Sorry that my original question was a bit vague. Damn wireless keyboard misses some of my keystrokes and makes look drunk if I don't proof read my posts.

So I was wondering if MEGA's uppers have m4 feed cuts... from your answers I see that some do and some don't... Thank you for answering this. Now I must ask.... Where can one purchase MEGA uppers with m4 cuts?

Although I really don't feel they are very important, I really want to make this build one that I'm patient with getting the exact parts I want and I have my eye on a barrel that has m4 ramps.... just threw that in there so we didn't begin discussing the pros/cons/usefulness of m4 feed ramps.

If your question is: Do stripped uppers manufactured by Mega Machine Company have anodized M4 feed cuts?

The answer is maybe.  They manufacture them both ways.

some do, some dont

depends if you buy them with or with out m4 feed ramps.  dont cut them yourself they are not that important

This is where I got my Mega receivers with M4 cuts -
