I actually did this modification about a month ago but never got around to posting it. The mods are very basic and shouldn't need a writeup but I figured it might be helpful to someone newer to the hobby. So anway on to it...

First remove the ammo holder and priming handle. If you can't just rip off the handle use the back of a hammer. Then take out the screws.

What you should see now:

Now pull out the plunger rod, and carefully Zap-A-Gap some foam into the plunger head seal(I used part of the back of a BBB arrow). This expands it increasing the seal. Then lube it.

Posted Image

After that pull out this metal pin in the plunger tube.

Then widen the airflow. I don't remember the exact size drill bit I used but make sure the hole is no larger then the I.D. of cpvc.

Posted Image

Now put the pin back in and Zap-A-Gap the little holes. This makes it airtight.

I found that wrapping E-tape around the hole in the barrel still let air escape. So instead I lubed up a piece of cpvc, put it in the barrel pushing up against the hole, and put hot glue on the hole. This made sure no air leaked their anymore.

A short video showing what I am talking about:

For the barrel I wrapped about 1.5 layers of duct tape around some cpvc. I found that this made it perfectly tight in the stock barrel to be used like a coupler. It is suprisingly airtight. The E-tape is just for a better grip. You could make it a speedloader if you wanted to.

Now all you have to do is put it back together and your done!

Range test vid:

There was no wind and ranges were taken with slug darts and were shot flat. They were shot into grass so there was no dart skip.

Results: 58' flat, 62'flat

Conclusion:
Overall I am fairly pleased with the end product. 60 feet flat is pretty decent for an Eagle Eye. Especially considering that I didn't add any springs, and how easy this was to do. It is still too big to be a sidearm so there isn't much use for it, but it was just a nice fun side project.

If I am not mistaken, a barrel replaced eagle eye has already been done. But anyway, very nice work on the job I guess.

This is a nicely done writeup, but wrapping a barrel in tape to fit in mega barrels and gluing a hole is not worth it.

He also widened the hole for more air to escape faster. I think he did a good job. Sure, it might not go to the directory, but still.

1. It has been done before but I haven't seen any couplered before.
2. Thanks!

Are you talking about the writeup or the modification? If it is about the modification I think it is definatly worth it. I only had to do a few things to get good ranges, which is great. If you are talking about the writeup I would have normally agreed. I myself was even wondering if it was worth making a writeup for such simple mods. However the current Eagle Eye mods in the directory didn't do several of the things I did(Most importantly the airflow and coupler part), even if they are extremely simple. So I figured it couldn't hurt to do a writeup.

I was referring to the writeup, one of my very first "mods" was wrapping a piece of acrylic in painters tape on one end and making barrels for a ssii and eagle eye, it's something you can do to any maxforce mega blaster, and I think all of the cyberstryke ones as well. I wouldn't call a barrel wrapped in tape couplered.

True, I just called it "couplered" because it worked the same way and was just as effective as a normal coupler. I was going to put a normal coupler on it first, but found this to work just as well, and much easier to do.

If you repeatedly push it in and pull it out like that you may leave disgusting black residue on the inside, especially during the summer. Imo a real coupler is more effective in the long run.

The tape doesn't seem to get worn down at all, and even if it started to it would be very simple to replace before it became sticky. However I do agree that a normal coupler would be better, its just that it isn't worth it for this kind of blaster. Plus I did this just as a quick fun mod to take a break from my complicated mods.
