Advanced Armament 64242 Blackout 90T Taper 5.56x45mm NATO 1/2"-28 tpi 2.50" Black Nitride Aluminum

For the past decade, the military chosen and adopted Blackout flash hider has been considered one of the most effective small-arms flash hiders in the world. The three prong design all but eliminates visible flash on barrels as short as 10 inches. A high-strength, corrosion-resistant aerospace alloy and ultra-hard SCARmor finish provide the highest level of durability. This 90 tooth ratchet taper is for AAC's SR-5 for 5.56mm hosts.
