Black Impulse w/ brass hammer, after market delrin bolt, W.A.S equalizer board, clampind feed neck, smart grip, and after marker blade trigger.
Fastest board you can buy, unlimited rate of fire, anti chop eyes, and looks cool.
I just bought my impulse about a month ago and my gun nevers chops. I have not choped once with the equilizer board. There is no reason to get a vision eye because they cap of at 20bps, the eqiulizer has unlimited rate of fire, and they are about the same price.
This is the best board you can get for an impulse!!!!
