I would recommend contacting the manufacture.
Adams Arms (727) 853-0550
it doesn't work with standard A2 handguards. They have one on the Adams arms website that will work, it's A2 style. but oval shaped, not round. Need to drill out the front delta ring to make it work, standard gas tube hole isn't wide enough. probably a little late for the answer. I have the Daniel defense 7" Omega rail paired with mine. it uses the rear delta ring. But it doesn't require the front one. so it's still technically a free float. I also know Magpul handguards will work with them also. But like the oval one, you'll need to drill a larger gas tube hole in the front delta ring. It's hard to find handguards for piston systems right now. Most have been discountinued or are out of stock
