Adventure Force Nexus Pro Spring Spacer (+20 FPS)
If you are looking to stay relatively the same fps on a nexus after adding a scar.
The spacer worked perfect.
Spring spacers have been the #1 performance mod to springer blasters in this hobby for as long as I remember. A bit of hot glue and a good eyeball could go a long way in some of the old blasters. The times may have changed, but this easy mod hasn't. The Nexus Pro makes this too easy to install and a worthwhile upgrade for modders of every skill level. 1 screw, a drop-in part and boom: +20 to FPS and +100 XP to modding skill.
