The Midwest Industries Combat Lightweight M-LOK handguard (MI part number MICRLW15) is a 15-inch free-float rail built for AR-15 shooters who want a slim profile without sacrificing mounting real estate. Midwest Industries machines it from 6061 aluminum in the USA, and its free-float design keeps pressure off the barrel for more consistent accuracy. A continuous 1913 Picatinny top rail runs the full length for optics and iron sights, while seven sides of M-LOK slots give shooters plenty of room for lights, grips, and bipods. It is a solid choice for a lightweight competition, duty, or general-purpose AR-15 build.
