Very clean look, works great - Phase 5 Weapon Systems Inc Littleboy Hex Brakes

This brake was absolutely perfect for the look I wanted. I have it installed on a CMMG 300 series Mk57 upper chambered in 5.7×28mm. The 5.7 is already a very low recoil round & with the lil boy installed it's like a .22LR! The CMMG 300 series uppers have a 5" barrel with a 4.5" handguard & this brake gives it that perfect clean, continuous look I was looking for while also keeping it as short as possible. The lil boy is 2.5" overall, but the 1st inch of the brake slips over the barrel before engaging the barrels threads, realistcally making it a 1.5" single baffle brake. Also the inner diameter of my handguard is 13/8", & this brake fits perfect, but if ur handguard is thinner than that it will not fit under it...If ur looking for style & functionality & ur trying to keep ur barrel as short as possible this is the brake u wanna get. It's super well made & I think has a phosphate finish or something similar. I will definitely be getting the Fatman, the larger double baffle version of this brake for my next build where length isn't an issue.
