Griffin Silencer Optimus Micro Modular .22LR Suppressor - Versatile & Compact Noise Reduction Solution

The Griffin Armament Optimus Micro is a modular .22LR suppressor built to handle far more than just rimfire plinking. This compact, versatile can redefines what you can expect from a .22 suppressor by supporting everything from .22 LR and .22 WMR out of the box all the way up to centerfire cartridges like .223/5.56mm, .22-250, and .224 Valkyrie—depending on your mounting setup and barrel length. Whether you're running it on a bolt-action .22 rifle, a 5.7mm pistol, or threading it onto a 14.5-inch 5.56mm barrel, the Optimus Micro adapts to your rig without compromise.

Built from heat-treated 17-4 stainless steel throughout, the Optimus Micro uses Griffin's patented HEDP interlocking baffle technology to deliver sound reduction that actually performs while resisting the wear that comes with sustained use. The patent-pending dual-taper locking front caps mean you won't worry about the can walking off during aggressive shooting sessions. At just 8.5 ounces and 5.3 inches in its standard direct-thread configuration, it's compact enough not to burden your rifle's balance, yet engineered tough enough to handle centerfire duty when mounted via taper or 3-lug adapter.

The suppressor ships ready to thread onto 1/2x28 hosts and includes five baffles, an end cap, lock ring, direct-thread mount, manual, and a microfiber pouch. Want to run 3-lug or taper-mount configurations? Those interfaces are sold separately, but they unlock support for larger centerfire calibers and different mounting platforms—giving you years of flexibility as your firearms collection grows.

Yes, in direct-thread configuration it's rated for .223/5.56mm on barrels 14.5 inches or longer. For shorter 5.56mm barrels (12.5 inches), you'll need to use the optional taper-mount configuration.

Griffin also offers optional 3-lug and taper-mount interfaces (sold separately) that expand compatibility to additional host firearms and calibers.
