I had a lot of fun designing this new head for my nerf Slingfire. Its a custom barrel for the slingfire I designed to look like a dragon with battle scars and it also includes a sling mount near the back. As a bonus, I also featured side tubes to store any extra nerf darts just for fun even though this blaster uses magazines.(they look cool though)
Notes: some features can be very spikey so you may want to dull the edges before giving it to anyone so they don't cut themselves by accident.
The fit between the barrel and the blaster is very tight so it may take a little bit of patience before you can get it in place. The clip on the bottom can fit via friction but I highly advise using adhesives to keep it in place.
