Geissele 15" Super Modular Rail MK8 M-LOK¨ - Black: Precision and Modularity Redefined

The Geissele 15" Super Modular Rail MK8 M-LOK¨ in Black redefines precision and modularity in the realm of firearm accessories.

Engineered for Excellence

The SMR MK8 distinguishes itself with maximum venting at the lower 45¡ quadrants for superior heat dissipation, significantly reducing the overall weight without sacrificing strength. Magpul's M-LOK technology enhances the rail's versatility at the 3, 6, and 9 o'clock positions, as well as the upper 45¡ quadrants, allowing for a fully tailored shooting experience.

Unmatched Stability and Accuracy

Featuring Geissele's proprietary 2.25" long barrel nut, the MK8 increases the surface contact with the receiver, ensuring a perfectly straight and true alignment throughout the entire length of the rail. This not only increases the rail's stability but also significantly enhances accuracy and zero repeatability during maintenance operations.
