Do you have to use a bore brush everytime you fire your non chrome lined barrels? Whta does bushmaster means when they said "some barrels are ruined by Overcleaning" Can you just clean with a patch w/ CLP? even if your barrel is not lined? As a rule of thumb, how many passes with a bore brush is needed for every round(s) fired? Some said "1 pass for every two rounds fired" it sounds too much for me to brush bore 50X for every 100 rounds fired!!

You should allways bore-brush any barrel...

However, OVER-CLEANING, especially if you use abrasive cleaners like JB Bore Paste, can easily ruin a barrel...

Basically, get it clean, but not Parade clean...
