The Impulse and the BKO don't even compare. The Impulse is faster, more consistant and uses it's solinoid to both push forward and pull back, unlike the BKO which uses a spring instead of pulling back, thus making it less consistant. The Impulse also comes with the Max Flow regulator system, and a progressive barrel. That and basically everything on the impulse can be upgraded if you want.
