Cougar, the riser block came from Binghams. It's what they call their Coreflex/Superaction Riser Block. It measured 1-1/2" x 2-1/2" x 17". I used the full 17". The form is a copy of Steve Turay's Nothern Mist Baraga. I personally think the Baraga is a fantastic design for a LB.
Again, thanks to all for the nice comments. I hope the thread was informative and entertaining.
Now that I'm hunting with it, I can't find a deer anywhere. You would think they all left the county for parts unknown, EVEN WITH THE RUT ON!!
