IMPORTANT NOTE - As was pointed out, the head can be a bit loose when you put the head in. However, this is only the case if you stop at the first "click". Due to the limitations of the design caused by minimum wall thickness and maximum size allowed by the Nightbeat toy, the sides have to be hollow. This means the head has wiggle room UNLESS you push it in far enough to go into the square hole at the bottom of the adapter. This will feel like a second "click". For best results, push it in all the way. I'm removing the listing for the "collared" version of this adapter. Since this link got shared more, I'm updating the model here for the collared version. It works WAY better than the original design. The original was limited in which Titan Masters could fit properly, but this one is much more universal. I've not updated all the pics, just added a pic of the collared version installed. Honestly, I think black works best. The hole is bigger so they go in easier, but there are tabs on the sides to hold the head. I've removed the Hi-def acrylite as an option. Someone reported that it worked, but ended up breaking. I guess it's not flexible enough. This adapter is designed to turn the Generations Nightbeat toy ( as well as any repaints ) into a Titan Master compatible toy. I've got installation instructions pictured that are of the Go-Shooter version of the toy using the Loudmouth head. I've also designed a rifle for Nightbeat that the Titan Masters can sit in when attached to the side of the car.
