i guess you could use an chamber adapter in a 308 barrel, maybe 303 or some other 30-cal.
If you just want to shoot 7.62X25 in an existing bolt rifle chambered in .308 or 30-06 you can get chamber adapters from this company. CHAMBER ADAPTERS

They would not work in a full sized semi-auto like a .308 AR other than as a manually operated AR since they don't generate enough gas pressure and gas volume to make the larger system work -- that's why I think they would be best in a bolt rifle. At one time or another I've seen cheaper ones available from Sportman's Guide but I can't remember what rifle or caliber they were designed for.
