Griffin Armament Optimus Series
The Griffin Armament Optimus family offers full-spectrum modularity in a single user-serviceable suppressor. The Optimus (full size) transforms across multiple configurations — from rimfire all the way up to .300 Win Mag — and reconfigures as a 9mm pistol suppressor with the included booster assembly. The Optimus Micro is a dedicated ultra-durable rimfire suppressor that also supports 5.56mm and .22-250. Both use 17-4 PH stainless steel throughout with patent-pending dual taper-lock interfaces for secure, tool-free disassembly. User serviceable for easy cleaning. Manufactured in Watertown, WI.
