Description
MPN: 410-1702-005-M
Features:
- Built for Big-Bore Performance: Designed specifically for .458 SOCOM platforms where larger bore diameter is required
- Hardened Steel Construction: Manufactured from hardened steel to handle the increased pressure and recoil of big-bore cartridges
- Effective Flash Suppression: Multi-slot design helps disperse and reduce visible muzzle flash, especially useful in low-light conditions
- Threaded for .458 SOCOM Barrels: Compatible with standard 5/8”×28 threading commonly used for .458 SOCOM builds
- Simple, Hassle-Free Installation: No crush washer or timing hardware needed—install directly and get back to shooting faster
- Heat & Corrosion Resistant Finish: Built to withstand high round counts and harsh shooting environments
- Made in the USA: Precision-machined by KAK Industry for durability and reliable performance
Specifications:
- Caliber: .458 SOCOM
- Material: Steel
- Finish: Phosphate
- Weight: 2.3 oz.
- Length: 2.25"
- Outer Diameter: 0.94"
- Thread: 5/8"-24
Compatibility:
- Any .458 SOCOM rifle/carbine barrel with 5/8"-24 thread pitch.
Includes:
- 1x KAK Industry .458 SOCOM Hardened Flash Hider
Installation Note: This muzzle device does not require a crush washer for proper installation. It is designed to shoulder directly against the barrel and will function correctly without timing. A washer is only necessary if you wish to index or time the ports in a specific orientation.
Details:
A .458 SOCOM does not behave like a 5.56. The gas volume is heavier, the pressure curve is different, and the muzzle sees significantly more stress per shot. That matters because many flash hiders designed around intermediate calibers simply aren’t built for that environment long term. This model is.
The defining characteristic here isn’t the prong count or the profile — it’s the hardened steel construction. On big-bore AR platforms, softer flash hiders can begin to show deformation at the tips of the prongs over time. The repeated blast erosion from large powder charges accelerates wear, especially during sustained firing. Hardening slows that process and helps the device retain its geometry instead of rounding off or peening prematurely.
That durability matters more on .458 SOCOM than on smaller calibers because once prong edges start degrading, flash performance can change. Maintaining edge integrity helps keep gas dispersion consistent.
Why Open-Prong Design Still Makes Sense on .458 SOCOM
Large-caliber cartridges often produce visible flash, particularly in low light or when running shorter barrels. The open-prong layout breaks up the gas plume as it exits the bore, allowing it to disperse before it can ignite into a concentrated fireball.
This isn’t a recoil-reducing device. It does not redirect gas aggressively or attempt to mitigate rearward impulse like a brake. On a .458 SOCOM, recoil mitigation is typically addressed through mass, gas system tuning, or muzzle brakes. This flash hider stays in its lane — signature reduction without added concussion to shooters beside you.
For shooters who frequent indoor ranges or shared firing lines, that distinction matters.
