OOD K25 2.0 x 280mm Spring with Squared Ends
OOD K25 2.0 x 280mm Spring with Squared Ends
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. This means that even after cutting the spring, you will have one flat end, making installation easier!

Insane power upgrade for any blaster that can take 280mm springs like this. I tried this spring combined with a Worker 1.8x270 spring in my Kunlun and with the stock barrel, it was averaging around 295 FPS with Sabre 1.3g t-darts. Dart Zone 1g bamboos were hitting around 335-345 FPS with the same setup. However, I'd strongly recommend upgrading your plunger rod and catch plate to the hardened steel version from Worker because of how hard this spring shoots.
Bought this for my Caliburn C4. Wanted to dial it in a bit more with the Shearforce BCAR I’m using. It definitely helped!
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?
Delivered just as described with above average packaging in a timely manner
Affordable, better deal then pre cut, I had enough for a Kronos and a Fury X from one spring.
(For anyone wondering the Kronos hits 120+ with just the spring, and the Fury X hits 250 with the spring and a 12 inch barrel.)
