In case you didn't catch the title of this blog, today I'll be illustrating how to modify your Airsoft M4 buffer tube to allow you to install a MOSFET in your Airsoft M4. This tutorial is for M4 operators whose gun is wired to the back through the buffer tube, rather than wired to the front handguard like the other half of the Airsoft M4s out there.
The problem is that with the heavy gauged, silver-plated Mil-Spec wiring that I use, I have to sacrifice flexibility for improved electrical conductivity, which I'm fine with. So, it doesn't really make it feasible to just install the MOSFET and then just shove it into the buffer tube so that you can get the stock back on because the wire is not very flexible and I don't want to jeopardize having one or more of the wires come loose from the MOSFET. They are a huge PITA to deal with since they are just slightly too large for the screw clamp connectors that this MOSFET uses and if not connected properly, they will easily come loose which is an obviously less-than-optimal situation. After a bit of brainstorming, I came to the conclusion that if I just carved out a piece of that buffer tube so that I could connect it or disconnect it while it was still technically inside the tube, I would essentially have solved the problem at hand.
Here, you can see the result. Enough to access the MOSFET but not enough to jeopardize the structural integrity of the buffer tube and/or render it otherwise unusable with a stock mounted on it.
Then I cut that biyatch.
Here is the result. Boom.
