Aluminum OTS® Full Rail Picatinny Carbine length Handguard

Upgrade your AR15, M4, or M16 low-profile gas block rifle with the IMI Defense™ Aluminum OTS® Full Rail Picatinny Carbine Handguard — a rugged drop-in rail system designed for strength, modularity, and mission-ready performance.

Machined from 6061 aircraft-grade aluminum with a durable black anodized finish, this handguard delivers a strong, slim, and professional-grade platform for tactical accessories. The two-piece clamshell design allows for fast installation using the standard delta ring, barrel nut, and round handguard cap — with no gunsmithing required.

This model features full-length Picatinny rails at the 12 and 6 o’clock positions, giving you expanded mounting space for optics, lights, lasers, vertical grips, hand stops, bipods, and other accessories. Additional M-Lok® slots at the 3 and 9 o’clock positions provide even more flexibility for rail covers, sling mounts, and side-mounted accessories.

Built for military, law enforcement, and professional shooters, the OTS® Full Rail Picatinny Handguard gives your rifle the clean, extended look of a modern tactical setup while maintaining the simplicity and convenience of a drop-in installation.
