| I just bought a EA lower with a DTI upper . What gr. or make of ammo sould I use to break it in? |

"Breaking in" the lower or the upper is really a non-issue. The type and material of your barrel would be the only concern. And even that is highly debated. Many would say "just shoot away", while others do follow a break in routine. Bushmaster wants about 100-200 rounds down a chrome-lined barrel before they consider it "broken in" . In any event, just use standard brass-cased 55gr FMJ and you'll be fine. IMHO. Others will comment with their thoughts as well. Just run it wet. Have fun and be safe.
