Worker 7KG Rampage Spring Kit
It didn’t work, even when installed very carefully and properly. It was also very finicky when attempting to insert. Out Of Darts is great! Please buy a different spring though.
Just got this was expecting easy fit in. I don't know which step I did wrong, but the blaster just won't prime.
The spring was a little long and the upgraded catch spring didn’t work. Might work for other blasters though.
I used this spring in my nerf fortnite basr and it did a great job upgrading it without having any trouble.
