Hey,
I am in no way an expert but I figured my oppinion might be helpful. I've done a bit of research on the aeg's because i just purchased one myself. I went with the ICS. My decision had a lot to do with the organization of the upper and lower gearboxes. The upper is designed to be interchangable (a major point for me because later on i plan to upgrade and keep a stock one for indoor). Another selling point for me was the forward assist. I like the idea of perserving my spring and piston, so it was a real plus. The ICS m4 is also designed by a reputable company. I did a little research on Olympic Arms, and they have been one of the leading companies in m4 research and design.
It is a rock solid gun. Very accurate once you adjust the hop-up and zero the sights.
one problem i hear they have is an extremely weak motor.. now mine is still stock, so im not having problems but that is one thing to consider

IMO the ICS m4 is the way to go

No, no, no! You gotta shoot someone then divide how loud he screams by the distance from the muzzle! :twisted:

Yep and then you have to Determine if that was an ARGGGGGHHHH or a WAAAARGGGGGHHHHHH!!!!! There is about 75fps of difference between the two. :lol:

not to mention how fast they double over... but thats only for guns over 300fps...

on a more serious note...
would it be acceptable to upgrade an m4 to around 500 fps and only opperate it in semi auto mode? as long as its more than 50'

also... with the same m4 upgraded to 500 fps... would a bb break of some sort...(i've seen them out.. the correct terminology is slipping my mind) that could slow the bb down enough enable it for full auto feild play be acceptable?
