KWA has engineered airsoft rifles for over 25 years, and every rifle here is built by KWA. Gas blowback rifles like the LM4D, AKG and Radian Model 1 cycle the bolt with every shot. AEG Variable rifles like the KO series and Ronin T6 run on a battery and let you adjust FPS to fit your field. AEG Recoil rifles add KWA’s Kinetic Feedback System electronic recoil. Not sure which system fits you? Read GBB vs AEG. Each rifle page lists exactly what comes in the box and which magazines it takes, and parts and manuals for every model are on Part Finder & Diagram. Built to Run, Backed by KWA.
