Got my Tippmann M4 couple of weeks ago from Jason at Incentive Designs. It had a few extras put on it from new the incentive designs superbolt plus their new hop unit and a different nozzle and the awesome venom from Incentive Designs it's also running on hpa. I used it for the time at Bush Valley last Sunday and I'm in love. It sounds like no other gun out there the thing is a beast you can actually see foliage falling when it's firing on full auto. Going to get a new rail for it and fit a madbull barrel and Magpal stock but I'm seriously impressed.
