Geissele Super Modular Rail MK8 M-LOK

Ultra-Modular Design

The Super Modular Rail (SMR) MK8 M-LOK™ is Geissele’s ultra-modular model, designed to give users full modularity while maintaining a strong and rigid platform. Maximum venting at the lower 45° quadrants ensures optimal heat dissipation and significantly reduces overall weight.

Versatility and Modularity

Utilizing Magpul’s M-LOK technology at the 3, 6, and 9 o'clock positions, as well as the upper 45° quadrants, the SMR MK8 allows users to customize their platform to suit unique needs.

Enhanced Barrel Nut Design

• Barrel Nut Length: Features Geissele’s proprietary 2.25" long barrel nut.
• Improved Contact: Increases surface contact with the receiver for a straight and true platform.
• Accuracy and Zero Repeatability: Maintains precision during disassembly and reassembly for maintenance.
