M1A vs. AR at 50 meters against concrete blocks. The M1A will be firing M80 FMJ while the AR is firing M855. In previous tests we looked at the effects of only a single round each and at very close range. This time we will put the AR against the M1A head to head, with as many rounds fired as are necessary to reduce the target to pieces too small to reasonably hit. Both shooters will attempt to fire their rifle as quickly as they can to make accurate hits. This is an informal test, of course, but we'll be looking to see which rifle can reduce the concrete "cover" to concealment more quickly and which can do it with less rounds fired as well as which uses a greater percentage of its available ammunition. Because 7.62x51mm weighs twice as much as 5.56x45mm, the M1A gets one 20 round magazine and the AR gets two. Which rifle do you think will win and on what grounds? Will the heavier recoil of the M1A allow the AR to finish more quickly? Will the greater mass of the .30 caliber crush the block with fewer rounds fired?
