The one on top is mine; I am calling it the Violet Offender. The green one is my son's, and I just gave the red one to my brother for his birthday. It seems to have been a big hit, BUT, these ended up having a little more power than I had originally expected, to the point of being actually a little dangerous. I changed them from having an 8# spring down to a 5# spring, which was better, but we still need to go lighter than that. I tried to chronograph mine briefly but I couldn't get the chrony to pick up the dart. From what I have seen on YouTube, 200+ FPS is common, and some builders have managed to get over 300 out of theirs.
One thing that was kind of funny over at my brothers place, with all the kids that were there (mine, his, and his brother in law's bunch), it didn't take long before one of the kids figured out that the half length darts that the Lynx takes can also be fired by a standard nerf blaster, which will yield a significant velocity increase due to the lighter weight.
