So far I have found 223(5.56), 243, 260, 6.5, 6.8, 308(7.62) offerings in the AR rifles.

also 9mm, .45 ACP, and .50 cal.(handgun .50 not the military round)

I think also there's a 45-70 based bullet something like a 405 -407?? I guess if you want to shoot buffalo with an AR!

i gess if you want your sholder to hurt for a week after shooting it. AR's are realy light so no real recoil reduction.
