I’m not a machinist but I’ve always heard the mag blocks are better quality.
Has production machining equipment not gotten better and/or more accurate in the last 30 years? Serious question because In the industry I’m in, the cnc machines are light years better than they were even 10-15 years ago. I have 3 multi million dollar cnc machines (for structural steel) that are 8 years old and damn near obsolete at this point.
