From the manufacturer
Geissele Handguard Assembly Mk20 - Dual Tab 12.6in Black. Due to its innovative skeletonized design the MK20 is one of the lightest all-aluminum rails available for the AR-15 platform. Despite its light weight the use of high-quality materials and the easy on/off Geissele Barrel Nut allows the MK20 to maintain a Super Stiff level of strength and rigidity. Anti-rotation tabs and set screws ensure that the MK20 will not rotate even when subjected to rigorous use. M1913 picatinny rail on the 12 oclock position and M-LOK slots on the 3 6 and 9 oclock positions provide ideal modularity for mounting accessories. When a minimalist yet reliable handguard is required for a rifle where weight savings is a primary consideration there is no option but the Geissele MK20 Rail.
