Worker 5KG Doublestrike Spring
This spring works great in this Nerf gun, defiantly gives it more power than before. I use this Nerf gun in every Nerf war, it gets the job done!
Modding the double strike is very simple and upgrading the spring is a must. This 5k spring packs the right amount of punch. Easy enough to still prime with your thumb and a very noticeable increase in performance. Luke and co deliver Ed on time as always.
Great spring to do a nice little upgrade for a friends Christmas gift!
