Specifications

The Geissele Super Modular Rail MK4 Federal AR15 Handguard is a versatile and lightweight addition to any AR15 platform. It features integrated M1913 picatinny rail sections at the fore of the rail in the 3, 6, and 9 o'clock positions. Maximum venting for heat dissipation dramatically reduces the rail's overall weight while maintaining its strong and rigid platform.

Features

The MK4 M-LOK handguard is designed to be both modular and versatile, allowing users to tailor their platform to their unique needs. It includes M-LOK slots at the 3, 6, and 9 o'clock positions, as well as the upper 45 quadrants, to keep the weight on the rail system down while maintaining modularity and versatility for attaching accessories.

Strength and Durability

The rail is strong and rigid, providing rail points where needed and nowhere that isn't necessary, which helps to save weight. This durability and strength make it ideal for various applications, from tactical use to target shooting.

Installation

Installing the Geissele Super Modular Rail MK4 Federal AR15 Handguard is a straightforward process. Users will need to remove their existing flash hider, handguards, and front sight/gas block. The supplied Geissele wrench can be used to remove the stock barrel nut. Once the barrel is inserted into the upper, it is essential to lubricate the upper receiver threads and the outer face of the barrel extension with anti-seize or grease. The handguard should be slid onto the barrel nut until it is aligned, and the rail mounting bolts should be tightened to 5ft-lbs.

Additional Features

The MK4 handguard also features Geissele's proprietary 2.25" long barrel nut, which increases the surface contact where the rail interfaces with the receiver. This creates a platform that is straight and true the entire length of the free float rail, enhancing accuracy and zero repeatability during disassembly and reassembly.

Compliance

NFA (National Firearms Act) compliance is crucial for legal ownership and transfer of regulated firearms and accessories like short-barreled rifles, suppressors, and certain types of ammunition. Ensuring adherence to federal regulations helps avoid legal penalties and ensures responsible firearm ownership.

Conclusion

The Geissele Super Modular Rail MK4 Federal AR15 Handguard - Desert Dirt Color | 10" | M-LOK is a high-quality addition to any AR15 platform. Its lightweight design, modularity, and durability make it suitable for various applications. Proper installation is crucial, and users should follow the manufacturer's guidelines to ensure a secure and accurate fit.
