Based off the fantasy build done by Dave Merrill in 2017, https://www.recoilweb.com/the-pdw-that-never-was-car-15-model-n-23-131167.html .
Make yourself an awesome N23 clone build without the hassle of cutting down hand guards.
3D Printed using ASA for heat resistance and durability.
These Hand Guards DO NOT come with heat shields!
You should consider cutting down a set of heat shields from a skinny set of carbine hand guards. Provisions for heat shield mounting are designed into these hand guards.
The last picture shows what they look like with heat shields installed.
