AR-15 Castle Nut Wrench

thingiverse

A compact castle nut wrench designed for AR-15 style rifles is ideal for its portability. The tool can be easily made by cutting from steel using a laser cutter, although any material would suffice due to the minimal pressure required. This design has received a significant amount of attention and appreciation. I've uploaded photos showcasing my version, which was crafted from 3/16" cold-rolled steel utilizing an Amada laser cutter's capabilities.
