The Aurora-II is an update on the original 9mm wipe suppressor, offering users the smallest and lightest pistol caliber suppressor on the market. The Aurora-II is threaded on both ends allowing it to be mounted on both Metric and Standard thread pitches and is composed of 8 neoprene wipes along with 3 petroleum jelly-filled spacer baffles for maximum sound reduction. The low weight of the Aurora-II also means that it can be mounted to common browning-style tilting-barrel pistols without the need of a booster device. This model features an all-black finish. Wipe components are defined by the BATFE as silencer parts and must be replaced by the manufacturer. The Aurora-II cannot be used with hollow point or expanding ammunition.
