You actually gamed it yet?
I had the WELL version. Stock it wasn't bad -accuracy shooting .28's was roughly equivalent to a stock long-gun AEG shooting 350-400-ish. It takes about $200 of parts to really turn it into a decent, and more importantly, consistent platform.
On the other hand, the BAR was fun, pure and simple. Even if it wasn't greatly accurate or anything, it was fun to play with.
