Description

Upgrade your AR15, M4, or M16 carbine with the IMI Defense™ MRS AR15 Modular Quad Rail Systems — a lightweight, ergonomic handguard designed for modular accessory mounting without unnecessary bulk.  Available in Carbine, Mid-length, and Rifle Length.

Built from durable fiber-reinforced polymer, the MRS provides a strong yet lightweight platform for carbine-length rifles. Its slim cross-section improves handling, while the modular rail layout gives shooters flexibility to configure the handguard around their preferred setup.

The full-length T-marked Picatinny top rail provides a reliable mounting surface for sights, optics, lights, and accessories. Optional side rail sections and a full-length bottom rail section allow you to add mounting space where needed while keeping unused areas clean and comfortable.

Integrated anodized aluminum heat shields and ventilation slots help manage heat around the barrel during extended use. The handguard drops into place between a Mil-Spec delta ring and handguard cap for a tight fit and is compatible with round end caps.

A front bottom QD sling mount adds sling attachment capability, making the MRS a practical, adaptable upgrade for carbine-length AR15 platforms.
