The post war conversions are more interesting to me than an arsenal grade wartime rifle.
The 7.62 cartridge is cheap to shoot. The Spanish FR7 and FR8 have the best back sights of any Mauser - hands down. They are short and handy. I researched and chose to ignore all the internet blather about Spanish cartridges and small ring Mausers. Simply not trustworthy debates IMHO.
The Israeli rifles have circulated for probably three decades. They were the first big wave of modern cartridge Mausers, but every one I've seen has the wear and tear of a thousand recruits' handling and learning.
I considered but declined on the Chilean conversions, for two reasons. I don't like straight bolt handles, and I don't like the straight, no pistol grip swell style stocks. Other than these minor objections, they are extremely good rifles.
The Norwegians, Brazilians and Colombians (or Dominicans?) made Mausers in 30-06. No objections there either. If the rifle has a rear sight closer to your eyeball than in front of the breech ring, buy it!
