A truly high-performance and versatile silencer, the Optimus™ can service many firearms from rimfire calibers up to 300 Winchester magnum. Utilizing full 17-4 stainless construction with user adaptable components the Optimus™ in its full-size standard configuration is a 9.4” 18.5 ounce, taper mounted 300 Winchester Magnum rated silencer. A 7.9 inch 16 ounce 308 rated Mid Size Taper Mount configuration can be attained using the optional minimalist brake shield. Reconfiguring the suppressor with the included booster assembly and piston, the Optimus™ transforms into a high-performance, reliable, 9mm pistol silencer.
