Arsenal AK-133S Flash Hider Features The Arsenal AK-133S Flash Hider reproduces the four-port egg beater design standard on Bulgarian military AK rifles giving shooters an authentic look paired with modern materials. Built from stainless steel rather than the original mild steel it resists corrosion and wear far better over years of use and cleaning. The Cerakote finish adds an additional layer of protection against the heat and fouling that muzzle devices are routinely exposed to during firing. Manufactured in the USA by Arsenal this flash hider also qualifies as a 922r compliance part for AK platform builds that require US-made components. Threaded for 24x1.5mm right hand threads the AK-133S Flash Hider is designed to fit the factory barrel threads found on 7.62x39 AK pattern rifles using that pitch. Its four-port design is engineered to redirect muzzle gases and reduce visible flash helping preserve the shooter s night vision during low-light use. Finished in black it is styled to match the rest of a Bulgarian pattern AK build without looking out of place. For AK owners seeking an authentic Bulgarian profile with the added durability of stainless steel and Cerakote the Arsenal AK-133S Flash Hider is available for sale at GrabAGun.
