I had a defiance before my Impact and the defiance was Smoother and tighter but the impact is faster. The defiance was DLC’d by the way.I really hadn't noticed this on mine but i've been running a tempest for so long that i'm used to forward pressure to close. Impact is a solid 2-lug it's smooth and i'm eager to see what it's like if i can get it broken in. Honestly i feel like the mass of that bolt plays a very large part in the perception of it's smoothness. The thing just seems to have much more momentum than any other action i've run. My personal tempest still reigns for me as the smoothest i've put hands on, but the impact is thus far my favorite 2-lug. And honestly while i was not terribly wild about my TL3, i love my little brothers origin. It's still kind of "loose" and needs to be run on axis but running his 308 is very fun with that action.
the impact has the right amount of slop IMO.
