SRU SARB15 M4 Airsoft GBB Extended Handguard – Standard

Extended Front-End Upgrade for Bullpup M4 GBB Builds

The SRU SARB15 Extended Handguard is a specialized upgrade for users running the SARB15 bullpup chassis on GBB M4 platforms. Designed to replace the standard front end, this component extends the rifle's fore-end to offer increased stability and mounting space for accessories, without compromising the bullpup layout.

Purpose-Built for SARB15 Compatibility

This handguard is engineered specifically for the SRU SARB15 bullpup chassis, ensuring a seamless fit and continued aesthetic. It preserves the original bullpup functionality while enhancing the balance and customization potential of your setup.

Lightweight Polymer Design

Manufactured from reinforced high-strength polymer, the handguard maintains a low weight profile—ideal for players seeking extended setups without adding excessive front-end weight. The open-grid design promotes ventilation and aggressive styling.

Extended Rail System

With additional Picatinny mounting slots along the top, bottom, and sides, this extension allows for the integration of foregrips, lights, and laser aiming modules. Perfect for users who require more real estate for accessories in dynamic environments.
