Not trying to turn this into a pi$$in' match and I understand everyone likes what they like. I own 3 CZ rifles, all of them NIB (when I got them) two are CZ 550 FS rifles in 6.5x55 and 9.3x62. The other is a CZ 527 in .223. They are very nice rifles and are quality made firearms in today's marketplace. Their fit, finish and bolt smoothness cannot compare with the M70 IMO, especially the pre '64 version. Both my CZs are good enough shooters with the medium bore outshooting the 6.5 believe it or not and giving sub MOA groups. Bolt smoothness, however, is not even close to a CRF M70, even a newer version. I also owned an early Kimber 84M in .308(NIB). It was never what I'd call a great shooter, but shot well enough. It's fit, finish and bolt smoothness were not as good as an older M70 Featherweight Classic I also own(7/08). It moved out eventually, allowing me to buy one of the CZs. Not a thing wrong with any of the rifles I mentioned and I'm simply relaying my personal experience in owning them.
There are a LOT of quality manufactured older rifles out there produced by Mauser, Husqvarna, FNH, Winchester, Browning, Sako, etc that will last two more lifetimes, even being 50+ yrs old now. I'd simply recommend shooters and hunters take the time to examine some of these fine older bolt rifles, assembled back when workmanship was formost on makers' minds and accomplished in a manner that simply cannot be done today at under 2 grand, IMHO. I also own a good number of Ruger and Remington rifles, etc., which I like, or wouldn't own. They do not impress me near as much, however, as the older finely made bolt rifles I happen to own from years past.
