The HELLFIRE 2P Muzzle Brake is designed to provide an optimized brake for Semi-Automatic and/or hunting weapons systems with barrels of 20″ or less. This brake will offer the greatest performance possible while maintaining shooter comfort.

Part of the Patent Pending HELLFIRE Modular Brake System

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 two caliber selections available for the HELLFIRE 2P 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/308 – Good for any bullet caliber up to and including 0.308, ie 6.5mm, 7mm, 284, 270, (Magnums OK)
  
• 9mm – Good for any bullet caliber up to and including 0.338, (Magnums OK)

Notable Features

• Extremely easy installation, brake WILL NOT turn as you torque the collar to lock.  No more guessing where the brake ports will line up once you tighten it down!
• Simple round knurled nut that requires no tools to time the brake.
• Return to zero is excellent.  This means removal of your brake and re-installation will not require a zero change.
• Simply torque the universal adapter onto your barrel with a 5/8″ wrench, this piece never has to come off.  Next, LEFT HAND thread the brake/collar assembly onto the adapter until it is almost snug.  Now rotate the brake until it is level, push the brake into the adapter and you will feel it lock onto the taper.  Now tighten the collar fully by hand, and you are done!

Maintenance

Maintenance on any muzzle brake is essential.  Just like your barrel, muzzle brakes need tp be cleaned.  Over time carbon will build up in the ports, mainly the last port as the first two are semi-self cleaning from the muzzle blast.  When this carbon builds up, it will eventually get to the point that bullets can actually strike it.  Depending on your shooting regimen you may not notice this, you might just call it a flier.  But in a competition when you need every round to impact, this is critical.  Carbon bullet strikes are a worst case scenario, but the buildup can also cause accuracy or POI issues just due to airflow changes in the brake ports.

NOTE: The use of Lemishine (or any citric-acid cleaner) or CLR to clean your brake will likely discolor the black nitride, and will void the lifetime warranty of your product. Don’t do this. Seriously. It’ll turn pink and you’ll feel like an idiot. 

The best cleaning method for any muzzle brake is PREVENTATIVE MAINTENANCE.  If you clean the brake every time you clean the barrel (200-400 round intervals, shorter for 6mm rounds) it will make your life much much easier.  With that being said, just soak the brake in a carbon cleaner like Boretech C4 and all the carbon should come right out, especially if you have a Black Nitride brake.  Raw stainless brakes can be more challenging to clean because the surface is more porous.  If necessary, you can use any kind of cleaning brush to aid in the removal of carbon from the ports.  Black Nitride is harder than any material they attach to a brush, so you will not scratch the surface.  Raw stainless may scratch if you use a stainless or other harder bristle brush.

If you decide to wait until 1000 rounds or more, you will have a lot of carbon buildup in the ports which will take some effort to remove.  Best method here is probably to soak for a day or two in C4 and use a pick to get the big chunks out.  Then follow the above method to get the remainder off.

You should also clean your Universal Adapter with the same care.  Every time you clean your barrel, let the carbon cleaner from patching the barrel soak on the muzzle for a few minutes and use a q-tip to wipe any carbon from the barrel crown and inside the end of the adapter.  Soak a patch in carbon cleaner and wipe the taper surface of the adapter off.  If there is persistent carbon on the surface, use steel wool to remove, it will not damage the surface.
