Phase 5 Weapon Systems recently completed their lineup of FATman and littleBOY Hex Brakes with the addition of the 9mm/7.62×39/6.8 model for both FATman (dual chamber) and littleBOY (single chamber) brakes with 1/2×36 threads. This now brings the total to 6 different muzzle brakes in the Hex Brake series including the 5.56/.223 with 1/2×28 threads & 7.62×51/.308/300BLK with 5/8×24 threads for FATman and littleBOY models as well.

I have all except for the 9mm model right now and they are actually a very cool muzzle brake. They are on the larger side but at the same time they have a collar that covers a bit of the end of the barrel as you thread them on. They have a pretty stout look too. These are definitely work taking a look at if you’re in the market for a new muzzle device.
