Please forgive me for always playing Devil's advocate, but how in the world do you know this? I mean, you say it like it is absolutely 100% true.
I've been buying and shooting guns for years. I buy lots of stuff from various manufacturers to accompany my guns, but I have no idea how much time ANY of the companies that made my guns, components for my guns, etc., spent in R&D. I have no idea how detailed their QA/QC is.
But you talk about it like you have first-hand knowledge and what you say is absolutely true.
Is this another assumption?
And get this, I only play Devil's advocate because so many people say things that they act are true yet I'm not sure how they got their information. Uno, you do this constantly. I mean, do you spend time with all these manufacturers and watch over their operations, or are you just guessing?
