KWA ATP-SE Full Metal Automatic NS2 Gas Blowback Airsoft Pistol

The New KWA ATP-SE AUTO is the latest version of KWA's highly sought after ATP (Adaptive Training Pistol), now featuring a threaded outer barrel! This allows you to screw on aftermarket barrel extensions and mock suppressors with ease. Utilizing KWA's NS2 Gas Blowback System, this airsoft pistol seamlessly blends performance with a unique and ergonomic design. The ATP AUTO is one of the most anticipated Gas blowback pistols to be released by KWA, and it definitely lives up to its expectations! This pistol is lightweight, fast shooting, and extremely accurate. Due to the slide's lightweight design and the superior NS2 gas system, this pistol is extremely gas efficient and can easily fire a full magazine in full auto without the normal sluggishness of other full auto gas blowback pistols. The ATP-SE AUTO's disassembly is similar to KWA's M series gas blowback pistols.

NOTE: The first photo above shows the most latest version of the KWA ATP Airsoft Pistol.

The external design and construction quality of the KWA ATP AUTO is excellent. Its composite polymer lower receiver and stipled grip provides an amazing non-slip surface and comfortable feel. The pistol's grip features interchangeable back straps, which insert easily and quickly convert the grip to fit any user's hand. Another added feature of the KWA ATP AUTO is its bottom accessory rail, which allows you to attach a wide variety of tactical accessories. The slide is completely constructed of a metal alloy, and features rear slide serrations for rapid loading. Another interesting feature of the ATP AUTO are its three dot combat sights, which makes it easy to quickly acquire targets in close quarters combat situations.

Overall, the KWA NS2 ATP AUTO not only improves the functionality of the original ATP, but also stands out amongst other fully automatic gas blowback pistols as a uniquely designed, fast shooting, and extremely accurate airsoft pistol. Don't miss out on the revolutionary KWA ATP AUTO, because these are sure to sell out quickly!
