Hi capa with some upgrades which include: airsoft masterpiece slide, rail mount, cow cow short stroke, 150% recoil spring, flared magwell, and m4 mag adapter. I also have a gaurder enhanced nozzle and a 150% hammer spring which haven't been installed yet. The pistol is not actually $555, I'm just testing the water so send me offers. No lowballers. I'm not selling any parts separately.
