Description

Upgrade your AR15, M4, or M16 carbine with the IMI Defense™ Polymer OTS® M-Lok® Carbine Length Handguard — a rugged drop-in handguard designed to improve handling, accessory mounting, and front-end coverage without requiring gunsmithing.

Built from durable glass-reinforced polymer, this handguard delivers strength while keeping weight and heat transfer lower than many aluminum handguard options. The integrated internal heat shield helps reduce heat buildup during extended use, giving your support hand added protection and comfort.

The OTS® — Over The Sight — design extends around the A2 front sight gas block, providing added coverage and more usable handguard space. Its two-piece clamshell construction installs with the standard delta ring assembly, barrel nut, and round front handguard cap for a secure drop-in fit.

A full-length Picatinny top rail at the 12 o’clock position gives you a solid mounting platform for optics, sights, lights, and accessories, while M-Lok® slots at 3, 6, and 9 o’clock provide flexible attachment points for grips, rail covers, sling mounts, and other tactical gear.

With its slim 2.22″ wide profile, integrated heat shield, and carbine-length compatibility, the IMI Defense™ Polymer OTS® M-Lok® Handguard is a practical upgrade for shooters who want modern modularity, improved ergonomics, and fast no-gunsmith installation.
