The Heresy Design SBF Safety Selector for the Steyr AUG A3 M1 (brand part no. HD-SS) replaces the factory selector on this bullpup platform with a purpose-built billet part finished in black. Heresy Design designs its AUG upgrades specifically around the AUG’s bullpup ergonomics, and this selector is shaped for quicker, more positive manipulation without changing the rifle’s factory safety function. It’s a drop-in swap for AUG owners looking to fine-tune controls without sending the rifle out for custom gunsmithing. The billet construction holds up to repeated use better than the stock polymer-based selector on some AUG variants.
