 Brake and redirect combos are machined in America with quality and price in mind. This brake is designed to reduce recoil when used alone and with the redirect it is designed to reduce sound by projecting gasses and sound down range to desired target.

With our unique design the brake slides over the barrel to give a sleek look and uses .013 Viton O-ring for timing. Thread protector is an optional purchase, If you would like it please add this to your cart before placing order, it is a separate item.
