The Barking Spider is designed to redirect the noise, blast, and concussion forward away from the shooter (down range). It was specifically designed to handle full auto and high volume fire. The Barking Spider features a cutting edge blast cone design which is supported in both the front AND the rear. This feature not found on any other Krinkov muzzle brake eliminates the cone from sagging in extremely high temperatures. It is CNC machined from Billet 4140 Chromoly BAR stock. It’s ball dimpled to reduce weight and to help dissipate heat. The body comes pre-drilled for pinning to the barrel. The body is the correct length to make a 14.5″ barrel into 16″ OAL when perm attached. The body is heat treated and features an extremely durable Black Nitride QPQ finish. It includes a thread protector which covers the teeth on the striking device when it’s not in use. It also includes a 5 prong Helix flash suppressor cap which greatly reduces the flash being thrown down range. The Modular design allows you to change configurations around in seconds by simply unscrewing the attachment and screwing on a different one.
