Not an FN57 pistol though it has some resemblance to it, SRC got its own design they call the Maverick and available at the KUI store. It weighs 750g, length is 213 mm, and comes with a 18+1 round metal gas magazine. It has reinforced plastic upper and lower frame and muzzle velocity is about 80-85m/s.

Well, well, somebody spotted a cute little gun coming out of Taiwan. Kui, an online retailer in Taiwan, have posted photos of the soon to be released WE Airsoft MPK Gas Blowback. Whilst not the first MP5K as it was first released by Maruzen, then cloned by WELL, nevertheless this version of WE Airsoft can be sustained due to the company's production capacity assuring that magazines and units are in enough quantities to satisfy players.
