The Geissele MK4 Federal Rail 10in M-LOK Handguard for AR-15, Desert Tan is a handguard for AR-15.

This is the same rail used to fulfill contracts for the Federal Bureau of Investigation (FBI). It's strength, modularity and M-Lok compatibility gives users the capabilities needed to successfully complete the mission at hand.

A handguard protects your support hand from barrel heat and gives you room to mount lights, grips and other accessories. Check the length and fitting type against your rifle — drop-in handguards fit between the delta ring and handguard cap, while free-float handguards use their own barrel nut.
