I called Horton today and the automated voice said it would be 45 minutes. I made it 15 before deciding to go ahead and apply force. In my work-out area I have some of those jig saw like foam pad set up so I held the top in place and slammed the but against the ground. I figured if it is safe for my K11... Anyways, a few hits and it all came together. I'm actually pretty impressed with the quality. Nothing fancy, but nothing wiggles, bends, or appears in any way sloppy. The stock is solid. It came with two sight systems. A red dot and something I haven't quite figured out yet involving a rear peep sight and a fiber optic loop. I'm going to use the red dot, so won't spend much time investigating that right away.
Now for more threads about broadheads.
