Andro Corp Industries Bravo .300 Blackout Complete Upper Receiver - 10" 4150 CMV Barrel, 9" M-LOK Free-Float Handguard, Pistol-Length Gas System, Forged 7075-T6 Receiver, Matte Black Anodized Finish - U30010ML / 736684144791
Product Description
Building a high-performance tactical pistol, staging an agile hog-hunting package, or configuring a dedicated suppressed short-barreled rifle (SBR) requires an upper assembly engineered with a reliable gas pressure matrix. Attempting to run large-bore micro-propellant cartridges through long, sub-optimal gas pathways drops terminal chamber pressure rapidly, triggering continuous short-stroke failures with subsonic hunting loads on your bench. The **Andro Corp Industries® Bravo 10" .300 Blackout M-LOK Upper Receiver (U30010ML / 736684144791)** completely flatlines these cycling and interface bottlenecks, supplying a factory-headspaced **compact barreled upper package** centered around a perfectly tuned pistol-length gas layout.
Proudly assembled, calibrated, and live-fire tested in the United States by Andro Corp Industries, this duty-grade upper receiver is built from a forged **7075-T6 aircraft aluminum alloy** shell treated with a deep, non-reflective Mil-Spec Type III hard-coat anodized layer. Nestled at the mechanical center of the block is a premium **10-inch 4150 Chrome Moly Vanadium (CMV) steel barrel** configured with a versatile 1:8 twist rate and an ultra-durable liquid melonite coat. Operating on a robust **pistol-length gas pathway**, it yields smooth, predictable bolt cycling whether running unsuppressed supersonic target ammunition or high-backpressure subsonic silencer setups. Wrapped in a low-profile **9-inch free-float aluminum M-LOK handguard** with a continuous top Picatinny rail, this turn-key tactical assembly upgrades your custom compact rifle or pistol 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 U30010ML complete barreled upper assembly arrives workspace ready, containing the pre-machined 7075 upper shell, forward assist assembly, spring-loaded port cover door, 10" melonited barrel, low-profile gas block, pistol-length gas tube, 9" 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 configurations**. *BCG, Charging Handle, and NFA 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. Furthermore, attaching this 10-inch short-barreled upper package to a standard lower receiver configured with a traditional buttstock creates an SBR, which is subject to strict **NFA registration and tax stamp frameworks** under federal ATF guidelines. Ensure your configuration utilizes a legal pistol stabilizing brace or possesses an approved Form 1 before assembly. 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 layer of high-efficiency weapon grease to the outer operational tracks of your separate bolt carrier group and charging handle. 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.*
