Triangle caps on midlength uppers are standard.

My first LW mid length CHF came with a round end cap.

It was such a great shooter that I ordered a second. It came with a triangular end cap.

Since they are set up almost identically, the different end caps allow me to remember which is which.

I guess I am out of the loop, but I don't understand why one is preferred over the other.
I am using MI 2 piece FF rails on both and there is no difference in the mounting.

Because there are standards which make the AR system modular. Certain rails won't work with non standard parts. Mid-length and rifle length use triangular handguard caps as standard across the industry.
