ZCI M120 Spring


These ZCI springs come in stiffnesses from M80 up to M150. Maintaining ZCI's trend of maximizing performance per cost these are just bare springs, removing the cost of packaging and adding shipped expense. No FPS estimate is given because as with all spring ratings there are so many other factors that effect FPS the given value would be almost arbitrary.

A mid-range spring ideal for general mid to high FPS (350-400) field setups and short stroked low FPS CQB setups.
