Tired of failure to eject Watch this

I am blown away by great examples of engineering by amateurs and professionals alike who achieved perfect and reliable ejection of the shells in their gun creations. These are samples I have 1t hand experience with and the ones I discovered by searching the web, YouTube. The most interesting is that simple blowback designs without extractors and with or even without ejectors work pretty well. I cite the videos by others and give them full credit and respect. Enjoy and learn as I did. If possible, leave me links to other creations that reflect this idea of simplicity. I want to file those away for a future reference. Tnanks.
