Also available in 17lb or 22lb. These ISMI Springs are made from a stainless alloy instead of 150 year old music wire.Every ISMI spring is heat treated, shot peened & stress relieved to enhance durability, consistency and reliability. ISMI is a contractor of the U.S. government and produces springs used in machine guns with incredibly high cycling rates. Also, the creator of ISMI springs obtained his knowledge from extensive research in the development of springs used in Indy car racing. In independent testing, ISMI spring have endured in excess of 100,000 compression cycles. We don’t recommend going that long between changes however. With an ISMI spring, practice routine maintenance and change it once a year.
