Midwest Industries 1913 Milspec Rail Section 7 Slot M-LOK compatible MI-7MR

The Midwest Industries 1913 Milspec Rail Section 7 Slot M-LOK Compatible (MI-7MR) is a precision accessory rail designed for operators who demand modular firearm customization without added weight. This 7-slot Picatinny rail integrates seamlessly with M-LOK compatible handguards and chassis systems, allowing rapid mounting and repositioning of tactical optics, lights, and other accessories. At just 0.07 lbs, the MI-7MR adds minimal mass while maintaining full 1913 Milspec compliance—the industry standard for rifle-mounted rail systems.

The 7-slot configuration provides five mounting positions across a compact footprint (3.05 inches long, 0.65 inches wide), giving users flexible optic and accessory placement without consuming excessive handguard real estate. The M-LOK interface accepts standard M-LOK fasteners, enabling tool-free attachment and removal. Midwest Industries manufactures this section to Milspec tolerances, ensuring repeatable accuracy and compatibility across AR platforms and other rifles featuring M-LOK slots. The thin, low-profile design preserves sight lines and doesn't interfere with charging handles, forward assists, or adjacent accessories.

Operators building modular patrol rifles, precision AR platforms, or short-range fighting carbines benefit from this rail's ability to support rapid accessory swaps during training or duty transitions. The section works equally well on lightweight precision builds where every ounce matters and on full-featured duty carbines where configurability drives mission readiness. Serious shooters, tactical trainers, and law enforcement armorers familiar with M-LOK systems will recognize this rail as a straightforward solution for extending mounting capability without proprietary tools or complex installation procedures.
