IBS VFS stock info

[Kitestir]

I have a straight stock on my BR gun. I would like to make it IBS VFS legal. Is there a diagram that shows the required slope etc? I have looked at IBS rule and would to find a diagram that shows the dimensions etc. I have searched for pics with no luck.
Thx

"having a toe formed by a straight line drawn from the toe of substantially vertical butt with a 13-1/4” pull starting at a point at least 4 inches below the axis of the bore and extending forward to the centerline of the barrel at a point no more than 18 inches forward of the Bolt face a barrel not less than 18 inches long"

This is the rule description. Lay your gun on it's side on a table and use a cleaning rod to simulate the "bore axis", and make the measurements.

Thanks for the pic. What rule book is that? In the IBS for score rule book it doesn’t show that diagram. Is there a link to it?

That diagram is actually from the NBRSA rule book, but the verbiage is the same between both organizations. Follow below and it’s on page 34 of the pdf file.

Very interesting. Much simpler to visualize with a diagram. Thanks for sharing.

Measure some stocks, not many are made with as little taper as shown. Plus, there isn't anything said about the forend, though most are tapered too.
