It's not the adj OR HCR post, it's a different post in a totally different location.
If you look at 9071000's post, in the first pic you can see the original "vertical" location. Go up from there to the start of the C3 block, and you're at the original "standard" location, then it moves that forward again, making it possible to have a taller riser without shoving you back on the sled, and making the post just shy of vertical.
It's not the block that eliminates all the junk, it's the switch to the standard post.
FYI, as you move forward, you need less of a riser, so if you plan to do this, keep that in mind. Most guys seem to feel they need 1-1.5" less riser for a 2" move forward.
I really just wish there was a pic from the side, to see just how vertical that post is after the post forward.
ill try to remember to take a pic when I get home.
