This Griffin Armament adapter (brand part no. OPMEXT) provides a mounting interface for any Griffin Taper Mount muzzle device — long or short, any thread pitch — to attach to the Optimus Micro suppressor. It’s made exclusively for the Optimus Micro and will not fit any other Griffin suppressor. The Optimus Micro is a .22-caliber-only suppressor, and Griffin Armament warns that using it on a .30-caliber Griffin Taper Mount or any firearm over .22 caliber will damage the silencer. This Class 3 accessory is the mounting interface, not the suppressor itself.

Key Specifications

• Compatible with any Griffin Taper Mount muzzle device, long or short, any thread pitch.

Frequently Asked Questions

Can I use this with a .30-caliber Griffin Taper Mount or a larger-caliber firearm? No. Griffin Armament states the Optimus Micro is .22 caliber only, and using it on a .30-caliber mount or firearm over .22 caliber will damage the silencer.

Is this adapter itself an NFA item? No. It’s an ordinary Title I mounting accessory; the Optimus Micro suppressor itself is the separately-regulated NFA item.
