Well, once it was shipped, it got here from Indonesia in 3 days but it took awhile to get it ordered because of wierd email glitches and bad communications. All in all, it was about a 3 month wait.
The coaxial part of the rest will adjust about 6" above an official 100 yard br target box and go down below the sighter box about 5". Then there is the regular coarse adjustment under the coaxial unit that goes a long way. Just how far I haven't taken a real measurement but I was using it for 1000 yard testing the other day and it was set up for another gun and when I plopped down a different gun it was pointing way up in the sky over the target. Plus you have a little up/down movement on where you have the rear bag positioned.
The coaxil unit itself is sealed inside the main post and is not accessible but it does have four adjustment screws for friction. Last week, Uncle b shot off it with his 20+ pound 6br improved and it did need a little more friction than my 10.5 lb 6ppc but after I tweaked the two upper screws, it worked like a dream for him. I think he liked it by the grin on his face!
