whats the heaviest, fattest free float handguard I can get for ARs?

A solid block of steel

probably the KAC rail mounted on a DCM match tube like what the USMC service rifle team uses. It's expensive af tho

if you're optimizing for FF + lowest weight, literally use a DCM tube, A2 handguards + lead weights.

>>33912977
err, lowest price, heaviest weight

>>33912977
I just want a giant heavy as fuck AR

>>33912865
