I took my NRL hunter gun out of a KRG bravo and put it in the rokstok. I've put around 150 rounds through it in the rokstok, and I would say they perform nearly identically, but the rokstok is half the weight. Went from 11lbs 14oz with no bipod to 11lbs 6oz with a bipod. Suppressed 6.5cm, so it keeps you honest on recoil management if you want to spot shots well.
