To be perfectly honest, that's what took so long. It was materials, mold design, geometry...a bunch of things to minimize leveraged stresses. We also have a mechanical repeatability requirement that I'm fairly certain no other BUS manufacturer bothers with, and we had a few thousandths of excess lateral variability that we addressed, also.
If I had to put a number on it, given all the variabilities, I'd say pros are 25% better than MBUS when in the deployed position. When stowed, the rail of the firearm will fail before the sights for the pros. The range wheel is not a limiting factor on the pros in TOP durability tests. I'm sure that there could be issues where the wheel fails before the standard sight, but that amount of destructive force is outside the mil spec requirements, and although we generally test everything to failure, if something is performing well outside the specs with multiple drops, we may not get there.
