Basically, back in 2011, the US Marines were in an intense firefight and then the armorer at Barrett in Tennessee, Don Cook, who was also a Marine veteran received a call from a marine unit, and they were in an intense firefight, and what happened was that a marine bent the ears of the rifle and it was not firing consistently. Thankfully Don knew what to do, and he guided them through how to fix the problem. 45 seconds later, the crew was back in business and he basically saved the unit.
What can we learn from this everyone?
Barrett will always be there to help, even when you are in an intense firefight!
