Phase 5 littleBOY Hex Brake, 5.56 NATO, Black

The Phase 5 littleBOY Hex Brake (brand part number littleBOY-556) is a compact 5.3-ounce muzzle brake for 5.56 NATO AR-15 barrels, built as a scaled-down version of Phase 5’s original FATman Hex Brake. It carries a single large, ventilated baffle chamber that generates the compensation needed to cut felt recoil, engineered so the chamber wall sits as close to the barrel’s crown plane as possible without robbing the barrel of its accuracy. The iconic Phase 5 hex-shaped body gives it the custom-build look precision rifle and competition shooters look for.
