First Impressions of JMac Customs GFHC 14-1LH Face KeyMount KeyMicro
The JMac Customs GFHC 14-1LH Face KeyMount KeyMicro is a muzzle device designed to combine flash hiding capabilities with DeadAir Silencers KeyMount compatibility for AK-pattern rifles. It promises to offer both improved aesthetics and suppressor mounting options. This review will delve into whether the GFHC 14-1LH lives up to those promises and if it’s worth the investment for AK enthusiasts.
I was looking for a way to both reduce muzzle flash on my AK and add suppressor compatibility without significantly increasing the rifle’s overall length. Many muzzle devices sacrifice one for the other, but the JMac Customs GFHC 14-1LH Face KeyMount KeyMicro piqued my interest with its combined flash hider and KeyMount design. The ability to quickly attach a suppressor was the key feature that I was after.
Upon receiving the GFHC 14-1LH, I was immediately impressed with its robust construction. The nitride finish appeared even and durable, and the device felt solid in hand, suggesting a high level of quality. Its compact size was also a pleasant surprise, promising minimal added length to my AK platform.
Compared to other AK muzzle devices like traditional slant brakes or birdcage flash hiders, the GFHC 14-1LH stands out due to its KeyMount compatibility. I chose it over a standard A2 flash hider primarily for the suppressor mounting capability. Other KeyMount options from different manufacturers felt less rugged and more expensive.
My initial impression was cautiously optimistic. I was eager to test its performance but concerned about potential installation issues, especially given the need for shims and professional installation for suppressor use. The weight felt reassuring, but the complexity of proper alignment gave me pause.
Real-World Testing: Putting JMac Customs GFHC 14-1LH Face KeyMount KeyMicro to the Test
First Use Experience
My first testing ground for the JMac Customs GFHC 14-1LH Face KeyMount KeyMicro was at an outdoor shooting range. I mounted it on my Zastava ZPAP92 pistol, ensuring proper timing with shims and confirming alignment using a bore rod prior to firing. The rifle was chambered in 7.62x39mm.
The GFHC 14-1LH performed admirably in dry conditions, noticeably reducing muzzle flash compared to the un-braked muzzle. The recoil impulse felt manageable, though not dramatically different from other muzzle devices I’ve used. Attaching my Dead Air Sandman-S suppressor was quick and secure, thanks to the KeyMount system.
Getting the timing just right required some patience. Several tries were needed to correctly shim the GFHC 14-1LH to ensure a rock-solid mounting and a neutral bias. The instructions explicitly state that it may require professional installation – and this proved correct.
Extended Use & Reliability
After several range trips and approximately 500 rounds fired, the JMac Customs GFHC 14-1LH Face KeyMount KeyMicro continues to perform reliably. There are no signs of loosening or damage, and the nitride finish remains intact. It has become a standard feature on my AK pistol.
The device has proven to be durable, showing no noticeable wear or tear from repeated use and suppressor mounting. Cleaning is simple, requiring only a solvent and brush to remove carbon buildup from the flash hiding ports. I found that an ultrasonic cleaner makes the job very easy.
Compared to a previous experience with a cheaper, no-name muzzle brake, the GFHC 14-1LH is a significant upgrade. The JMac Customs product offers superior construction, reliable suppressor mounting, and effective flash hiding. The increased cost is well worth the performance and durability.
