Quick Overview


Not only does the SilencerCo Octane 45 HD perform exceptionally well on handguns, submachine guns, and subsonic rifles, it is also user serviceable.  Innovative, high-strength, CTA (Click Together Assembly) baffles allow the silencer to be dissembled with ease for cleaning and maintenance.  The SilencerCo Octane 45 HD features a modular mounting system, allowing transfer between hosts with a wide variety of pistons available.  Although it is a multi-caliber centerfire pistol silencer, the SilencerCo Octane HD can also be used with subsonic 300 Blackout rifle ammunition.  Model #SU588



The Octane 45 can best be described as a great traditional pistol suppressor.  The stainless steel baffles not only provide durability, but are suitable for harsher methods of cleaning.  This allows the shooter to use cast lead projectiles or shoot 22LR through the Octane without worry of permanent lead accumulation.  A huge variety of pistons, mounts, 3-lug solutions, and now ASR mounting system allow for versatility, and assurance that the Octane 45 can be fit onto any firearm you’re looking to suppress.
