So my son has long forgotten about his Nerf guns so I took a shot at this prop replica. I gotta say, I was surprised at the amount of custom work it took to get the look right. Far from the "glue a couple parts together" that I had heard. And for you Terra Nova purists, I did take a few design liberties, but it seem there are a few models seen on the show, so I felt justified putting my unique spin on some details. Anyway, this was a fun build on the cheap. And with some weight added, it's a credible replica.
