Polymer Drop-In M-Lok® Handguard

Upgrade your carbine-length AR15, M4, or M16 platform with the IMI Defense™ Polymer Drop-In M-Lok® Handguard — a lightweight, slim-profile handguard built for fast installation, improved handling, and tactical accessory mounting.

Molded from durable glass fiber-reinforced polymer, this handguard delivers strength without unnecessary weight. Integrated heat shields help provide thermal insulation and added shooting comfort during extended use, while the ultra-slim 1.5" wide profile keeps the rifle compact, controllable, and easy to handle.

The full-length T-marked 1913 Mil-Spec Picatinny rail at the 12 o’clock position allows for secure top-mounted accessories, while M-Lok® slots at 3, 6, and 9 o’clock provide flexible attachment points for lights, grips, rail covers, sling mounts, and other tactical gear.

Designed for fast, no-gunsmith installation, the IMI Defense™ Polymer Drop-In M-Lok® Handguard gives shooters a simple, durable upgrade for carbine-length rifles.
