Here's a new year's present for 
@SDHNTR, 
@Frank Dux, 
@JBMAK, 
@Alwaysworking, 
@WKR, and anyone else who has questions about the design of this stock, but is not wanting to read the whole thread:
The following link will take you to a list of *just* posts by 
@Formidilosus in this current (Rokstok) thread: 
https://rokslide.com/forums/search/...ead]=329754&c[users]=Formidilosus&o=relevance
And for anyone who didn't know how to do this before (I didn't until I just tested it), go into any thread, leave the search term blank, select 'This thread' from the drop-down next to the blank search box, and choose the username whose posts you want to see. That will bring up anything by a particular poster in a dedicated thread.
Hopefully, this will reduce the number of posts asking questions that have already been answered, and then myself, 
@Reburn, 
@BBob, 
@fwafwow, Form, 
@Unknown Munitions, 
@ljalberta, and others saying 'read the thread/listen to the podcast' (and then getting reported when we do ... 

).
You're welcome!
