Duane Wiebe is certainly no slouch as a Custom Rifle builder either. I liked what he had to say in his posts in that same Accurate Reloading forum link where D'Arcy Echols cited all of his reasons for farming out a lot of his work.
When either of those guys, or Rigby built a rifle on a Mauser barreled action, everyone knows up-front that the barreled action was a product of the Mauser factory in Germany. That's hardly the same as farming out work because a subcontracting gunsmith is too busy spending many hours on Doublegunshop forum bashing Donald Trump or posting crap data from the known anti-gunner Philip Alpers and GunPolicy.org
Another thing I noted from that AccurateReloading forum link was that Duane Wiebe has nothing but his website and contact information in his tagline, and D'Arcy Echols has nothing at all... no free advertising of any kind. And neither of them is hawking books or doing free advertising of overpriced gunsmithing seminars without duly compensating that forum's administrator.
I hope this comment doesn't elevate rocky mtn bill's blood pressure by much more than 200 points diastolic.
