CRESCENT goes over the Yanhu RUGER Mk.IV Ruger Mk. 4 airsoft pistol, whose real steel inspiration is a popular choice for beginner shooters in the US due to its simple design. The airsoft model mimics the look of the 22/45 Lite race custom version, featuring a CNC aluminum upper receiver, a polymer lower frame, and a custom charging handle for easier use. They list its features like the 14mm threaded muzzle and the optional BB-gun conversion kit, concluding that while there are minor cosmetic differences from the original, the gun holds significance as the first airsoft version of the Ruger Mk. 4 and is suitable for casual shooting.
