Mamba Type A Black Upper Receiver for AAP-01 (Action Army)

The Mamba CNC Upper Receiver Kit A is a CNC-machined upper receiver (bolt/external upper receiver) designed to replace the stock upper receiver of certain compatible airsoft guns (particularly the Action Army/AAP-01 series or compatible pistols/airsoft guns, depending on the model). Its purpose is to provide a more robust and modular chassis (Picatinny rails, accessory compatibility, etc.) and an improved aesthetic and tactical look.

Type: Complete CNC-machined upper receiver (metal/CNC aluminum)
Compatibility: Generally designed for the AAP-01 series (Action Army GBB pistols/compatible models)
Material: CNC-machined aluminum (or high-quality metal alloy) for durability and rigidity.

Finish: Black anodized finish — understated/tactical look.

Accessory Rails: Integrated top and bottom Picatinny rails — allow mounting of lights, lasers, optics, etc.

Sights & Aiming: Fiber optic front sight + adjustable rear sight (on some variants) for functional aiming without accessories.
Barrel Threading: 14mm CCW (counter-clockwise) threaded exit, allowing for the mounting of a suppressor, sound moderator, or external barrel if desired.

Installation: Drop-in – mounts directly in place of the original upper receiver without major modifications.

Maintenance: As with any CNC machined metal part, regular maintenance (cleaning, lubrication) is recommended to prevent corrosion or premature wear if exposed to the elements.

Airsoft Use Only: This kit is intended for replicas and is not approved for use as a real firearm.

The Mamba CNC Upper Receiver Kit A is well-suited for:
players looking to upgrade the durability of their replica,
those who want a modular platform (optics, laser, suppressor…),
custom/tactical/CQB builds or a realistic mil-sim look,
users looking for an aesthetic and functional upgrade without changing the entire replica.
