Clean and lube what exactly? What is under the free float rail you need to lube on any sort of regular basis?
Anyway, for the price I'd just go with the YHM and forget the whole endcap thing. Without a front sight base and front sight post, you'll have to fudge it with that ring thing. Just go free float, (you'll be glad you did later, trust me) and wala. You already have the low profile gas block so you're half the way to free floating already. And for the record, I have the endcap, and think it makes it look 10x cleaner. Also, you may want to research the lightweight version. I've heard they come loose often. I have the diamond and it's rock solid BTW.
