Midnight Chrome 16-inch Carbine-Gas 1:8 .223 Wylde AR-15 M-Lok Rifle Full Build Kit

The Midnight Chrome is a complete AR-15 build kit designed for shooters who want a reliable, accurate rifle without the assembly complexity. This kit includes everything except the lower receiver, which is the only federally regulated component. You get a cryo-treated, phosphate-finished barrel paired with a free-float M-Lok handguard that keeps rounds on target. The carbine-gas system cycles smoothly with a standard mil-spec trigger and a SOPMOD-style collapsible stock that adjusts to fit your shooting position.

Midnight Chrome Finish and Durability

The upper receiver uses a cryo-treated barrel with phosphate finish, a proven combination that resists corrosion and handles repeated cycling. The handguard's black chrome finish complements the upper while maintaining durability. Cryo-treatment strengthens the steel at the molecular level, improving longevity and consistency. This finish approach is standard for reliable duty-grade rifles and stands up to regular shooting.

Free-Float Accuracy and M-Lok Flexibility

The 15-inch free-float handguard isolates the barrel from the upper receiver, removing contact that can throw off shots. This design improves group consistency without requiring custom bedding or tuning. The monolithic Picatinny top rail gives you a solid mounting surface for optics, and the M-Lok slots along the sides accept lights, grips, and other accessories. You can configure this rifle exactly as you need without modifying the handguard itself.

.223 Wylde Chamber and Barrel Performance

The .223 Wylde chamber accepts both .223 Remington and 5.56 NATO ammunition, giving you flexibility at the range or in the field. The 1:8 twist rate stabilizes bullets from 55 grains up to 77 grains, making this barrel accurate across common hunting and target loads. The 16-inch length balances velocity and handling, producing roughly 2,700 feet per second with standard 55-grain loads while keeping the rifle compact and maneuverable.

Carbine Gas System and Reliability

The carbine-length gas tube and low-profile gas block cycle the bolt carrier group smoothly without excess back pressure. This system is proven reliable across thousands of rounds and requires minimal maintenance. The micro low-profile gas block sits low on the barrel, keeping your sight line clear and reducing snag points. Standard mil-spec components throughout mean parts are easy to find and swap if needed.

Complete Lower Parts Kit and Fire Control

The kit includes a standard curved mil-spec trigger, hammer, disconnector, safety selector, and all required pins and springs. These are reliable, predictable components that function well for general shooting. The trigger breaks cleanly with standard mil-spec pull weight. If you want a lighter or smoother trigger later, the lower receiver accepts drop-in upgrades without modification.

Stock, Buffer, and Ergonomics

The SOPMOD-style collapsible stock adjusts across six positions to fit different shooters and gear setups. Integrated QD sling mounting points let you attach a sling quickly, and the storage compartments hold small items like cleaning patches or batteries. The 3 oz. carbine buffer paired with the standard recoil spring produces manageable recoil and cycles reliably with standard ammunition.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. BCG and charging handle are not included in the upper build kit components.
