no AEG fires 8mm, and the closest to an 8mm barrett is the old shell-loading smokey's monster.. (8mm, bolt action that ejected the shells that held a single 8mm bb)

bearing in mind that i was once shot across a small room in the back of the hand with that gun and i was only slightly pissed (wasn't wearing eye pro, it was marcus the retarded ex-gunsmith at wolf armouries.. they still have it iirc) rather then jumping around in pain, it's a poor choice unless you like spending a metric f*ck-ton on crap.

this (8mm AEG) is an interesting project but no-one will get it working as well as it could unless they craft a HOPUP unit that will fit the 8mm bb's, and even then it'll be hit-or-miss if it's actually usuable unless it's cranking a fair FPS (remember, the lightest 8mm i've seen is .34)

meh, better to grab one of the marushin 8mm m2 carbines (semi) and rock with that

I would hazard a guess (but it's out of my ass) that the larger bb would be better for longer ranges due to the extra weight (.45+ sure i've seen more) and due to the fact that air bubbles within the bb would have a lower affect on the HOP spin (more mass, less of an imbalence then the same size airbubble was in a .43 6mm bb V's and a 8mm .45)
