I love the fact that you guys are lecturing one of the few individuals who has found a way to be successful in the custom gunmaking world on his business practices. There is little chance that the cost of changing the barrel twist could be offset by five guys on this board who would buy a rifle because it had a faster twist. He is, after all, running a business.
For the record, and from the horse's mouth, Barrett used a 1-7" twist on the Fieldcraft because they were already making those barrels for the REC7 (the piston version, not the current direct-impingement carbine). It was, HINT, a business decision.

Changing twist rates is no big deal at our barrel shop.
