T-marks are kinda a personal choice. I believe the "technical" reason for them is if you attach and detach optics from your top rail often. With the T markings, you can put the device on the exact part of the rail you had it on before as they rails are numbered.

M4 feedramps are a new design in the upper AND the barrel extension that alledgedly aids in the feeding of ammunition from the magazine to the chamber. If you give me a couple seconds I should be able to find the thread that explains the whole thing.

I have them on the midlength carbine I just built. Probably more show than go, but I have them.


Here is the post that will tell you everything you want to know about M4 feedramps.... and then some.

t-marks are a personal choice.
I don't have them and I manage to put my aimpoint back on in the same spot every time.

feed ramps.... well my jury is still out on them. I would say that I don't need them. depends on what your doing though.

I'd get a ramped receiver and barrel before I got "T" marks. They're pretty and cool, but it isn't hard to mount an optic in the same spot.
