nothing against them, but quad rails never did anything for me. I actually preferred the old hand guards, and even ‘backdated’ my issued M4 and GUU-5P to the old carbine hand guards (being the boss had its perks). Never looked back once I retired and started building them for myself.
Prefer a slimmer, round(ish) hand guard, with mlok or keymod slots (I’m agnostic) to put stuff where I need it, and nothing more.
For example:
Or old school magpul hand guards and a FSB:
An SBR’d set I built for my son:

And sometimes with no mounting options at all, LoL…
