Midwest Industries Handguard Drop-In Alumn 4.5 Black

The Midwest Industries SIG Sauer MPX Drop-In Handguard in 4.5 inches brings practical modularity to one of the most popular pistol-caliber carbines on the market. If you're running an MPX and want to add optics, lights, or other accessories without permanent modifications, a drop-in handguard with M-LOK slots gives you the mounting flexibility to build exactly the setup you need. The 4.5-inch length keeps things compact—ideal for short-barreled configurations or shooters who prefer a lighter, handier platform for home defense, tactical training, or recreational shooting.

Midwest Industries engineered this handguard from aluminum and finished it with a hard-coat anodize in black, so it's built to take daily use without corrosion or finish wear. The M-LOK-compatible attachment points let you run virtually any modern accessory system, from rail sections to sling mounts, without drilling, filing, or permanent alterations to your rifle. Installation is straightforward—it drops in without gunsmithing or special tools.

Whether you're upgrading a stock MPX or fine-tuning a dedicated SBR, this compact handguard strikes a balance between real estate for accessories and the low profile that makes a shorter carbine easier to maneuver in tight spaces.
