Mi Upper Receiver Ar15 5.56Mm - 10.5" 1:7 Carbine M-Lok No Bcg
The Midwest Industries 10.5" upper receiver for AR-15 is purpose-built for short-barrel rifle builds that demand accuracy and durability without compromise. This 5.56 NATO upper pairs a forged 7075-T6 aluminum receiver with hard coat anodizing for corrosion resistance and a lifetime of reliable performance. The 10.5" Melonite-finished 4150 Chrome Moly barrel features a 1:7 twist rate optimized for standard 5.56 rounds, paired with M4 feedramps for reliable feeding and a 1/2x28 threaded muzzle ready for suppressors or flash hiders.
Topped with a 9.5" MI Combat Series M-LOK handguard, this upper receiver provides modern modularity and clean aesthetics you won't find on older carry handles or quad rails. The M-LOK slots accept industry-standard lightweight accessories, so you can configure your rail space exactly as you need it—whether that's keeping it minimal for a lightweight truck gun or adding lights, lasers, or other gear for tactical work. At just 2 lbs 7.8 oz, it won't burden your platform.
This is an upper receiver only—it does not include a bolt carrier group, so you'll need to source a BCG separately or pair it with your existing carrier. The carbine-length direct impingement gas system is proven reliable across thousands of builds and keeps maintenance straightforward. Whether you're building a home defense SBR, a suppressor host, or a compact hunting upper, this Midwest Industries receiver delivers the fit, finish, and features serious shooters expect.
