There is a lot of sub models of the M77 Mark II. Not really understanding the boat paddle stock.
This will help narrow down the sub models:
Blued or Stainless finish?
Walnut or Laminated stock?
Target or Standard contour barrel?

A standard Model 77R Mark II - in fine condition- $475-$550.

Boat paddle was a zytel stock that had a unique shape and was a poor seller. After being discontinued they became popular and have developed somewhat of a cult following. They bring a good amount of money on their own.

They typically were sold on stainless rifles with sporter barrels.

Sorry I'll post picks. Its the all stainless version with the zytel stock pictured above.

Ok. Now I recognize it. Had no idea it was referred to as a boat paddle stock. Sure resembles one. Good info Cactus. Thanks for the explanation and picture sir.
