The Geissele Automatics Super Modular Rail MK16 is designed for the URG-I program and has been adopted by the USASOC due to its outmatched performance. This AR-15 handguard comes with the updated Geissele barrel nut that is longer providing more surface area for superior rigidity. Additionally, the SMR MK16 features anti rotation tabs and set screws to ensure the rail won’t rotate under any circumstance. The picatinny top rail and seven sides of M-LOK slots offers plenty of customization options while reducing weight. The Geissele MK16 Super Modular Handguard is precision machined from 6061-T6 aluminum and hardcoat anodized black.

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.

I've had an used a few different ALG and Geissele rails, but I settled on the MK16 for this build. Machining and finish are great, included hardware is great. The real winner is the engineering. No timing necessary for the barrel nut. Solid attachment and lockup. Incredibly slim, but strong and Geissele provides above average drawings and information so you can make sure you know it will fit with your build. I wouldn't hesitate to recommend this rail.
