Respuesta a "Darts fall out of gunbarrel"Simple. The darts are worn out. Purchase some off-brands like Waffles or Accufakes prolly on Amazon
Respuesta a "How do I fix a brand new Nerf Modulus Regulator that is not firing?"Whenever your blaster has trouble shooting, it's either jammed or there's something wrong with the mechanics. Make sure you use the correct type of ammo that has the correct length. If that doesn't resolve the issue, unscrew and open up your blaster to look for the parts that have problems with. There are plenty of photos online that show the blaster when disassembled. Try to follow those pictures and rearrange the parts. Also, I recommend you to join Nerf Amino. It is a Platform where many Nerfers gather together and discuss about Nerf. You can contact some of the modders there and they could probably help you with that.
