Do 7.62 AR10s really have a place anymore? A 6.5 is superior for external ballistics, even out of 14.5/16 barrels based on numbers I ran, and will have better hit probability in wind. Is there any reason other than perhaps barrel life to have one of these anymore?
A good use for them is burning up ball ammo if you have a stockpile. If I were in the market for just 1 ar10, it would be the cm.
