Kak Industry
The Kak Industry 1/2x28 Retro Duckbill flash hider brings vintage aesthetics and genuine functionality to your modern rifle build. Styled after the classic flash hiders of the mid-1960s era, this muzzle device is American-made and engineered to work with centerfire rifles up to .30 caliber. If you're building a retro-inspired AR or want authentic period-correct ergonomics on a modern platform, this duckbill-profile device delivers both character and practical flash signature reduction.
Kak Industry designed this component to fill the gap between premium-priced optics and budget-grade parts—solid American manufacturing at a price that won't break the bank. The 1.76-inch overall length keeps the profile compact while the 1/2x28 thread pattern ensures compatibility with most modern .223/5.56 and smaller-bore centerfire rifles. Installation is straightforward on any barrel threaded to spec.
Whether you're period-correct-minded, aesthetically drawn to classic lines, or simply looking for a no-nonsense muzzle device with proven design pedigree, this retro duckbill is a legitimate choice for precision rifles, plinkers, and hunting builds alike. Crush washer not included, so source that separately for proper installation.
