The Barking Spider is designed to redirect noise, blast, and concussion forward and away from the shooter (down range). It also increases the back pressure which in turn can increase the reliability in a short barrel application where dwell time has been sacrificed for barrel length or the increased pressure is needed for sub sonic or weak ammo. The Barking Spider can be used on any barrel length but it really shines in short barrel applications. The Barking Spider is Modular in that it can accept multiple different end caps, attachments, and thread protectors. The Modularity allows the operator to tailor the weapon system for a specific application. The front end of the Barking Spider has an integrated striking device or glass breaker with 1 1/8″ wrench slots for easy disassembly making cleaning and maintenance a breeze. The internals come out the front leaving the body attached to the barrel. This allows you to pin (perm attach) the body to the barrel to meet 16″ OAL requirements yet still be able to disassemble the muzzle device from the front. The Barking Spider 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. The Barking Spider, patent pending, is 100% Made in the USA and features a Lifetime Warranty!
