The Optimus Micro re-defines the rimfire class of suppressors by offering the most durable and versatile rimfire suppressor ever designed. Utilizing state of the art manufacturing and heat treated 17-4 stainless steel throughout, the Optimus Micro supports 5.56mm cartridges out of the box using the included 1/2×28 direct thread mount. Interlocking HEDP patented baffle technology provides uncompromising sound performance while ensuring durability and proper orientation. Patent pending dual taper locking front caps ensure the suppressor can be used vigorously without fear of unintentional disassembly. Additionally, the suppressor supports 3 lug mounting with the use of the Griffin 3 Lug Kit (which is compatible with the Optimus 9mm, Revolution and Resistance suppressors). Taper Mounts can also be used with the Optimus Micro Taper mount accessory interface. In the Taper Mount configuration, the Optimus Micro is rated for 22-250 caliber, on 22″ or longer barrels.
