5KU 7 Inch SMR MK8 M-LOK Handguard - M4 AEG / GBB

5KU 7” SMR MK8 M-LOK Handguard is a CNC-machined aluminum handguard designed for M4/AR series airsoft replicas. Featuring a Geissele-style MK8 Super Modular Rail design, it combines a full-length 20mm Picatinny top rail with an M-LOK mounting system in a compact 7-inch configuration, ideal for short-barrel builds and CQB setups.

The 5KU SMR MK8 7” is designed to modernize your M4/AR platform with a slim and rigid rail system while keeping the overall build compact and lightweight. Weighing only 251 g, this handguard is well-suited for fast handling and close-quarters gameplay where maneuverability matters.

The full-length 1913 / 20mm Picatinny top rail allows secure mounting of red dot sights and other aiming devices. M-LOK slots on the sides and bottom provide flexible attachment points for grips, weapon lights, lasers, and other M-LOK-compatible accessories without adding unnecessary bulk.

The handguard includes a barrel nut and is compatible with most AR / M4 series AEG, GBB, MWS, and CGS-spec replicas. Minor fitting may be required depending on individual manufacturer tolerances.
