The K25 spring is another legacy modding spring used in many blasters. These are virtually identical to the original K25 from McMaster, except I had these custom-ordered, and they have flat/squared-off ends for a better install experience...

Perfect for the purpose

Bought this for my Caliburn C4. Wanted to dial it in a bit more with the Shearforce BCAR I’m using. It definitely helped!

My shop would fail without K25 springs

I've been buying about 300 of these a year and they're the best spring for high FPS half dart hobby blasters. Can we get another bulk tier at 100 springs ordered?
