Half-dart length APFSDS for Nerf blasters. It has two sabot pieces that form a loose seal with the barrel and then split off after exiting. The dart sits inside and takes a 2mm pin in the front to keep it stable.

This of for springers only!!! This will murder flywheels!

This is more of a joke, but shooting at cardboard/foam can be fun. Unlike others I've seen, this one should work in a magazine. 

DO NOT FIRE THIS IN THE GENERAL DIRECTION OF LIVING THINGS!! Even if you don't aim at them, there are still the sabot parts that fly randomly!

Prints best with a 0.2mm nozzle but works with 0.4 as well.

Have fun and don't die please.
