12.6" Super Modular Rail MK20 M-LOK®
12.6" Super Modular Rail MK20 M-LOK®
The Geissele MK20 rail, developed specifically to meet strict weight requirements for use on Border Patrol Rifles, will now be offered as a standalone option able to be installed on any standard mil-spec AR-15 upper receiver.
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 o’clock position and M-LOK™ slots on the 3, 6, and 9 o’clock 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.
