Firstly, i LOVE shell ejectors, it doesn't get much more realistic than that. Problem is, as far as im aware, no company makes shell ejecting guns where the shells are designed to be LEFT ON THE FIELD, just like the BBs. I mean, whats the point of having the ultra realism of a shell ejector if you have to then stoop and gather your rather expensive shells?Think about it, the shells only need to stand up to being loaded into the mag, fired and then ejected once i.e. they don't need to be particularly strong/long lasting. I cant imagine real arms manufactures spend much more making shell casing than we spend on BBs. What does the internet think?
