[QUOTE="NikatKimber, post: 1633667, member: 423"] OK, now that I'm not on my phone, let me expound a little. Yes, a .250" hole is a .250" hole... for the most part. But the $$ difference comes in here: is it a .253" hole, or a .251" hole, and is it that [I]consistently.[/I] Also, if the drawing says 2.750" from xyz location, is the actual location 2.751", or 2.755"? Precision costs $, higher precision costs $$$. The other factor in the part cost equation, is QC, how many parts out of a 1000 does the company inspect. And by inspect I don't mean "Oh, that one looks good..." I mean measuring every hole diameter, distance, and location; every measurement; every thread on the part. Now, as was mentioned, the lower doesn't have to be aircraft grade tolerances on all of it, which is why for the most part, cheaper lowers work just as well as more expensive lowers. [/QUOTE]
