I'm the proud owner of a 187 series (thin barrel) Mini-14. It will never be sub-MOA and I'm fine with that. It's not an AR-15, and I'm fine with that too. I'm not worried about the accuracy or reliability of the Mini, since it has always performed for me. My only concern is this: what happens if I find myself in a fight requiring sustained high rates of fire? I've seen the guys on Guns and Ammo TV run a thousand or more rounds through an AR--as fast as they could pull the trigger--with no problem. If I empty one 20-round mag at a moderate rate, the barrel on my Mini gets hot enough to brand cattle. Could the Mini handle a firefight requiring more than a few shots without cooling down?
