Description

Upgrade your AR15, M4, or M16 carbine with the IMI Defense™ Aluminium Quad Rail Carbine Drop In — a rugged, lightweight drop-in handguard designed for strength, secure fit, and full mission adaptability.

Machined from aircraft-grade aluminum, this two-piece quad rail handguard delivers a solid, precise fit while maintaining a slim profile for improved handling. Designed for easy installation, it drops directly onto compatible rifles with no gunsmithing required, making it a practical upgrade for both professional users and civilian shooters.

The handguard features T-marked Mil-Spec 1913 Picatinny rails at the 3, 6, 9, and 12 o’clock positions, giving you full flexibility for mounting optics, lights, lasers, grips, sling accessories, and other mission-critical gear. A friction-fit ledge with roll pins helps provide secure locking and dependable retention.

With five QD sling mount ports — two on each side and one at the front of the bottom rail — plus an ultra-slim 2.2" width, this handguard is built for versatility without unnecessary bulk.
