We at Sights and Arms love our Pristine actions. The interchangeable bolt heads allow our customers to use the same Action with multiple calibers which is fantastic. And I can't stress enough the smoothness of this Action! That bolt rolls up and out like it was made of half-melted ice. After cycling a Pristine, I wouldn't want to go back. On top of that, every action we've received from them has been top-notch in terms of quality control. Never had any issues with any of them out of the box and they're a company that really stands behind their quality. Keep up the good work and excellent customer service.
