Nice rifle, I bet you are glad you bought it before the panic set in.
If you aren't going to put a light on it (since you sold the one you had), why don't you just get a stock type handguard? If you decide later to add another red dot, it can be added to the rail on the upper receiver. If you want to have a back up rear sight, add a folding version behind the optics.
Like this:
I tried a rifle with a railed handguard and found it to be bulky and uncomfortable. I have no use for them as I have no intention of adding a bunch of mall ninja accessories on my rifles and for me, I see no use for a bipod on what is essentially a battle rifle.
Just my opinion.
