If you look at just the rifle price it is a bit more (in the grand scheme of high priced rifles) as any other of the premier builders with premium action, stock, barrel, gunsmith work, etc.
I’m not talking Tikka actions, which are nice, but I’m talking top of the line $1400-$1600 actions, $1000 barrel, $1500 stock, bottom metal, trigger, etc.
Their value add is out of the box readiness (scope + assembly + data package to 1000 yards) and their ammo that is supposed to shoot well out of any of their rifles. Buying a rifle you buy into their system/guarantee.
Is it necessary? No. Can you do the same with a Ruger American? Yep. Even the Gunwerks owner has said so. But, you’re paying for just better quality and someone figuring it all out for you.
