Nope, can't install a regular aeg barrels onto the VSR because the hop up is different, the little notches on the barrel differ from AEG ones.
However, there is a relatively new item out at WGC and all those other places which is a new hop up assembly. This hop chamber takes regular AEG barrels instead of VSR specific ones. Its called the laylax air seal chamber or something.

dunno if its any good, but i hear a few people getting that and getting a 6.01 AEG barrel for it.
