I just ordered a Parkwest Arms Dark Continent and am glad I did after looking at and handling a Rigby at Safari Outdoors in Johannesburg! The Rigby was not as well finished and was a lot more chunky in the grip, also the wood was fairly plain. Your paying for the name Rigby and it's not the same company as it was in the past. For the same money you can have a well optioned Parkwest and still have money left over for good optics! Plus if you need warranty work who do you send the rifle too, Parkwest arms is based in Sturgis SD!
Just my opinion, either way you will get a great rifle, but for $17,000 you will get a lot more rifle for your money with the Parkwest arms!
