Geissele Super Modular MK4 Federal AR-15 Handguard - M-LOK - 10"

The Geissele Automatics Super Modular MK4 Federal AR-15 handguard is the same free float rail built under contract for the Federal Bureau of Investigation, now available for your own build. Built for the M4 carbine and mil-spec AR-15 variants, this 10" handguard delivers the durability and modular mounting that operational use demands.

• 10" free float design
• M-LOK compatible slots
• Includes proprietary Geissele barrel nut
• 7000-series aluminum construction
• Black hardcoat anodized finish

Integral M1913 rail sections at the muzzle end accommodate lights and bipods, while M-LOK slots along the body keep the rail light without sacrificing strength. The included barrel nut increases surface contact where the rail meets the receiver, holding the platform straight and true so zero repeats reliably after maintenance or a barrel swap. This is the same variant supplied under contract to the Federal Bureau of Investigation, giving civilian and law enforcement shooters access to a handguard built to the same specification trusted for operational use in the field.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. Established in 2004, the company built its reputation on the Hi-Speed National Match trigger, a success that led to a select-fire trigger contract with U.S. Special Operations before Geissele brought a semi-automatic version to the civilian, competition, and law enforcement markets.
