On the heels of their hugely popular 7.62mm Optimus, Griffin Armament now parlays that greatness to the rimfire category of silencers. Because their new and pioneering Optimus Micro also effortlessly runs on your chosen 5.56mm rifle when the accompanying 1/2×28 direct-thread mount is utilized, this user-serviceable Griffin Armament unit is as versatile as it is effective. Without question, durability and versatility are maximized by the 5.3-inch, 8.5-ounce Optimus Micro masterpiece.

Producing out of Wisconsin, the Griffin Armament team relies on detailed designing and unparalleled testing to create silencers in each classification. Their Optimus Micro revelation redefines the rimfire group of suppressors. Be the first at your gun run to experience the quiet!

Further Intel

An all-stainless steel can, the Optimus Micro offers shooters the toughness required to handle a wide variety of calibers (e.g., .22LR, .22WMR, .17HMR, and 5.7mm) without sacrificing performance. To that point, if 5.56mm is your preferred cartridge, the included 1/2×28 mount will put a smile on your rifle’s barrel. By implementing an interlocking baffle system, Griffin Armament ensures the Micro delivers impressive sound reduction. Moreover, its dual taper-locking endcaps elicit confidence that the suppressor will withstand a thumping when used on various firearms. The Optimus Micro’s unmatched versatility and durability make this unit a must-add to your rimfire silencer collection.
