SEM Flash Hider for AR-15 cal..223 Rem (5.56/45) — 1/2"-28 UNEF Thread

The SEM flash hider is designed for.223 Rem (5.56×45 NATO) caliber carbines, easily installed on AR-15 platforms and compatible barrels with a 1/2"-28 UNEF muzzle thread. The design consists of three main components: a threaded body, a nut, and an internal funnel-shaped part that effectively disperses and suppresses the flash generated when propellant gases exit the barrel. Thanks to this design, the flash hider almost completely eliminates visible muzzle flash during firing, which helps maintain position concealment and prevents washout when using night-vision sights. This is especially important for night shooting or in conditions where shooter detection is critical.

The flash hider from the SEM brand has optimal dimensions for tactical and practical use: an overall length of 100 mm, a diameter of 34 mm, and a weight of 230 g. The insert is made of heat-resistant, refractory austenitic AISI304 steel, ensuring resistance to high temperatures and a long service life. The body and nut are made of 40x steel, and the surface has a protective chemical oxidation coating, which increases corrosion resistance and durability.
