Geissele Super Modular MK4 M-LOK Handguard
The Super Modular Rail (SMR) MK4 M-LOK represents Geissele's commitment to delivering a handguard that balances weight savings with uncompromising strength and accuracy.
Key Features
- Integrated Picatinny Rails: Short M1913 picatinny rail sections at the 3, 6, and 9 o'clock positions provide mounting flexibility without adding unnecessary weight
- M-LOK Compatibility: Full M-LOK slots at the 3, 6, and 9 o'clock positions, plus upper 45-degree quadrants, allow you to attach accessories exactly where you need them
- Maximum Venting: Strategically designed ventilation dramatically reduces overall weight while maintaining the rail's rigid platform and heat dissipation
- Proprietary Barrel Nut: Geissele's 2.25" long barrel nut increases surface contact with the receiver, ensuring a straight and true free-float rail
