Nine Ball Short Stroke Recoil Spring for Tokyo Marui HI-CAPA 5.1 Airsoft Pistols

"Since nobody else is doing a review I guess I will. This spring is called a "short stroke spring" because it's coils are closer together so when the spring compresses it is longer than a normal spring. This essentially short strokes your hi capa, about how much 2 recoil buffers would. The actual spring tension is probably closer to 120%, because when using my AIP 140% spring it was a bit more snappy. All in all its a cool concept and a great spring to use if you want to short stroke easily, but I will probably be sticking with my 140% spring though
