Worker 7kg spring upgrade for Retaliator.
This is the best bang of your buck spring upgrade for your Retaliator!
The package includes a 7kg main spring, a better O-ring for the breech, a silicone padding for the high impact points within the blaster such as the plunger tube and plunger rod.
This spring can push a stock Retaliator blaster to 90FPS and more with the Air Restrictor in. I have personally tuned a Retaliator with this spring and it can do more than 100fps easy.
PS: FPS chrono test is done with Hasbro Elite Dart.
