Forend Pump Handguard with Side Rails & Vertical Grip for Mossberg 500 / Maverick 88 – 12 Gauge

Upgrade handling, control, and accessory mounting options with this Forend Pump Handguard with Side Rails and Vertical Grip, designed for Mossberg 500 series and Maverick 88 12-gauge platforms.

This forend is built to fit long action slides measuring 7-3/4 inches and is compatible with current production models that use integrated action bars (no removable inner metal tube required). Constructed from high-impact injection-molded polymer, it features black anodized aircraft-grade aluminum side rails, allowing attachment of standard Weaver / Picatinny 1913 accessories.

The ergonomic shape, rearward angle, and back swell help distribute recoil evenly into both hands, improving control, speed, and accuracy during operation. The included vertical grip enhances stability and provides a natural, confident hold.

Designed specifically for 12-gauge use, this forend includes action bars and installs with no gunsmithing required.

Important Compatibility Notes:
This forend is not compatible with 3.5" receivers (Mossberg 535 or 835), turkey models, youth Bantam models, or 20-gauge / .410 platforms.
