BTBFAs weighs about half the weight of the current in-service bayonet, and are optimized for the new Thales F3A1 blank round. A major advantage over conventional Blank Firing Attachment (BFA) is that the BTBFA is designed to actually stops an accidental firing of a live round, before it leaves the barrel, compared to conventional BFA which provides the back pressure to enable blank firing. According to Thales, BTBFA can stop a live round travelling at 800 m/sec down the barrel, in the space of 6cm. Thales Australia has also designed BTBFAs for use with other in-service weapons.
