PeleusTech NFstrike Spring Upgrade, 12KG Modified Steel Spring for Nerf N-Strike Elite AccuStrike RaptorStrike

It's working great. I wanted to have a little fun with the NERF gun so I got this and I'm not disappointed. It has more power and flies straighter but I'm not seeing much more distance.

Ok

It runs great in my raptorstrike...a bit of a warning though there is a crap load of screws in the gun. Worth the performance and I recommend putting an upgraded catch in with it so it runs a little better but it does run okay without it

the 12k spring is too stiff and did not work. after installation the spring woukd not compress enough to prine for firing. after removal the spring looked bent and misshapen. not a good product.

Super springy. Worked great in my nerf gun.

This is not the spring for centurion! Spring is way too small! Too stiff as well.
