Let’s Talk About KAK Extended 5/8-24 Flash Can
The KAK Extended 5/8-24 Flash Can from KAK Industry is designed to redirect muzzle gases and flash forward, enhancing the shooter’s experience, particularly on short-barreled rifles. This solid 6061 aluminum device boasts a military-grade hard anodized finish and wrench flats for easy installation. It promises to improve the look and feel of any compatible firearm.
My journey to the KAK Flash Can started with a common problem: excessive concussion and muzzle flash from my 7.62×39 AR pistol build. A short barrel means significant unburnt powder exiting the muzzle, resulting in a loud and often unpleasant shooting experience, especially indoors or around other shooters. I needed a solution that wouldn’t require extensive modifications or NFA paperwork, hence a flash can rather than a suppressor.
The KAK Flash Can arrived neatly packaged. Its solid construction was immediately apparent, and the hard anodized finish felt robust and ready for the rigors of the range. The weight, while noticeable, felt appropriate for its size and intended purpose. The simple, cylindrical design gave it a no-nonsense, tactical aesthetic.
I considered a few other options, including the Seekins Precision AR Flash Hider and the Noveske KX5 “Pig.” Ultimately, the KAK Flash Can won me over due to its combination of extended length, reasonable price, and positive user reviews about its effectiveness in directing muzzle blast forward. I was hoping it would significantly reduce the side concussion.
My initial impression was positive. The build quality exceeded my expectations for a device in this price range. I was excited to see how it would perform on my AR pistol.
Real-World Testing: Putting KAK Extended 5/8-24 Flash Can to the Test
First Use Experience
My first outing with the KAK Extended 5/8-24 Flash Can was at an outdoor range. I mounted it on my 7.62×39 AR pistol with a 7.5-inch barrel. I primarily used standard 123-grain FMJ ammunition.
The difference was immediately noticeable. The concussive blast felt significantly reduced, and the muzzle flash was directed forward. The report was still loud, but the perceived noise level at the shooter’s position was lower. The rifle felt more controllable.
It performed well under sunny conditions. I didn’t experience any issues with the device coming loose or affecting the rifle’s cycling. The improved recoil management contributed to faster follow-up shots.
I didn’t need any time to get used to it. Installation was straightforward using a standard wrench. The only slight surprise was the amount of carbon buildup after a few magazines.
Extended Use & Reliability
After several months of regular use, the KAK Extended 5/8-24 Flash Can has held up admirably. There are no signs of significant wear and tear. The hard anodized finish still looks new, despite being subjected to heat and carbon fouling.
Cleaning is relatively easy. A solvent and a brush easily remove carbon buildup from the interior and exterior surfaces. I’ve only needed to clean it every few hundred rounds.
Compared to my previous experiences shooting the AR pistol without a flash can, the KAK device is a game-changer. It significantly enhances the shooting experience, making it more enjoyable and less fatiguing. The device definitely outperforms my expectations.
Breaking Down the Features of KAK Extended 5/8-24 Flash Can
Specifications
- Caliber: Designed for calibers up to .45, making it compatible with a wide range of firearms.
- Thread Pitch: 5/8-24, a common thread pattern for larger caliber AR-platform rifles, including .308 and 7.62×39. This ensures compatibility with many popular barrels.
- Material: 6061 Aluminum, offering a balance of strength and weight savings. Aluminum construction keeps the overall weight down.
- Finish: Black Hard Anodized, providing a durable and corrosion-resistant surface. Hard anodizing increases resistance to scratches and wear.
- Length: 5.00 inches, extending the barrel length and increasing the effectiveness of flash and sound redirection. The extended length helps push the muzzle blast further away from the shooter.
- Diameter: 1.360 inches, offering a substantial profile without being overly bulky. This provides ample internal volume to manage muzzle gases.
- Weight: 7.34 oz, adding a noticeable but manageable amount of weight to the muzzle. The weight is a tradeoff for the increased performance.
- Wrench Flats: 3/4 inch, providing a secure grip for easy installation and removal. Standard wrench size simplifies the installation process.
These specifications matter because they directly impact the flash can’s performance and durability. The aluminum construction keeps the weight down. The hard anodized finish ensures longevity. The extended length optimizes its effectiveness in directing muzzle gases.
Performance & Functionality
The KAK Extended 5/8-24 Flash Can excels at redirecting muzzle gases and flash forward. It minimizes side concussion and perceived noise levels for the shooter. It does not, however, reduce recoil or flash signature in a significant way.
Its primary strength is its ability to improve the shooting experience, particularly on short-barreled rifles. It makes shooting more comfortable and controllable. One weakness is that it doesn’t significantly reduce the overall flash signature, just redirects it.
It meets my expectations for a flash can in this price range. It’s a simple, effective device that does exactly what it’s designed to do. I was hoping for more flash reduction, but the decreased concussion is the real win.
Design & Ergonomics
The KAK Flash Can features a straightforward, cylindrical design. The 6061 aluminum construction feels solid and durable. The weight is noticeable but not excessive.
The simple design makes it easy to install and use. There is no learning curve. It is comfortable to use.
Durability & Maintenance
The KAK Extended 5/8-24 Flash Can is built to last. The hard anodized finish provides excellent protection against wear and corrosion. Regular cleaning is essential to remove carbon buildup, but the process is simple.
I expect it to last for many years with proper care. The build quality suggests a long service life.
Accessories and Customization Options
The KAK Extended 5/8-24 Flash Can doesn’t come with any accessories. It is a standalone device designed to be mounted directly onto a threaded barrel. There aren’t many customization options for a device like this, beyond potentially cerakoting it in a different color.
It is compatible with any AR-15 or AR-10 platform rifle with a 5/8-24 threaded barrel. It can be used in conjunction with other muzzle devices.
