I am putting my new upper together and noticed the upper receiver that I bought doesn't have M4 feed ramps like I thought. Will it work for the Grendel?

It should more than likely work. This has been discussed in a number of other threads, but you should be GTG.

ETA: Your circumstances would be covered in the pictures as the one labeled as "OK". (Barrel extension w/ ramps, upper w/o)

You da man!

I believe you will be fine. If you reversed the scenario, then there would be issues. So if you had M4 ramps on the lower but not the barrel extension, then you would likely have an issue.

Oops, I guess I should've gone to the link posted by Nugginfutz before I replied. The picture says it all and in a much better way than the words I cobbled together.

You were concise and on point, KTC. No apology needed. I just happened to remember that post, and how much those who contributed to it. It was a no-brainer, when deciding whether to reiterate or just link to that thread.
