Airsoft M4 Dummy Mag

I was inspired by this design https://www.thingiverse.com/thing:6334311 for the AK-series, however, I could not find a similar one for the M-series, so I made my own version. This thing is still in development and testing. I'll add a few more options later if everything goes well. UPD After several tests, I found the following: on some manufacturers, the 100% scale fits very tightly and is very difficult to remove. When printing 99% of the scale, the situation is better, but there may be a slight backlash, which is acceptable for dummy mag. You can experiment with the scale, but I recommend printing 99/99.5%
