Aim Sports MT021 M4 Carbine Length Quad Rail Handguard 6.5" Black Anodized Aluminum - AR-15, M16, M4

The Aim Sports MT021 is an M4 carbine-length drop-in quad rail handguard designed as an easy, no-gunsmithing upgrade for the basic AR-platform carbine. Built from aircraft-grade aluminum with a durable black anodized finish, this two-piece handguard drops directly onto most carbine-length direct impingement gas systems for a fast, hassle-free installation.

At 6.5" long and weighing 11.03 oz, the MT021 wraps the entire handguard in a continuous Picatinny rail, giving you ample mounting surface for lights, lasers, foregrips, bipods, and other standard Weaver/Picatinny 1913 accessories. The drop-in two-piece design clamps securely to the factory delta ring and barrel nut without permanent modification, making it a popular budget-friendly way to convert a standard M4 carbine into a more versatile accessory platform.

Compatible with AR-15, M4, and M16 carbines, the MT021 brings quad-rail utility to your rifle while keeping weight and cost down. Whether you're setting up a defensive carbine, a training rifle, or a range plinker, this handguard delivers the mounting real estate you need in a simple drop-in package.
