Aluminum OTS® Picatinny Carbine Length Handguard

Upgrade your AR15, M4, or M16 carbine with the IMI Defense™ Aluminum OTS® Picatinny Carbine Length Handguard — a rugged drop-in rail system designed to extend usable handguard space while fitting over the standard A2 front sight gas block.

Built from durable 6061 aluminum, this handguard gives your rifle a stronger, more versatile accessory platform without requiring a full free-float conversion. The two-piece clamshell design installs using the standard delta ring assembly, barrel nut, and round front handguard cap — with no gunsmithing required.

The OTS® — Over The Sight — design wraps around the front sight post, providing extended coverage, improved support-hand placement, and added accessory space. Full-length Picatinny rails at the 12 and 6 o’clock positions allow secure mounting for optics, lights, lasers, vertical grips, hand stops, bipods, and other tactical accessories.

With its slim 1.8" wide profile, durable aluminum construction, and drop-in installation, the IMI Defense™ Aluminum OTS® Picatinny Handguard is a practical upgrade for carbine-length rifles that need more mounting space, better handling, and mission-ready durability.
