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 extremely effective, easier to install, and much more versatile.  Read more on all of its advantages below:

Caliber Selection

In order to simplify the choices, we have four caliber selections available for the HELLFIRE brake.  The difference in efficiency between using a caliber specific brake bore, and the next size up is so minimal if not non existent that we decided to simplify things in order to lower overall costs to you the consumer.  As you can imagine, trying to stock the exact quantities required of six or so different calibers would be impossible.

223/6mm – Good for any bullet caliber up to and including 0.243 (6mm), ie 223, 5.56 NATO, 204, 17 cal, etc

6.5mm – Good for any bullet caliber up to and including 0.264 (6.5mm), ie 257, (Magnums OK)

7mm/308 – Good for any bullet caliber up to and including 0.308, ie 7mm, 284, 270, (Magnums OK)

338 – Good for any bullet caliber up to and including 0.338, ie 338WM, 338LM, 338NM, 338 Edge (5/8-24 is still max thread size!!!)
