A while back I posted to the prototype for a new pump action blaster.
The basic idea was to split up the spring and plunger into two different stacked tubes. This would shorten the blaster a few inches, and it would raise the height of the barrel. (It’s personal preference but I like the barrel to line up with the top of my shoulder. I think it makes aiming easier.)
Due to my crappy craftsmanship the best I could do with the plans I posted was this. It shot alright but the construction was really shoddy. It should also be noted that Hooongfu named the blaster the “Double Rainbow” in reference to a certain youtube video of course.
So I gave the Google SketchUp files to my buddy Andtheherois and he came up with these beauties.
So this weekend I went over and with Andtherherois’ help, we built another one for me. And by help, I mean he did most of the work while I would occasionally screwed something together.
Differing from Andtheherois’ versions, this one uses a polyester tube as a stock with a M14 rifle stock pad on the end. This stock ended up being quite lighter than Andtheherois’ fixed stock and more comfy than his folding stock. However, it was also much more difficult to mount, as polycarbonate pieces had to be cut out to fit in between the tubes.
Here it is among its contemporary pump action blasters. We have the rainbowpump rev 2 and a pumpsnap rev 2. Despite its longer draw the double rainbow is about 5” shorter than the rainbowpump and 2 inches shorter than the pumpsnap.
So I don’t really have a write up, but the following should help anyone with the right set of tools, skills, and persistence build the base blaster.
And that’s it. Questions, flames, and comments are all welcome. And thank you Carbon for the CPT, Split for the skirt seal, and Beaver, Stark, and Atomatron for the rainbow catch.
