Asking the question again implies you are not happy others are not telling you what you want to hear.At some point, there is a price point that become absurd. To create a prosthetic knee, it costs us about 400-600$, which includes materials and labor. This knee has some insane tolerances and is top tier material. I can understand where people are coming from with buying quality gear, but is that laser, red dot, scope, or trigger mod really worth 500-900?
So your company could make pot metal knee for $50? They could make a literal killing on Amazon.
Do you think a quality optic is not built to insane tolerance?
