I’ve been dealing with these guys for the last 6 or so years and they’ve taken great care of me. My first rifle was a Priest and I emailed them to know what I needed to upgrade it to the next generation of Priest. They sold me the upgraded rear block with no questions asked. After that they upgraded my adjustable regulator with no questions asked. Now they have sent me, at no charge, all of the guts for that regulator to upgrade it to the newest generation. Can’t beat all of that for customer service.
