HS Precision is more precisely made. The Bell and Carlson stock bedding block needs bedded generally.

The last B and C stock had the bedding block so tilted that you couldn’t start the action screws without the screws touching the side of the bedding block. Easy fix but if you don’t like obstacles you are better off going with HS. The few that I have worked with have been fairly square.

I will continue to buy B and C stocks, however. Good value and you end up with a great stock, if you don’t mind the bit of extra work.
