The Gemtech Aurora II 9mm suppressor (Gemtech part no. 12123) is a small, light wipe-style can built from military grade 70-75T6 aluminum in a black finish. Gemtech threads it on both ends, which lets one suppressor mount to barrels cut for either metric or standard thread pitches. Inside, eight neoprene wipes and three spacer baffles filled with petroleum jelly handle the sound reduction, and the can is light enough that it needs no Nielsen device. The Aurora II is an update of an earlier Gemtech wipe design, kept compact so it does not throw off the balance of a 9mm pistol or carbine. It is a straightforward choice for a shooter who wants a lightweight 9mm can and is willing to leave the wipe service to the factory.

Key Specifications

• The caliber is 9mm, the host cartridge this can is built around.
• The tube is military grade 70-75T6 aluminum, which keeps the can light.
• The finish is black, which matches most pistol and carbine hardware.
• The width is 1.13 inches, slim enough to sit comfortably on a slide or barrel.
• The can is threaded on both ends, so it can be fitted either way around.
• It accepts metric and standard thread pitches, which widens the list of 9mm barrels it can mount to.
• The core holds eight neoprene wipes, which provide the wipe seal that does the work in this design.
• It also has three petroleum jelly-filled spacer baffles that separate the wipes inside the tube.
• It needs no Nielsen device, because the can is light enough to cycle a tilting-barrel pistol without one.
• Wipe replacement is done at the factory, where Gemtech repacks the suppressor when the wipes wear out.

Frequently Asked Questions

Can I shoot hollow points through it? No. Gemtech states that the Aurora II cannot be used with hollow point or expanding ammunition, because those bullets can cause catastrophic damage to the suppressor and possible injuries.

What thread pitches does it fit? It is threaded on both ends and fits metric and standard thread pitches, so check your barrel thread before ordering.

Do I need ATF approval to buy this? No. As of October 9, 2026, ATF no longer requires Form 4 approval, registration or a tax stamp for suppressors. It transfers on a Form 4473 with a background check through a Class 3 (SOT) dealer. State and local laws still apply.
