The K31 11" Spring is compatible with dozens of blasters. These are identical to the ones from McMaster, except I have had these custom ordered and they have flat/squared off ends for a better install experience. This means that even after cutting the spring you will have one flat end, making your install easier!
FEATURES: • K31spring with squared/flat ends
SPECS: • Material: Made in the USA of USA spring-tempered steel • Dimensions: 11" long / 0.781" OD / 0.062" Wire
