The Breek Arms 3FO Flash Hider is a great way to reduce muzzle flash and improve your overall shooting experience. It is designed specifically for 9mm pistols and is compatible with all 1/2x28 threaded barrels. The 3FO's unique design uses internal threads to disrupt gas expansion, which helps to break down the gas even more and reduce muzzle flash significantly. This flash hider also features a sleek, low-profile design that will seamlessly integrate with your weapon system. In addition, it is made from durable 4140 steel with a Nitride finish for added strength and corrosion resistance. The external 13/16x16 threads allow a Breek Arms Castle Blast Shield (sold separately) to be used with this muzzle device by sliding it over the outside of the 3FO for easy installation. The Breek Arms 3FO Flash Hider is a great choice for anyone looking for a high-quality, effective flash hider for their 9mm pistol.
