Good for the money. - Trinity Force M4/AR15 Competition Series Free Float Handguard w/ Vents

I only gave it 4 stars because I thought the barrel nut seems cheap. I wish they had included shims to align the gas port tube holes to the upper better. It looks great and functions perfectly. It's not a high dollar handguard so don't expect high dollar quality. But I like it fine. It's a perfect fit over a low profile gas block and hides the gas tube and block on a 24" barrel. You'll have to do some modification if you want to mount a swivel for a sling or a bipod.
