    I fored 10 rounds and ranthe bore snake through every 10 rounds through 50-100. the every 20 rounds for the next 150. From 200 -500 I ran the bore snake through every 50 rounds and cleaned with Hopps #9, brass brush, patches followed by patches until clean then a light coat of oil after every range session.

    I've shot over 1,000 rounds so far and just cleaned the gas cylinder for the first time.

    So a search for, "barrel break in" and you'll have more than you ever wanted to know.

    Remove rifle from package. Clean and lube properly. Repair to range with ammo. Fire rifle. Clean and lube properly. Repeat.

    There, that about covers it. If you really want to do a break in, I'd probably do 5-10 rounds of shoot-n-clean each round, then maybe 2-3 strings of 3-5 between shoot-n-clean.

    Honestly, I don't think it matters much at all. My current AR-15 match barrel is at about 1000 rounds and I didn't give it special treatment. Okay, perhaps I was a bit lax, as I did clean it with JB Bore paste last time, but otherwise, it's good to go.

    About the most telling thing is is that for the first 200-300 or so rounds, I'll make sure to clean the bore after every range trip, be it 20 or 100 rounds. After that, I don't fret so much.
