I wanted to showcase this mod on the channel to help anyone having the same issues installing their select fire kit. Considering I didn't have these issues when installing the kit the first time, take this as a bit of an addition to my guide I made for the kit. I think there may be some tolerance issues in the print and/or the part qualities have lessened. This kits software is definitely different from the version I installed in subzero also. It turns on slightly different and I'm not sure that the set up is identical to the older version.This is pretty annoying since there's no hard directions besides the one on Taobao of an older version of this kit. I also think Daniel (Dart Dragon) did a great job painting this blaster. Definitely check out his channel link below, he has some cool Nerf gameplay footage. Hope you enjoyed the Nerf mod and select fire kit help.
PLEASE NOTE the black screw I used for the pusher mechanism did not work. If you're missing the screw like I was you will have to source one that will fit and not make contact with the pusher mechanism.
