Product Description The Spikes Tactical Barking Spider 2 is a Krinkov-style muzzle brake designed to drive noise, blast, and concussion forward and away from the shooter. Built to withstand full-auto and high-volume fire, it uses a supported blast cone design to help prevent sagging under extreme heat. CNC machined from billet 4140 chromoly bar stock with a durable Black Nitride QPQ finish, it features a weight-reducing ball-dimpled body and a pre-drilled housing for pin-and-weld applications. Its modular design allows quick configuration changes by swapping end caps and accessories.
