Daniel Defense
The Midwest Industries Rifle Length AR-15 Gen 2 quad-rail drop-in handguard transforms your AR platform with genuine tactical rail real estate—no gunsmith visit required. This two-piece design slides onto your rifle like a factory plastic handguard, making it one of the easiest upgrades you can do at home. Whether you're building a precision rifle, a tactical setup, or just want room to mount lights, lasers, and other optics on your forend, this handguard delivers the accessory mounting options modern shooters expect.
Built from 6061 aluminum and hard coat anodized for durability, the Gen 2 quad-rail keeps weight to a minimum while providing genuine 1913 mil-spec rails on all four sides. That means full compatibility with standard tactical accessories and proven reliability in the field. The handguard includes four anti-rotation QD sockets for push button sling attachment points, giving you flexibility in how you rig your rifle. Midwest Industries designed this specifically for most gas piston systems, so it works across a wide range of AR builds without modification.
Made in the USA by a brand known for attention to small details, this handguard represents straightforward engineering: solid materials, no complications, genuine utility. If you're running an AR and want to upgrade from plastic to a functional, lightweight rail system, this drop-in delivers the mounting space and ease of installation that makes it a practical choice for hunters, range shooters, and tactical enthusiasts alike.
