Andro Corp Industries Bravo .300 Blackout Complete Upper Receiver - 16" 4150 CMV Steel Barrel, 15" Free-Float M-LOK Handguard, Pistol-Length Gas System, Forged 7075-T6 Receiver, Matte Black Anodized Finish - U30016ML / 736684144777
Product Description
Assembling a high-performance hog-hunting rifle, configuring a modern defensive carbine, or staging an adaptable .300 AAC Blackout system requires a barreled upper assembly built to perfect cycling pressures. Using sub-optimal gas system lengths on large-bore micro-propellant rounds can drop chamber velocity, resulting in continuous short-stroke failures with subsonic hunting loads on your bench. The **Andro Corp Industries® Bravo 16" .300 Blackout M-LOK Upper Receiver (U30016ML / 736684144777)** completely flatlines these cycling and customization bottlenecks, delivering a headspaced, factory-assembled **complete barreled upper package** optimized for heavy caliber versatility.
Proudly assembled, calibrated, and live-fire tested in the United States by Andro Corp Industries, this duty-grade upper is machined from a forged **7075-T6 aircraft aluminum alloy** shell finished in a non-reflective Mil-Spec Type III hard-coat anodized layer. At the absolute core of the structure sits a premium **16-inch 4150 Chrome Moly Vanadium (CMV) steel barrel** featuring a versatile 1:8 twist profile and an ultra-hard liquid melonite barrier skin. Tuned perfectly for the unique burn rate of .300 BLK powder charges, it utilizes a dependable **pistol-length gas system** to guarantee reliable extraction dwell times with both light supersonic and heavy subsonic suppressed target ammunition. Encased in an ultra-slim **15-inch free-float aluminum M-LOK handguard** with a continuous top Picatinny deck, this turn-key tactical assembly upgrades your weapon build straight from your workbench.
Engineered to drop instantly onto standard mil-spec lower receiver pins, this factory-calibrated complete upper assembly ensures absolute reliability directly from your workspace bench.
*Armorer Bench Notes & Real-World Upper Staging Guidance: The Andro Corp U30016ML complete barreled upper assembly arrives workspace ready, containing the pre-machined 7075 upper housing, forward assist plunger, spring-loaded port cover door, 16" melonited barrel, low-profile gas block, pistol-length gas tube, 15" free-float M-LOK handguard, and a factory-timed A2 birdcage flash hider. MIL-SPEC PIVOT AND TAKEDOWN INTERFACE MATRIX: The lower alignment yokes are engineered natively, strictly, and dimensionally to drop onto **any standard AR-15 mil-spec lower receiver chassis featuring 0.250-inch pivot and takedown pin settings**. *BCG and Charging Handle Completion Checklist:* Please note that this specific SKU is a *barreled upper layout group* and does **NOT include a Bolt Carrier Group (BCG) or Charging Handle** on your bench. To complete the staging assembly, verify you have a quality 5.56/.223/.300 BLK full-auto profile BCG and standard charging handle ready. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host lower receiver is completely clear of live ammunition, the magazine is removed, and the fire control area is safe. 2. Apply a thin film of high-efficiency weapon grease to the outer operational tracks of your separate bolt carrier group and charging handle block. 3. Insert the charging handle into the upper receiver tracking slots, drop the bolt carrier array into the cavity, and slide the assembly completely forward into lockup battery. 4. Lay the completed upper receiver structure onto your host lower receiver frame, aligning the front pivot pin holes first. 5. Push the lower receiver\'s front pivot pin horizontally through the upper yoke, pivot the upper down flush, and pop the rear takedown pin home. 6. Pull the charging handle rearward manually several times to verify buttery smooth action cycling and absolute extraction alignment before choosing optics downrange.*
