Manticore Arms Brass Buster Features The Manticore Arms Brass Buster is a polymer brass deflector designed to redirect hot ejected casings away from the shooter s face and neck an especially important feature on bullpup rifles where the ejection port sits close to the shooter. Its ambidextrous design allows the deflector to be used whether shooting from the right or left shoulder giving left-handed shooters the same protection and comfort as right-handed shooters on these compact platforms. The polymer construction keeps the part lightweight adding negligible weight to the rifle while still standing up to the heat and impact of ejected brass over repeated firing. Because it is removable shooters can take the deflector off entirely when not needed or swap it between compatible rifles. Compatibility spans the Steyr Aug all generations of the MSAR STG-556 and the E4 as well as the full TPD AXR series of rifles making this a versatile accessory for owners of this bullpup family. The package includes the brass deflector itself along with an instruction sheet making installation straightforward without needing a gunsmith. For shooters who switch shoulders during training or simply want added protection from hot brass during extended range sessions the Brass Buster is a simple practical upgrade. The Manticore Arms Brass Buster is available for sale at GrabAGun for Steyr Aug and compatible rifle owners seeking improved shooter comfort and safety.
