Zombie Strike Sledgefire Spring (80 FPS)
Zombie Strike Sledgefire Spring (80 FPS)
PRODUCT DESCRIPTION:
The Zombie Strike Sledgefire Spring is a custom cut spring from a K26 that offers a roughly 80FPS average compared to the stock average of 60FPS.
Difficult install on the spring. It is significantly longer than the stock spring so you’ll need to compress it a lot to put it back in while holding the levers in place on their anchors. Unfortunately, due to insufficient priming notches, we weren’t able to get any higher than 80FPS with just a spring upgrade so consider removing the air stops and adding in custom PVC barrels for increased air compression and single shots.
FEATURES:
• Hard difficulty on installation
• One end flat, one end cut, About 110mm or 14 coils in length
• Around 80FPS
• Custom made compression spring
• Material: Made in the USA of USA spring-tempered steel

It was a little tricky to install but works great. Easy to prime and great range for a shotgun excellent product.
Gave a little added kick to my double strike, can still be one hand primed, fit great as well, no complaints
