The Midwest Industries MICRM45 is a 4.5" free-float handguard purpose-built for AR-15 platforms that need serious modularity without sacrificing accuracy. Machined from 6061-T6 aluminum and hardcoat anodized in black, this combat-grade rail gives you the flexibility to mount optics, lights, and other tactical gear exactly where you need them. Whether you're setting up a precision rifle, a duty gun, or something in between, the MICRM45 keeps your barrel truly free-floated so your accuracy doesn't suffer from handguard pressure.

The design centers on M-LOK attachment versatility—seven rows of M-LOK slots run the length of the handguard, giving you endless options for mounting accessories on the sides and bottom. The top features a continuous Picatinny rail for your scope, red dot, or clip-on magnifier, so you're never short on rail real estate. Two quick-detach sling attachment points are built in with an anti-rotation design to keep your sling stable and secure.

Every detail reflects Midwest Industries' commitment to quality: the aluminum is American-made, the barrel nut is heat-treated for durability, and installation is straightforward with the included wrench. This handguard is not compatible with gas-piston AR platforms or certain billet upper receiver designs, so verify fitment before ordering if you're running a non-standard upper.
