Umarex Brodax Airsoft Conversion

My partner and I were walking through the local Academy on a whim, and I took a curious glance in the section full of airguns and airsoft guns. We both wanted an airsoft revolver at the time, as it seemed like a fun fidget, and we have some friends who are into airsoft who we'd love to play with, but wouldn't love to drop a lot of money on guns.

I spotted both the Elite Force H8R Revolver and the Umarex Brodax .44 Super Magnum, which seemed very strangely similar. The Brodax was half the price though. I purchased it, and began doing my research. First off, it's the same mechanism, the only difference it that it's chambered differently, and the H8R Revolver has a hop up.

The current version of my conversion kit does not have a hop up yet, but that may be an addition I add at a later time.

How to install this conversion

This is a pretty easy conversion to install, but you need to be pretty confident with your tools, and your ability using them. As a fair warning, this is pretty jank, but the final product is nice.

First off, choose your preferred tip. I went with a standard looking tip I could print out in orange. Regrettably I lost the link to the file, but I'm fairly confident you can find plenty just like it on a search for the airsoft gun, or the airgun on Thingiverse

Second, you want to get a length of ¼ inch KNS Brass Pipe. This is near perfect for a barrel. Print the rear collet, and install it. You may have to hammer it on, as I did. Be careful, as brass is a relatively soft metal, much softer than your hammer, so use light taps to gradually get the part on.

Next, put the barrel and tip in your Brodax, and mark the barrel where it sticks out the front. This gives you the ideal barrel length for your setup. I used a hacksaw to cut my barrel, with a drill and some sandpaper to finish the end of it, but you can use any number of tools, such as a rotary tool, an actual pipe cutter, or a lathe, if you have access to one.

You'll want to measure how much spring length is present at the front of your Brodax, as the next step is the retention spring collar for the front of the barrel. Doing some math, you should be able to figure out where the collar needs to be, though personally I just visually placed it, which seems to have worked out. You'll need to hammer this on too, but it can be very tricky, since this one goes all the way around the barrel. I personally used my orange tip as a buffer, so I could continue tapping it on.

Once it's all together, you should have an Umarex Brodax converted to an airsoft gun.

You're able to find H8R magazines printable on most 3D printable file sharing websites, but if you don't want to print your rotary mags, you can buy H8R magazines on Amazon, or likely from the Elite Force website.
