"Sporterizing" ("Bubbafication" as we call it today) was an "in" thing 40-50-60 years ago when milsurps were cheap, plentiful, and some people saw it as way to acquire a "sporting" rifle on the "cheap". Nowadays it is seen as a way of taking a $200 rifle, putting $300 into it and ending up with a $100 rifle.
Restoring an old warrior is a noble endeavor IMHO, while commercial sporting rifles are readily available, well designed and made and a better buy in the long run. Also remember many milsurps were used hard, often not that well cared for, reflect older steel and gun making technologies and in many cases accelerated wartime production. Just my $.02.
