Reading this thread reminds me of the difference between mass production and hand craftsmanship. What charles kieffner says presumably applies to the former, and what Rkesp Tim souk say sounds more like the latter. Souk will have time to hand fit his parts, test each one, fit them again, etc, for however long it takes. Compare to making frames for Ruger or whoever, each frame can get no more than X minutes of operator time before the company starts losing money. The little parts might get Y seconds.
