KO:IRIS-4 AEG Variable
Here at KWA, we’ve pushed the limits of the airsoft industry with top-tier performance and purpose-driven innovation while maintaining our stance as a brand for every airsofter.
The KWA Originals Brand of airsoft guns focuses on a dynamic new approach to airsoft combat sports. Much like KWA’s release of the Ronin Series AEGs back in 2018, the KO Brand was devised to elevate airsoft as an industry and as a culture. KO is our pursuit to revitalize and reimagine what an airsoft gun is supposed to feel and look like while still paying homage and taking inspiration from classic weapon designs.
The next KWA guns to receive the special KO “polymerization”/treatment are the QRF Series, TK.45c and Ronin 47 AEGs. Each new KO release is a polymer port of their metal counterpart while shaving off almost a pound off from the original. These new KO releases feature the same upgrades as the KO:EVE-4 we announced in 2021 including the KO side charging handle and newly developed, high-strength polymer receiver body. Magazine compatibility will remain unchanged with each KO AEG able to accept their respective magazines from the original Ronins and QRF AEGs.
Internally, the new KO line shares the same 2.5+ adjustable FPS gearbox as the TK.45c, Ronin T6, QRF Mod Series, Ronin 47. Install your favorite aftermarket electronic trigger group and you have an ultra-responsive and lightweight polymer AEG with legendary KWA performance. Storm the Tactical League Battlegrounds by day and then adjust your FPS to lurk the plywood jungle at Project N1 by night.
