The rifle is an older G model with a blind magazine, mid-late 90s probably. It's chambered in 270 and looks to be all factory. If I buy it my plan is to convert it to 6.5 Creedmor or 308, so I'm wondering other than a barrel what other parts might need to be replaced? Found it at LGS for $299.99 (fair price?). Thanks for any info you can provide.
