceived noise, specifically tailored to mimic the iconic appearance of the FN P90 submachine gun. Manufactured by CMMG, a reputable name in AR-15 components and firearms, this flash hider aims to provide both aesthetic appeal and functional benefits for owners of PS90 rifles or those building custom 5.7x28mm platforms. This flash hider instantly evokes a sense of tactical prowess.
I was driven to explore this product while completing a PS90 SBR (Short Barreled Rifle) build, wanting to capture the essence of the original P90. A standard flash hider just wouldn’t cut it; I needed the authentic look.
Out of the box, the CMMG flash hider felt solid and well-machined, finished in a durable black coating. The weight felt appropriate, suggesting quality materials.
Alternatives like the B&T flash hider and some lesser-known brands existed, but I chose the CMMG offering because of CMMG’s reputation for quality and the generally positive reviews, despite some mentioning potential alignment issues. I also noted the price point was attractive compared to B&T.
My initial impression was one of excitement tempered with cautious optimism. The look was exactly what I wanted, but the reported suppressor alignment concerns lingered in the back of my mind.
Real-World Testing: Putting CMMG, Inc FNH P90 Style Flash Hider to the Test
First Use Experience
I tested the CMMG, Inc FNH P90 Style Flash Hider at my local indoor shooting range, primarily focusing on its flash suppression capabilities and overall aesthetics on my newly built PS90 SBR. The range offered a controlled environment to evaluate the flash hider’s performance.
While I didn’t have a high-speed camera to precisely measure flash reduction, it was subjectively noticeable compared to shooting without a flash hider. The reduction in perceived muzzle blast was a welcome change, especially in the confines of the indoor range. Installation was straightforward, threading onto the 10.4″ barrel with relative ease.
The first range session revealed a slight concern – the previously mentioned potential for misalignment when using a suppressor. Although I didn’t experience baffle strikes during the initial test, I carefully monitored the alignment and noticed it wasn’t perfectly concentric.
Extended Use & Reliability
After several months of regular use, the CMMG, Inc FNH P90 Style Flash Hider has held up reasonably well. The black finish shows minor signs of wear around the edges, but overall, it remains in good condition.
The flash hider requires minimal maintenance; a quick wipe down with a cloth after each range session is usually sufficient. I’ve noticed no degradation in performance regarding flash suppression.
Compared to flash hiders I’ve used on AR-15 platforms, the CMMG P90 style flash hider presents a unique challenge due to its specific design requirements for the PS90. While it delivers on the aesthetic front, the potential for suppressor alignment issues is a significant drawback compared to some more universal designs. It did not outperform, it was different.
Breaking Down the Features of CMMG, Inc FNH P90 Style Flash Hider
Specifications
Caliber: 5.7x28mm. This is specifically designed for the 5.7x28mm cartridge used in the FN P90 and PS90 platforms.
Threads per Inch: M12x1LH (Left-Hand). This non-standard thread pitch is crucial for compatibility with the PS90 barrel.
Gun Model: FN P90. This flash hider is designed to mimic the original P90 flash hider for a clone-correct appearance.
Condition: New. The product arrives in new condition, ready for installation.
Manufacturer: CMMG. This CMMG flash hider has a good reputation for quality AR-15 components and firearms.
These specifications are paramount for PS90 owners seeking to either restore their SBR to its original configuration or complete a clone build. The M12x1LH threading is especially critical, as it differentiates this flash hider from those designed for AR-15s and other platforms.
Performance & Functionality
The CMMG, Inc FNH P90 Style Flash Hider performs adequately in reducing muzzle flash, especially in low-light conditions. The design helps to disperse gases, mitigating the bright flash that can momentarily impair vision.
A significant strength lies in its aesthetic contribution, perfectly capturing the iconic look of the P90. The primary weakness is the potential for suppressor alignment issues, as the slanted end may not provide a perfectly flush surface for suppressor attachment, as reported by some users.
For those seeking the authentic P90 look, it exceeds expectations. However, for those prioritizing optimal suppressor performance, it falls slightly short due to the alignment concerns.
Design & Ergonomics
The build quality is generally good, with durable materials and a solid black finish. The weight is appropriate for its size and doesn’t significantly alter the balance of the rifle.
Installation is simple, provided you’re familiar with firearm components and have the necessary tools. The left-hand threading is a key consideration during installation.
Durability & Maintenance
The flash hider appears to be constructed from durable steel, capable of withstanding regular use. Minimal maintenance is required, primarily involving cleaning to remove carbon buildup.
Given the straightforward design and robust materials, it should last for a considerable time with proper care. It is not designed to be repaired, but rather replaced if damaged.
Accessories and Customization Options
The CMMG, Inc FNH P90 Style Flash Hider doesn’t come with any additional accessories. Customization options are limited, as its primary purpose is to replicate the look of the original P90 flash hider.
Its compatibility with suppressors is a key consideration, but, as mentioned, some users have reported alignment issues. Therefore, careful selection of a compatible suppressor and potentially shimming or machining the flash hider may be necessary.
