I can easily shoot 1 aimed shot per second with my AR, and after a couple mags through it, the barrel is pretty hot -- too hot to touch for more than a moment, anyway. The same is true for my FAL, however, it heats up easier.
How hot is "too hot"? I don't want to do any permanent damage to my barrels, or severely reduce their lifespan. Is this even a concern?
thanks
