lurkingknight thanks so much for the response. I really appreciate your time. I guess my next question is what do I need to do to verify my age?? I turn 35 this year lol.
The breakdown on the motors was very helpful. So from what I can tell the versions of motor are more about fitting into the bodies of the guns as oppose to performance.
Another question I had revolved around FPS and distance. Is it safe to say that a G&G mp5 would shoot the same distance as their m4? I would venture a guess to say that their m4 might be a bit more accurate due to barrel length.
