While the Winchester-Cooey 71 and 710 rifles had some features of the Model 70 winchester, it is actually a different action.
The bolt is M70, but without the 3 position safety on it.
The trigger is also M70, but that is where it ends.
The M70 is a flat-bottomed action, the Winchester-Cooey offerings are round, like a [gasp] 700 Remington.
The Winchester-Cooey also has a recoil lug of the same type as a 700 Remington, but it is a bit thinner,
The safety is a two position type on the right side of the receiver.
They are generally fairly accurate rifles, but quite plain and utilitarian.
Most have stocks from Beech or some other non-walnut wood.
The 670 is the same as the M70, but not the 71/710 rifles.
