The Deflector Brake was specifically designed to fit on standard MIL-SPEC style AR brass deflectors as shown. It will work with other styles and with many calibers but, results are not guaranteed. Although the Deflector Brake can take a lot of abuse it is recommended to swap it out after approx. 1000 rounds to maintain the desired effects. Please read all the directions to achieve the best results. Results will vary as no 2 rifles or shooting conditions are the same.
