The Aurora-II is an update of the Fighter Pilot’s favorite wipe suppressor. Our engineers created the smallest lightest can on the market. The Aurora-II is threaded on both ends making it compatible with Metric and Standard thread pitches. The Aurora-II is made from Military Grade 70-75T6 aluminum with the internals composed of 8 neoprene wipes and 3 petroleum jelly-filled spacer baffles. Because it weighs 3.5 oz it does not require a Nielsen device. – Caliber: 9MM – Sound Tested: 137dB WET M&P9 M2.0 – Diameter: 1.125 – Overall Length: 3.5 Including Thread Protectors – Weight: 3.5 oz. – Mount Type: 1/2-28 or M13.5×1 LH Thread at Muzzle – Tube Material: 7075-T6 Aluminum – Full Auto Rated: No – Tube Finish: MIL-A-8625 Type II Class 2 Black Anodized
