Well we’re changing that.
Primary Project Goal (Achieved):
Develop a homemade plunger system for the Recon achieving intermediate range while still allowing full use of the stock blaster’s features (clip loading, attachments, etc.) and keeping most of the new internals inside the gun and maintaining compactness of the blaster.
Secondary Project Goals (In Progress):
Design the modifications/homemade parts so that anyone who is able to build a +bow can recreate the ReconBow. Also, modify the existing attachments and make new accessories to make the Recon a more useful blaster.
So I wanted a Recon (I like the Recons shell) that had an internals replacement, but not some stupid AirTech integrated into it. I wanted a springer that could use an Angel Breech to achieve pretty good ranges while keeping the ROF of the stock blaster.
I was oringinally going to leave the catch mechanism in place, but the performance would have been worse than a NiteFinder’s. The new plunger tube is about the diameter of a NiteFinder’s, but hopefully by making it slightly longer I can achieve ranges of about 100 ft. Since I moved the catch though, I had to design a completely new one. Thanks to CS for designing the +bow catch which the ReconBow catch is based off of. Since it is made out of plastic sheeting, you will need to download the cutting templates
Also, I want to say that I designed this mod to allow for rushing while using a Raider drum while still getting shots off at more than 50 feet. +bow ranges were not necessary for this project, just good enough to hit close range targets accurately.
You do not need everything on this list! I had most of the stuff lying around so this is what I chose to use. Please read through the writeup and see what you need before buying all this stuff.

I’m pretty sure I used every tool in my shop (which is a lot). You don’t need to though.
The writeup will be broken into two parts: One for everything dealing with the plunger/ catch, and the other one dealing with the barrel/breech. Since I went through design changes so many times the parts list/writeup may not be complete/coherent. The next time I make one I will post a better writeup. Therefore, DO NOT follow this writeup word-for-word. Use your head.
Dremel out the back of the shell to fit the catch mechanism like so.
Cut out your plunger tube to fit right up against the clip, going most of the way back. You will have to trim it later.
Cut out all the template pieces (besides the circles) out of 1/4” polycarbonate. Drill the holes before you make the cuts. Also tap the holes that need to be tapped. (These templates are different from the ones you’ll be making).
Now you will have to make them fit the shell by beveling the corners and maybe thinning them out. Make sure everything can fit smoothly. Don’t forget to file the edge on the catch plate to make it slide easier.
Now put the catch mechanism together, and then cut the plunger tube where shown. This will be where the trigger will fit. In the picture, the spacers are on wrong. Put them between the frame piece and the catch.
Now cut and drill/tap the plunger rod from a 3/8” PVC bar. It should go from the front of the plunger tube and stick out the back a little bit.
Then make the plunger head by using a 3/4” washer, 1 1/6” by 1/16” rubber washer (don’t use the one in the parts list, it’s too thick. I got mine at Home Depot), and a 7/8” washer on top.
Now we need to make two plastic rings. I don’t like cutting circles so I got 1” plastic (PVC) rod and sliced off one 1/4” piece and one 3/16” piece. Then I put the circle templates on the rings. You could of course cut these out of regular polycarb sheets…
Then drill a 5/32” hole in the center. Since the plastic was too large, I put it in my drill press and lathed down the O.D. until it fit in the plunger tube.
