Advice on a handguard for an Armalite AR-10B

[jmichelin84]

Hello all, I'm looking for an quad rail that clamps on rather than using a retaining ring, the barrel on my rifle is 20 inches and the quad rails they have are 12 inches long and use the ring, so there is no continuous top rail, I was thinking the Tac15 rail, but it has one rail, and the add on keumod sections won't fill all the key holes on the guard.
Any ideas or advice?

Have you considered handguards from Midwest Industries. They have a 15" model for the Armalite series. It has a full top rail and is free float as it clamps onto their barrel nut. They have 2 models, one is M-Lok (MI-AR10SSM15) and the other is Keymod (MI-AR10SSK15). I was actually looking at the 12" M-Lok model for my AR15. Hope this helps.
