My original v1 Caliburn printed back when the blaster was just starting to take off. I later upgraded the ram, plunger and a couple other parts to v2 when the originals failed. Changes were internal and it still looks pretty much the same still. I've retired this blaster because it was a little too menacing for office Nerf.
The original v1 hardware was purchased from Captain Slug and the few parts for v2 conversion I found online mostly.
