ALL the 03's that came from the CMP in this current batch were returned from Greece. They were used to fight the communists, that's why the well used condition.
The best to get would be an 03A3 with a C-stock. After that a scant stock would be a 2nd choice. Since the CMP doesn't differentiate between a straight and a scant stock, it's luck of the draw. Also, for the most part, the scant stocks seem to come in better shape than the other 2 with the straight stocks being the worst of the 3. The sights take less of a scientist to use and you have a better sight radius. 2nd choice would be a Rem M1903, same stock choices above. As with the 03A3s, they are relatively newer and stand a better chance of being less beat up.
Of the 30 or so CMP rifles I've helped clean and inspect, none are anything other than shooter grade. Some original reciever-bbl combinations but nothing resembling an "original rifle. All except 1 were either worn metal refinish, US grey park refinish, or Greek blue refinish (what folks are calling the ugly black park). The 1 odd one is a low# SA that has a pre-WW1 US blued refinish.
The positive note on all was the barrels. The Greeks may have trashed the wood, but the barrels were all shiny and strong. A couple of the muzzles have been counter-bored a 1/4-1/2", but the bore is strong as death. There have been reports of of shot-out and corroded bores. In those cases the CMP was very accomodating and replaced the rifles in question.
The "cosmoline" the rifles are slathered with is actually #2 axle grease. Greece used grease..how ironic is that.
We had a contact at a local car dealership and used their parts washer to clean the rifles. Boiling water, Simple Green and gasoline (not recommended) are other cleaning methods suggested. If you have enough clout in your house, Simple Green in the bathtub or one of those big plastic storage containers is probably the easiest method for a 1 or 2 rifle cleaning.
In short, don't expect a collector but you'll probably get a good shooter. Expect to use a lot of elbow grease to remove the grease from Greece.
