If you already have an LCT, GHK, or 5KU B-11 handguard and want a proper rail on top rather than a flat plate, the B-12 is the piece you replace.
It's an upper-section swap — 3.93 inches of full-length Picatinny rail, milled from aluminum alloy and finished in black — that slides over the existing handguard's top half. The lower remains in place, so your side rails, attachment points, and overall profile stay exactly as they are. You get optic-ready from the factory without pulling the whole handguard off and ordering a different one.
It fits B-11s from LCT, GHK, and 5KU. It ships as the upper handguard only, so you're keeping what you already own and adding just the one piece.
