M70 G-serial # Receiver footprint

Have a nice stock with a M70 G-serial number push feed 30-06 in it.

Guessing this rifle was built in the mid-80's.

Would like to use the stock, but put in a controlled round feed receiver with a good barrel.

Are there any controlled round feed M70 receivers have the same external dimensions/footprint as the G-series?

Thanks.

The "G" serial prefix merely indicates a generic Model 70 and can apply to either push or controlled round feed; 1968 or later rifles. The earliest POST 1964 CRF Winchesters were from the 1991-92 era and subsequent.
I can't comment about receiver swapping other than to speculate 'a problem' and result likely jury-rigged. The barrels would not interchange on the actions without significant work, if that's what you were intending. If swapping barreled actions, the barrel profiles would likely be different and either significant channel work or glass bedding to accommodate gaps. There are also matters as bolt handle cuts as well as bottom metal configurations. The short answer, 'possible but impractical'. Aesthetics and resulting market value likely suffering!
By the time you acquire a CRF rifle, presumably cannibalize it; end up with a mismatched push feed & CRF stock; likely better investment just to buy a nice CRF rifle and be happy with two ORIGINALS!
My early nineties off the shelf 70 Super Grade, 338 Win Mag, with a handsomely figured stock, paralleling the 'custom level' pre-'64 SG.
My take

It will fit any long action Classic with the same barrel contour and two piece bottom metal.

Thank you both.

W70, great info, exactly what I needed to know.

It currently has Blackburn bottom metal and I am thinking of ordering a Krieger to match the current contour, which is the basic factory contour.

I swapped out a M70 338 WM push-feed barreled action from the mid 1980's and put a 2005 era M70 338 WM CRF barreled action in it's place. My rifle needed a little glass to make it fit perfectly but it was only the variation in depth - barrel channel and action dimensions were the same.

Great info Odessa, thank you.
