Company that makes nice monopods that I know of is Accu-Shot.

About the LiPos - I know about those batteries, I've considered it, but since my SCAR is currently running 535 fps, my battery needs to be a bit bigger
But there's no problem for me to make some sort of hole in the stock if someone in the future would like to put a small lipo there.
First, the side view:
Now let me explain myself :P I've modeled the stock after this photo:
http://3.bp.blogspot.com/_eRPHqoaA9g...0/SSR_2010.JPG with obvious changes to the design required to keep the rigidity when 3d printing (I kept the cutout from the original MK20 stock and changed the bottom of the stock where the rail is). I've just resized this photo on my screen so that the dimensions fitted my SCAR and took measurements off the screen
For the mounting plate I measured and copied the mounting solution from the standard stock. On my screen the stock is around 200mm long, my stock is exacly 195.5 mm long, so thats about right. Height of the mounting side cannot be altered - it's exacly as high as the standard one, 81.8 mm. Maximum height of the stock (top to bottom) is 121.4 mm. On the photo its around 120 cm, depending on how you look on it. I think it's quite correct, but I don't say it's 100% correct - it never will be unless I get my hands on the real one :P
