I will be shooting my Colt LE6920 for the first time in the morning. I have heard all kinds of things about how to break in a new rifle including pouring motor oil down the barrel, or cleaning the rifle after each shot for the first several rounds, to just going out and shooting it. I cleaned and lubed the gun last night. How do you guys break in a new rifle? TIA Wanna kill these ads? We can help!
