I owned a M70 of 2018-2019 vintage.
Overall assessment: an attractive gun, built on a solid receiver, with a so-so bolt, and a scrap tier barrel.
The good:
- Action itself was "true" per WGW, no additional work required there
- Bluing was applied evenly, not prone to rust in either North Carolina or south Georgia
- Quite an attractive rifle (mine was a Supergrade Maple)
The mediocre:
- Factory "hot glue gun" style bedding is better than nothing, but done with cost saving rather than quality in mind
- MOA trigger is just "OK," limited aftermarket options (a pre-64 this is not, in that sense)
- Only one bolt lug in contact, required lapping (which I did, wasn't a huge deal)
- The bolt was loosey-goosey, not nearly as smooth as a Tikka costing roughly half as much
The bad:
- The extractor was out of spec, required filing/grinding to address function issues (bought a spare just in case)
- Mine had only a 3.4" mag box (.30-06), but if you buy a magnum, you should be G2G (understand those are 3.6" iirc)
- The factory barrel was good for an average of 1.5-2 MOA depending on the ammo - simply atrocious**
**I first bedded this rifle properly. Didn't help. Swapped in a Timney, didn't help. Swapped into a McMillan stock, didn't help. Bedded that stock as well, no bueno. Had WGW install a Bartlein CF barrel - group average magically shrunk to about .65 MOA (for 5 shots) with factory Hornady 150 and 165 SST and Norma 180 Bondstrike and hand loads. Sadly, after changing the stock and the barrel, everything about the rifle I liked was dead... the mag length restriction was just the final nail in the coffin for me.
