Can someone please explain to me about the M4 feed ramps? I really don't understand what the differences are. Meaning extended feed ramps, M4 ramps. I just looked at the Larue upper and it said A3 style no M4 feed ramps and didn't understand it. I currently have a LMT 10.5" upper, what does it have?  Thanks

A3 is commonly referred to as rifle extensions

What a coincidence you saved this question for post #223. Someone will attach the M4 feedramp comparison photo soon enough. The M4 ramps really assist feeding when used in full auto. Nice to have but not necessary. M4QUADRAIL

Your LMT has M4 feed ramps.
