The Midwest Industries Lightweight in .223 Wylde (MPN MIFN16CRM15) is a semi-automatic AR-15 built to shoot both 5.56 NATO and .223 Remington accurately, pairing a lightweight Melonite 16-inch barrel with a 1:8 twist rate and a .625-inch diameter. Midwest Industries forges the receiver from 7075-T6 aluminum machined to M16/M4 specs with M4 feed ramps and a hard-coat anodized Mil 8625 Type III Class 2 finish. The MI M16 bolt carrier group runs a mid-length gas system, and a 16-inch MI-CRM Combat Series M-Lok handguard leaves extra room for accessories ahead of an A2 flash hider. The rifle wears a Magpul CTR stock and Magpul MOE grip on a mil-spec buffer tube, uses a manual thumb safety, and feeds from a detachable magazine with a 30+1 capacity. It ships optic-ready with no fixed sights. Among AR-platform rifles in the AR rifles category, this rifle favors shooters who want a longer M-Lok handguard on a dual-caliber .223 Wylde AR-15.
