Quote History The problem with these threads is that the guy says the range sees 400k rounds per month across all firearms. Even if the ak saw 1% of that, that's still 4k rounds in a month. That's quite a lot of ammo to be shooting per month.
Now if you shot 5k in a day, that's a lot different than shooting 5k over the span of 5 years.
Point is, the wear and tear of a barrel all depends purely on how fast you shoot and how often. If you shot 1 round per second, and don't let the gun heat up that much, your rifle will last for 10s of 1000s of rounds.
There's no way to determine if 5k is a high mileage or not as it depends more so on the frequency and length and how well you clean your rifle.
It's sort of like a car. If you drove under 20 miles a day, never driving faster than 45mph, and keeping up with the yearly maintenance, your car will last a heck of a lot longer than someone who drives 50 miles a day, and drives 60 mph on average.
