Midwest Industries Gen 2 Mid-Length 4-Rail HandGuard for AR Rifles - Black (MCTAR-21G2)

The Midwest Industries Gen 2 Mid-Length 4-Rail HandGuard brings serious modularity and performance to your AR rifle platform. This free-float handguard is built for shooters who want room to mount optics, lights, lasers, and other tactical accessories without compromise. The two-piece design installs in minutes—though you'll need to remove the delta ring during setup—and gives you the kind of rail real estate that matters when you're building a gun that works exactly the way you want it.

What sets this handguard apart is the combination of lightweight construction and genuine versatility. Four anti-rotation QD sockets let you attach push-button sling swivels exactly where you need them, while the four integrated 1913 mil-spec rails give you unlimited mounting options across the forend. The free-float design means your barrel isn't touched by the handguard, letting it harmonize naturally—a real advantage if you're serious about accuracy at distance or competing. It's also engineered to work with most quality piston systems, so it fits into a wide range of upper receiver setups.

Midwest Industries machines this piece from 6061 aluminum and builds it right here in the USA. The attention to detail shows: clean lines, solid lockup, and enough versatility to handle hunting, 3-gun, or precision rifle duty. Whether you're upgrading a mid-build or retrofitting a rifle that needs better real estate for your mission-critical gear, this handguard delivers the performance and modularity that separates a purpose-built rifle from a generic one.
