I was recently admiring the work of PointBlank's "Cyclops" mod and how he managed to get an Airtech 3000 tank inside a nightfinder shell. However I wasn't so pleased with the idea of removing the perfectly good internals of my nightfinder, so I came up with a way to have both guns functionally in one gun. This is a VERY similar mod however we externally mount the pump.

The first part is not pictured, but you're going to want to take your AT3K tank and strip it completely clean of all flanges and extremities.

The you're going to take the housing of your light, remove all the wires and the light, but keep the housing. cut the flange off of the bottom so it will sit flat. Attach your barrel material inside the light and glue the whole thing to the front end of the tank like so:

Keep in mind however that when your tank and barrel assembly are inserted your pump valve is going to need to come out the side, so plan how you glue them all together.

Then you're going to need to drill a hole in the side of the gun where your pump valve will come out of.

Also, you're going to want to drill out and remove all screw posts from where the light used to be so the tank can fit. Then you're going to cut out the front enough for the tank to fit through the front. Its so unfortunate that it wont fit by such a small distance.

Posted Image

Then we need to move on to the Nightfinder internals. You can do any of the basic mods you choose. I chose to attach the CPVC barrel inside the internal coupler from the plunger tube and the stock barrel like this:

I then put an ACE #49 spring on the plunger and put some Teflon tape underneath the o-ring for a better seal.

Posted Image

Then I filed down the barrel tip so the CPVC will fit through:

Now to the AT3K trigger system. For this I did a linked trigger so I can fire both shots at the same time or still have the option of cock-shoot-cock-shoot. For this I bent the tank pin in a full circle:

Posted Image

Now be VERY careful when you do this, use 2 pares of pliers, one to hold the pin and one to bend it. If you just try and bend the pin you could break the plastic on the tank and create a fatal leak.

Next we're going to drill a hole in the trigger in the rear for out new trigger wire.

Posted Image

I didn''t get a picture of it, but I used a section of wire hanger between the trigger and the firing pin and ran it underneath the original trigger.

I also drilled some holes through the trigger for some extra style points and attached the brass end of a 12 gauge Remington shot gun shell to the pump as a pump handle. Its very comfortable.

Posted Image

This photo was taken after painting it, but I've attached the pump to the left side next to the light with epoxy putty. I advise nothing less than epoxy putty. My first attempt with liquid epoxy failed to hold through a small indoor battle and hose clamps just let it slide though, so use plenty of epoxy putty.

Posted Image

Now you can put it all back together, with your AT3K internals AND your NF internals. I ran the hose underneath the front of the trigger guard, through the gap under the barrel and into the side where the tank is. I sprayed mine with a candy apple red metallic paintjob. And I give you the "Blood Finder".

This is really nice. I like the way you kept the night finder functional as well as the 3K. Also nice place to put the pump, props. I love it when someone finds good use for the space that war the light.

Just beastly, the candy paint and the black barrels are very nice. I also like how the brass shell part makes it look a titch Iron Man-y.
The Difference:
-Guns shoot bullets that kill people
-Blasters shoot darts that tag people

I do not play with guns.

I like it, its very clean and the paint job is pretty sweet. The shot gun shell for the pump is pretty excellent as well, is it hard to pump the gun with that though? It just seems like a small thing to hold on to, but I do have rather large hands.

No, not at all. Its about the size of an AT2K pump handle and I usually only do one pump anyways. And I have pretty big hands too.

When I read the post title I was ready for a "cyclops" carbon copy, but this is amazing.
I love it. The pump handle and placement is engenious. (sp?) As well as the trigger linking. You said in the write up you wanted the option of both shots at once or semi-auto. How could that be semi?

Mega props.

Well, I don't have it rigged right now to be semi but it is possible. Right now, one trigger pull fires them both at the exact same time, but if I where to trim the trigger a bit and tighten up the linkage, i could get the AT3K to fire on half a pull and the NF to fire on the whole pull thus being semi auto, but I liked it better this way. Right now, I pump it once, shoot a dart, then I cock it and shoot another.

This reminds me of NortherofHeavens integration... but I like this one more only because it looks "ballin" haha.

P.S. Is the movie Transformers?

I'm not even trying on the movie; that picture's just way too vague.

As to the gun though, nice work. I do like that you kept the nitefinder functionality wise, but the only reason I would still choose the cyclops over this is cleanliness. Yes, you did it cleanly, but it still has the pump stuck to the side. Something tells me that this is far less awkward to pump though than something like the Cyclops.

Hey...I got a crazy idea: how about you stop all that sigging stuff? It's not even my thread and it annoys me.

Very clean integration. The paint looks very nice. What paint did you use?

And is the movie I Am Legend?

It looks really nice. I like the paint job and the pump placement looks handy.

Great idea and gun.

I think the movie is X-Men:Last Stand (The part where they fight the sentinel).
