Kronos 3.7" K26 Spring with squared ends

Dartzone Liberator Spring (120 FPS)

Regular price $5.00 Sale

NOTES FROM LUKE:
The Dartzone Liberator Spring is a custom made spring from a K25 that offers a roughly 120 FPS average compared to the stock average of 90 FPS. This mod is relatively easy and light enough for most ages on the prime. 

Super easy install. Just take off the shell and the plunger can be removed without taking anything else out. The custom cut K25 is slightly longer than the stock spring so you'll need a tiny bit of compression to get the screw back in but it shouldn't be too difficult. Also careful with the ammo load door to keep the tension spring on as it can pop out easily.

-One end flat, one end cut, About 150mm length
-Around 120FPS

SPECS:
