Power up your blaster with this Worker 22kg upgrade spring.  Compatible with the Longshot CS-6 and the Zombiestrike Longshot CS-12. Provide serious firepower to your blaster with this upgrade spring.

This is an advanced spring.  Only purchase this spring if you are an experienced modder.  Catastrophic blaster failure (ie you will break it) will occur if your blaster is not strengthened.  Sufficient blaster reinforcement is needed with use of this spring. 

This 22kg spring has been designed to use with reinforced, strengthened Longshots.  Get the max fps out of your blaster whist retaining a manageable priming force.  To make full use and performance out of this spring you will need a sealed breech of some kind/make.  Comes included with silicone buffer pad, upgraded catch spring.

Make sure you re-install the stock 'prime indication bar'.  This both serves as a stopper when priming back, and also holds the catch spring from popping out of place.

Expectations.  Variables considered, depends on darts used (quality/condition), Blaster condition, breech used, lubrication and how well it is been maintained, seal etc.
Stock Longshot = Don't use with stock longshot (use our 8kg longshot spring)
Sealed breech (pusher kit)= Not tried this spring but should be pushing up to 250fps with the right setup.
Sealed breech (brass breech)= Not tried this spring but should be pushing up to 250fps with the right setup.

Blaster compatibility:  Zombiestrike Longshot CS-12 and Longshot CS-6.
