AR15, M16, M4, Ruger Mini 14
The Ruger Mini-14 Ranch Rifle marked as .223 can safely fire the .223 AND the 5.56 NATO military cartridge. The Ruger Mini-14 TARGET model should only fire .223 ammo- no 5.56 mm
250-425 USD
If you are referring to a Sturm & Ruger Co. Mini-14, then the answer is that most were manufactured in .223 Remington. The Ruger factory has from time to time released the Mini-14 rifle in .222 Remington in limited numbers, most likely to satisfy limited markets (some countries do not allow sales of "military" calibers.)
Best left to a trained factory representative.
