b) Have a QC fallout rate of over 30%
c) Consistently deliver late, and
d) Always go over the job quote by at least 20%
And if you did all of those things, every time... you would have a shitty shop, but if you provided your standards and procedures to your customers, your employees knew the company standards, you ran a safe shop, documented your poor workmanship, and complied with OSHA and EPA regulations, you could - in theory - have an ISO Certified shitty shop.
If I made barrels from the highest quality, 2.25" 4150 CVM Ordnance steel, following the the TDP print to absolute ideal tolerance, they technically can not be called "milspec" cause MIL-B-11595E calls for barstock, ordnance steel, under two inched in diameter.
Milspec, mil standard, etc, etc mean nothing in and of themselves... other than there is a standard; it is incumbent on the customer to understand what the standard really is... as I've said before, if you don't believe me try taken some toilet paper home from the BEQ and give it to HH6; see how far telling her "but it's milspec T.P. hun" gets you... big difference between issue "John Wayne asswipe" and oh so fluffy Mega Soft Angel Cloud bathroom tissue.
I can look... but I am pretty sure there not a requirement for forging details mating.. it is a cosmetic issue...
That said, I am not saying it is not important - one company I worked with for a while actually milled the little forging "bump" off of the upper receivers and radiused the top of the forging bump on the lower, so it ended before it reached the mating line between the two - and they did that solely to make their upper an lower combos look better - I like that attention to detail, but also recognize that it really means nothing as far as the function of the gun.
