What is better than First Responder Fuel by itself? Ammo and First Responder Fuel! Welcome our new retail affiliate R2 Ammo where you can find our entire line of products like our award winning Off Duty PM and our Firehouse Brew Coffee line. So drop on by, pick up some ammo and First Responder Fuel products. And as usual, a portion of every sale is donated to the Brotherhood of Heroes Foundation a non profit charity that supports first responders and their families during times of crisis.
