TOO SLOW?

USE THIS.

The Adventure Force Double Fire Quick Loader... I know, it's a long name, but it works. This is made for the AF Double Fire shotgun, though it might work on a few other Nerf blasters. I had to slide the insert around a little bit to make it less sticky. The insert is hard(ish) to get in, but once in, it won't come out (though I haven't REALLY tried to take it out). Best printed as is (without supports).

Hope this model makes your Nerf wars more fun! GOOD LUCK AND HAVE FUN!
