The Black Mamba Upper Receiver Kit from Action Army Company is a precision-engineered aluminum upgrade designed for the AAP-01 Assassin Pistol series. Crafted through CNC machining, the kit replaces the original housing and outer barrel, enhancing both fit and durability. Practical 21mm rails on the upper and lower sides accommodate accessories, while the adjustable rear sport sight can be removed for aftermarket folding stock installation. The distinctive CNC-machined compensator attaches securely with a 14mm left-hand thread (CCW), offering customization options. Designed exclusively for the AAP-01 GBB Pistol series, the Black Mamba kit presents a functional and aesthetic enhancement.

INTERNATIONAL ORDERS
Because the UK has now left the EU, all items on orders for delivery outside the UK purchased from us do not include VAT, so you will likely be asked to pay VAT and duties at your local rate when importing.
Please note, it is the responsibility of the purchaser to ensure the legality of importation into their own country. If goods are seized, destroyed, damaged through inspection or confiscation in any instance, we accept no responsibility and will offer no form of refund, replacement or credit. If the goods are returned to us by the seizing authority we will be able to refund you for the payment of the goods minus any shipping costs, fines, fees, or charges imposed by that authority for handling the return of the goods. We will issue any refunds only when the products are received and checked by us.
