Nah it is not a CNC programming error, the part wasn't put in the fixture straight. They may use the same machines for multiple product lines but the fixtures and tooling will be different because they are different dimensions.
I used to run a Fanuc 3-axis CNC machine at Ruger in their Prescott plant. I was the only guy in my group that actually owned a firearm. The rest were young hispanic immigrants, mostly.
We had to make changes fairly regularly to the programming to keep the parts in spec. And yes, placing parts in the fixture wrong was a factor.
On one machine where I was machining the dots for rear sights, the dots would suddenly be randomly off-center. It turned out to be a worn out fixture. It was for the P-series sights and had been in use for decades. Ruger decided not to repair it since the P-Series was being discontinued, anyway.
I dare say all of modern American manufacturing has fallen prey to "Corporatism" which is a philosophy of maximizing profits at the expense of quality and worker concern. It's sad and is destroying this country.
