Geissele Automatics MK20 Free Float AR-15 Handguard - M-LOK - 9.6"

The Geissele Automatics MK20 Super Modular Rail is a skeletonized 7000-series aluminum M-LOK handguard engineered for compact AR-15 builds — pistol configurations, SBRs, and short-barrel carbines where maximum weight reduction is the primary consideration without sacrificing rigidity. At 9.6 inches and 7.9 ounces, the MK20 is among the lightest all-aluminum AR handguards available at this length, achieving its weight through aggressive material removal in non-structural areas while maintaining Super Stiff rigidity at the barrel nut interface. Anti-rotation tabs and set screws lock the rail positively to the upper receiver to prevent rotation under recoil, ensuring lights, lasers, and aiming devices maintain zero under hard use. The M1913 Picatinny top rail provides full-length optic mounting surface, and M-LOK at 3, 6, and 9 o'clock covers all practical accessory positions. A standard armorer's wrench installs the Geissele Barrel Nut — no proprietary tools required. Compatible with mil-spec AR-15 upper receivers. Geissele Automatics is a leading manufacturer of precision AR triggers, handguards, and accessories based in North Wales, Pennsylvania.
