So I am looking at an upper that comes with a free float round handguard on it. My question is this, how do you mount a bipod to it? Drill holes in the handguard and mount a sling stud? I have been looking, but I haven't been able to find anything yet. Here is the upper I was looking at for reference. It has no holes. I don't want a 20" bull barrelled rifle that I cannot put a bipod on. If I have to add something that's fine, I just haven't seen anything.
