Looking for hand guards for a mid length with a round handguard cap. Anything out there besides MOE and Surefire?

It looks like the great majority of middys come with triangle caps so most drop in handguards are made for that. The MOE handguards are made to work with both types of caps.

You could get a 2 piece free float rail and not worry about the cap at all.

Or you can remove the FH and FSB and change the cap to a triangle one.

Are you looking for drop-in or free floating handguards?

Here are a list of manufacturers some sells both drop-in and free floating, some only free floating.
