I notice some AR's list the barrel as Wylde and will shoot .223/5.56. Most notably Rock River Arms. I'm looking at purchasing a DDM4 v2 or v5 once I get my restricted back but would like to know it can run both. I've searched but can't find any proof one way or the other. Can someone drop some science on me? Is there a benefit or problem in running an AR that will run both over one that will only run one or the other?
Thanks,
