The Octane™ is a user maintainable, multi-caliber centerfire pistol silencer featuring a modular mounting system for use across a wide range of hosts. Innovative, high-strength, stainless steel CTA™ (Click Together Assembly) baffles are easily disassembled for cleaning and make the Octane the most durable pistol suppressor line on the market. This durability is a vital feature of the Octane and means that it can be used on everything from semi auto pistols to carbines to submachine guns – even hosts like the iconic H&K® MP5. In addition, the Octane can be used with 300 Blackout subsonic rifle ammunition.
