This question goes out to the experienced, armorers etc.

We all know about upper & lower play. This topic has been beat to death in regards to accuracy, remedies all of that.

I have searched without result here.

What I'm curious about, is at what point does this become excessive? Has anyone ever had such a large amount of slop that the rifle will not function? Is this "problem" self limiting?

Read the US MIL tech manual. It talks about this and using a .020 feeler gage.
