Spring recommendations for specific guns are not always the best option. Several springs may be recommended for a gun but what is reguired is one that is the best fit inside the piston. If there is too much gap between the piston and spring a severe twang can be the result so beware and always measure the piston inner diameter before ordering a spring.
