This is a very tight fitting Nerf vertical grip attachment usable on N-Strike rails, and clicks in with quite a bit of force needed to pull out. (Depends on the Nerf Blaster). This attachment is designed for the bottom rails. Please note once again, this only works on N-Strike rails commonly found on most Nerf blasters. If your unsure if your Nerf blaster has one search it up and make sure it's N-Strike! Note this does not help you aim, just for cosmetics. Certain Nerf blasters have bottom rails wider, this attachment has been found to work best on Ultra Nerf blasters. If you are planning to use this on the Elite Nerf Turbine, it will not work due to the bottom rail on that blaster being to wide. 

If you want to build your own attachment from scratch, or want to test if your gun is compatible with this attachment, use this model: [https://makerworld.com/en/models/1023672#profileId-1005480](https://makerworld.com/en/models/1023672#profileId-1005480)
