Few civilians will ever NEED to shoot that much ammo with out cleaning.
I agree with you to a point however did you ever fire more than 300 rounds from the M16 and were unable to clean it. Actually accuracy is not a factor because you are providing supressive fire. How do you clean the rear locking lugs within the barrel with a chamber brush? Robo, I ask these guestions because I don`t know.
