You don't "need" M4 feed ramps, maybe if you're shooting full-auto a lot. With the .223/5.56 cartridges they aren't necessary for semi-autos. As far as your upper not being lubed, you should be inspecting and lubing your BCG yourself before you fire it anyway.

Dont worry about dry film lube. It isnt gonna matter or last after a few 100 rounds. rely on good ol BreakFree CLP. M4 feed ramps dont matter for a semi rifle as much as they do for a Full auto. Were they using M4 feed ramps before the M4?
your concerns arent much of a issue. Enjoy your new rifle. Take care of it and it will take care of you.

Ok Ok, I see now. I used to have M4 feed ramps on both of my Bushmaster rifles and I figured that if they have them, then Stag would use them. But, the rifle has an excellent finish/fit, and I am otherwise pleased with it.
