At the moment I have a now broken electric rifle and a GBB Glock replica I always much preferred the feel of the gas power so I felt it would be better to go full gas rather than having to worry about gas AND electric. I live in a place in cumbria which rarely exceeds 20 degrees so I always ran black gas worked for me however high pressure does put some guns off..
I'm aware of the tinkering needed to get the GBB up and running through my pistol but it was more a I don't want something which I'm going to need to buy lots of replacements for and be in good condition overall
I also have just seemed to be fully unlucky with every aeg I've ever used in it consistently arriving DOA or dying very quickly with some form of electrical problem
