SilencerCo Octane 45k





Engineered for those interested in the shortest hearing safe version of the SilencerCo Octane 45.  The Octane K 45 features a dark grey Cerakote finish to reduce their visual signature compared to traditional black anodizing.  At 9.5 ounces, the Octane K 45 provides an option for those looking for a minimalist profile without sacrificing the need for a hearing-safe alternative to unsuppressed gunfire.  In addition to weight, the length of the Octane K 45 version was also reduced by nearly 2 inches when compared to the standard Octane 45 suppressor.

The Octane K 45 features an innovative, high-strength, CTA (Click Together Assembly) baffles allow the silencer to be dissembled with ease for cleaning and maintenance.  The SilencerCo Octane K 45 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 K 45 can also be used with subsonic 300 Blackout rifle ammunition.


The Octane 45 became popular for a number of reasons.  A wide variety of mounting solutions, full-auto rating, and being serviceable are just a few.  There were some shooters that enjoyed the features of the full size Octane 45, but desired a shorter suppressor that was still hearing safe.  The Octane 45K fills this role.  Being able to access the CTA baffle stack for maintenance lets the suppressor be used with cast lead projectiles, as well as 22LR.  With the release of the ASR Nano mount, the Octane 45K can be used on pistol caliber carbines and submachine guns without having to rely on 3-lug as the only quick disconnect option.
