The Optimus Silencer is the most significant advancement in consumer silencer technology in the last decade. 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. Re configuring the suppressor with the included booster assembly and piston, the Optimus transforms into a high performance, reliable, 9mm pistol silencer.
