Innovative Free-Float Handguard For Excellent Flexibility & Comfortable Grip

The Diamondhead VRS-T Series 3 is an innovative Free Floating Handguard that offers an uninterrupted rail extension in perfect alignment with the host weapon’s flat-top receiver. It features a “T” rail that replaces the factory delta ring and barrel nut and it provides excellent flexibility of use when adding M-LOK configured accessories.

VRST S3 M-LOK Handguard provides a lightweight, durable, ergonomic, and modular design for the shooter and offers finger grooves that are milled into the handguard for a more positive grip while firing.

Machined From 6061 Aluminum

The Diamondhead VRS-T M-LOK handguard is machined from 6061 aluminum and has a hard coat anodized black finish.  The Picatinny top rail sits flush with M4 flat-top upper receivers and allows you to have more space for optics and backup iron sights.

The M-LOK attachment system runs the length of the rail at the 3, 6, and 9 positions for flexibility when configuring accessories, and the slim profile with the grooved bottom is comfortable to grip while still allowing enough room for low profile gas blocks underneath.
