The Midwest Industries SP-Series AR-15 12.625" handguard is a purpose-built one-piece free-float rail system built for serious shooters who demand modularity without compromises. Machined from 6061 aluminum and finished with hard coat anodizing, this handguard combines durability with practical mounting flexibility—seven M-LOK slot arrays run the length of the rail, giving you multiple options for lights, lasers, grips, and other tactical accessories. Whether you're setting up a precision rifle, a home-defense carbine, or a range gun, the SP-Series provides the real estate and weapon compatibility you need.
The full-length Picatinny rail on top integrates seamlessly with standard optic mounts and accessories, while the M-LOK slots on the sides and bottom (along with a included 5-slot rail) keep your setup clean and lightweight. The 1.75" inner diameter and 2" outer diameter geometry was engineered with suppressors in mind—you'll have clearance for most modern cans without fitment headaches. Midwest Industries includes the barrel nut wrench and all hardware needed for installation, so you're ready to build out of the box.
Built entirely in the USA, the SP-Series reflects Midwest's reputation for attention to detail and reliability. This is not a compromise handguard—it's a platform designed for shooters who understand that modularity and ruggedness aren't mutually exclusive.
