OOD K31 1.6 x 280mm Spring with Squared Ends

The K31 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 installation easier!
