Sometimes shorter is better, right? The Shadow Flash Hider is a more compact version of our standard Eclipse flash hider that is optimized for 1/2x28 tpi threaded guns and will work with any round under 9mm in diameter (i.e. 300 Blackout, 5.56mm, .22LR, etc). The design features three short, straight prongs for better flash hiding capability. The Shadow Flash Hider is manufactured from 8620 steel, heat treated, and coated in black oxide. It is marked "MA" and "9mm" to denote that it is made right here in the USA by Manticore Arms for any weapon up to 9mm caliber and comes with a crush washer. It is 1.75" long, weighs 2.4 ounces, and is a standard 22mm diameter allowing for the use of most standard NATO muzzle accessories.
