Product Description
The Geissele Automatics Super Modular MK4 Federal Rail is a compact, free-float AR-style handguard engineered for strength, modularity, and M-LOK compatibility. Originally selected for its rugged performance, this 10-inch rail combines a full-length M1913 Picatinny top rail with strategically placed Picatinny sections and M-LOK slots to support lights, grips, sling mounts, and other accessories while maintaining a slim, controllable profile. Its ventilated design promotes airflow around the barrel to aid heat dissipation, and the OD Green hardcoat anodized finish provides a durable, low-glare appearance.
