This is a barrel extension/mod that lets you press a brass barrel for standard size Nerf darts into a Bigshot Nerf pistol. The new brass barrel runs from the end of the print through the length of the gun barrel and is sealed at the bottom.
The end of the brass barrel is wrapped with electrical tape to form an airtight seal into the original dart barrel, and if you're careful you can size the tape wrapping to make the barrel mod removable.
There's some other trimming done to the gun as you can see in the photo, however there are no required modifications to make the extended barrel or printed barrel mod fit.
