I am installing a YHM free float lite weight fore arm on my H-bar. Barrel measures .755" where the end of the fore arm stops. Which of the two end caps is correct for this set up?

My feeble math skills point to the 1 1/16" size, as the smaller 15/16" would only leave .0912 clear around the barrel (1.46 16ths). Seems a little sparse for space?

yes you want the 1 1/16"

I don't have a YHM FF rail, but I think they have the coolest looking end cap. I think you are wise to put it on, even if it just for the cool factor. Did you go with a low profile gas block and a rifle length lite weight fore arm? That makes the end cap more visible and even better looking.
