High-Capacity Mod for the Nerf Praxis Magazine
This mod guid will show you how to transform your 10 disc magazine into a 27 disc high-capacity mag. Even though it holds 27 discs, the magazine is barely longer than a Stampede clip.
First, unscrew your magazine and remove the bottom cap and the lower spring seat. Using a Dremal sanding drum, dremal down all the guiding bars and the protruding edge up 1/4″ into the magazine. Do this to both sides. Next, Dremal the three guide bars on the disc pusher completely off, and round off the bottom edge with sand paper. Sorry theres not very many pictures, I forgot to take them during the modding process, but I will do my best to explain in detail. Now, you will need an 8″ section of a fluorescent tube protector, and an end cap for it.(these tubes can be bought at any home improvement store, they also come with end-caps)
Using a Dremal sanding drum, sand a 25 degree angle slant all along the inside edge. This will allow the discs to be loaded smoothly. Set this aside for now.
Unravel the wire binding from a cheap notebook, and smooth it out. Take a 36″ piece of 1/2″ pvc and Dremal a slit at one end. Bend the end of the wire into a small L-shape, and slid the wire into the slit. Wrap the wire around the pipe, with about 1/4″ of space between the coils. My spring is pretty messy, but hey, it works.
Drill a small hole where the coil ends, and push the end of the wire into it. This will keep the spring from unraveling.
You can now remove the spring from the pipe. Pre-heat an oven to five hundred degrees, and bake the spring for an hour. (get your parents permission)
Finally, take the fluorescent tube sleeve that you fabricated earlier, and apply hot glue around the top of the pipe. Do this only to the top portion.(about 1/2″ down from the side you dremaled to a slant) Push this end into the bottom of the magazine, making sure to keep it straight while the glue cools. Next layer a good amount of hot glue over the join.
Take your new spring and duct-tape it to the original one, bottom to top.
Drop the disc pusher into the bottom of the pipe, making sure to put it in the right way.(the side with the cut out should face up when you look down the top of the magazine)
Next drop the spring into the pipe and put on the pipe cap.
If all went well the magazine should be able to hold around 27 discs.
