The Badger Ordnance Micro FTE Muzzle Brake is an even smaller version of our FTE brake and designed for the AR-10/15 platform. While a much smaller design, it still maintains enough surface area to make it a very effective brake. The ports are oriented to the sides to reduce ground blast. The Micro FTE installs using the provided crush washer. It is machined from 4140 steel and Manganese Phosphate finished.
