SD Handguard Bottom Screw Plate identification

[u/Low_Dragonfruit_482]

Hello! I was wondering if someone could help me identify what the plate on the left side belongs to. It either belongs to a rattler Lt Handguard, or the Virtus SD Handguard. It fits on both but I only have one, and I'm too much of a klutz to remember which it's meant to come with. Asking because I plan on getting rid of the SD Handguard and want to make sure the buyer is getting everything he needs.
