Good day friends.. I just bought a DD M4V2 which ill be picking it up at my local FFL next week, hopefully. A newbie question, hope don't mind me asking. How often should i clean an AR15? Every 1, 2 or 3k rounds? I ordered 1k rounds of wolf 223 ammos from luckygunner.com. Quite cheap and good reviews eventhough made in Russia. Thank you for inputs.. appreciate it.
