Welcome to ak-builder.com!
Here is a tool that we have been using to demill and populate our parts kits.
This is made to support the AKM gas block and front sight while removing or installing the pins. The block is anodized and then laser engraved showing how the gas block or sight sits on the block. These are made from 6061 T6 aluminum then black anodized. This also will work with Polish Tantals and AK74s.
