Midwest Industries 8.0in M-LOK Handguard for SIG MPX, Black

The Midwest Industries 8.0″ M-LOK Handguard for the SIG Sauer MPX in black (Midwest Industries part no. MI-MPX8.0M) is a free-floating drop-in handguard that adds modern M-LOK real estate to the MPX platform. Midwest Industries machines this handguard from lightweight 6061 aluminum, keeping the added weight low while giving MPX owners a rock-solid mounting surface for lights, grips, and slings. The free-float design keeps the barrel isolated from handguard pressure, which helps preserve accuracy under sustained fire. A T-marked extended Picatinny top rail runs the full length for optics or iron sight mounting, while 24 full M-LOK slots plus 4 half slots wrap the sides and bottom for flexible accessory placement.
