Like both M70s and M700s and slew of others. I agree there are less options for M70s. I do not think it has anything to do with CRF, theoretical perfectness of design of M70 vs M700s. There is not a lot of mauser options for stocks out there either except cheap junk. I think the simple answer why is the trends over the last 30 years where hyper-optimization has become popular: light weight and super accuracy (whether tactical, LR, or beanfield, etc...). The M70 does not have the reputation as being tops for any of these. The 700 and savage 100 do. Look how popular Tikkas have become and I see lots of new after market stuff for them. I'm sure M70s do well in the super classic wood/blue custom rifles, but those are few compared to others.
