The Hellfire Self Timing Brake system is not just another knockoff copy of existing self timing brakes. It was engineered from the ground up to be different, easier to install, and much more versatile. Suppressor mount allows you to use your compatible suppressors with the Hellfire Self Timing Brake system by simply removing your Hellfire Brake. The Generation 2 mounts no longer use a collar like the muzzle brake. These mounts get torqued into your suppressor and therefore allow your suppressor to become a direct thread onto the Hellfire adapter.

Mounts get torqued into your suppressorAllows the mount to be much more compact, and adds very little to the overall length of the systemGen 2 comes with a Hellfire Wrench
