Geissele 9.6" MK20 Dual Tab DDC Handguard Assembly 05-2554S shares the same origin as the longer MK20 rails - a Border Patrol Rifle program that demanded strict weight limits without giving up rigidity - trimmed here to the shortest length in the line. Machined from 7000-series aluminum and heavily skeletonized in non-structural areas, this Geissele MK20 locks onto the receiver through a dual anti-rotation tab clamp system paired with Geissele's easy-install barrel nut. "Easy install" doesn't mean it gives anything up, either - Geissele rates it "Super Stiff" internally, and the anti-rotation tabs and set screws back that up under recoil. A full-length Picatinny rail runs the 12 o'clock position, with M-LOK slots at 3, 6, and 9 for everything else. At 7.9 ounces bare and 9.5 with the barrel nut, this is genuinely one of the lightest all-aluminum handguards Geissele makes at any length - a real number if you're chasing a weight target on a compact build rather than just wanting something that sounds light.
