ACTION ARMY Black Mamba CNC Upper Receiver Kit A for AAP-01 GBB Airsoft

Full metal. Comes with upper and lower rail. No apparent design and/or quality flaw. Fits vanilla lower quite well. Flash hider part can be detached and replaced with something else. Some might argue buying separate rails are better choice. You make the choice. I chose this because it looked cool and had both rails built in.

Superb replica of the Volquartsen Black Mamba for Ruger 22/45. Perfect addition with a 6" inner barrel and the ACTION ARMY AAP-01 Wheel Adjusted Hop-Up Chamber inside to get incredible performance.

Makes the aap01 look like a different gun

worth the price 100%, gives the gun a much needed update in terms of looks and makes it feel way more solid. The metal rails engraved in the slide are also a huge plus.
