I just bought some more guns recently and I have this idea that I could keep an record of the amount of ammo fired through each gun. One benifit is that I would know when its time to replace certain parts before they break. Another is that if I was to sell one of my guns I would be able to tell the person buying how many rounds it has had fired. Anyone think this is a good I idea as well?? Wanna kill these ads? We can help!
