@Farstriker, like @Dave J, I prefer the half-ghost ring. I'm back to using the OEM handguard after giving the Magpul/Aridus one a good try, and am very happy. For me, the OEM handguard has better ergos, and the M-Lok attachments to the plastic felt flimsy. It was easy to bend the plastic handguard by pulling on the WML or sling mount, and I couldn't get used to that.
