I want an AXIS in .223 and here are my choices as of now: I can buy a used AXIS with a Sightron 4-12X AO scopefor $400.00 in 30-06 or a new AXIS in .223 which is the caliber I want for $319.00 OTD but I'd have to add a scope. I don't know what the conversion cost from 30-06 to .223 would be so which is the better way to go?
