Geissele Automatics Super Modular Rail MK18 Handguard – M-LOK / Arca-Swiss – Black – 16″


Out of stock



The Geissele Automatics Super Modular MK18 Handguard is built for precision shooters and features the same profile as the MK16 but has a smaller diameter and interfaces with the Arca-Swiss quick release system for mounting to bipods and tripods. Additionally, along the sides are M-LOK attachment slots to save weight while still giving you plenty of room for adding accessories if you need to. The upper continuous rail gives you a solid mounting platform for iron sights or other aiming solutions without fear of losing zero. The Geissele MK18 free float handguard attaches with an extra long barrel nut for increased surface area to ensure the rail wont flex under pressure. The MK18 16” Handguard is precision machined from 6061-T6 aluminum and hardcoat anodized black. If you are a precision competition shooter, the Geissele MK18 Super Modular M-LOK handguard is for you.

Note: Does not include barrel nut wrench.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.
