Geissele 15in Super Modular Rail MK4 M-LOK

The Super Modular Rail MK4 M-LOK from Geissele is an ultra-lightweight option for full-size AR builds. At 15 inches in length, these rails are purpose-built and feature integrarted Picatinny rail sections at the front of the rail in the 3, 6, and 9 o’clock positions. The free-floating design also lends itself to efficient barrel venting, ensuring heat can dissipate swiftly after you fire. The MK4 Super Modular Rail also has M-LOK connections along the rails and in the upper 45 quadrants so that you can mount a variety of accessories to customize your weapon to your exact needs. The modular nature and versatility of the MK4 is what makes it stand out from the crowd, giving you options for tactical, functional, and sport shooting upgrades. The Super Modular Rail MK4 also features the Geissele’s proprietary 2.25-inch long barrel nut, which is larger and stronger than other varieties. The extra length increases the nut’s surface contact where the rail interfaces with the receiver, creating a platform that is straight and true. With the extra rigidity, you can maintain your accuracy and zero-in your optics reliably.
