Depending on the complexity of the checkering pattern, the complexity of the metal pieces (flush swivel studs, skeleton grip caps, etc) and whether I shape it from the blank, or send it out for a semi-inlet job... anywhere from 60 to 200 hours including all the inletting and a nice oil finish, plus sighting it in before delivery.
Hard question to answer.

Here are a couple in progress shots of another pre-64 with nicer wood and a full wrap checkering pattern.
I carve a few gunstocks... Here's a couple I made last fall. The first one is a laminated varmint stock on a Remington .222 Varmint rifle. It's made from birdseye maple, wild cherry and black walnut. The next one is a thumbhole stock on a Ruger 10/22, made from English walnut, sugar maple, and black walnut.
