M4's are FAR more reliable and sturdy than they are often given credit for.
Just to test a theory - I'm thinking I might just build a junk AR and beat the snot out of it, shoot the crap out of it, and never clean it - just to see how long it takes for something to go wrong. I think the results might be surprising. And from there - an actual quality unit would only mean that the results should be better!
I know SEVERAL BCM users who have carbines over 3K without a single cleaning yet.
It is plenty sturdy enbough of a system.
