I'd appreciate input on a pin guide/insertion tool that I've developed.
A potential backer mentioned that it would be great for reassembling his AR-15, and could have quite a few gunsmithing applications.
The mark 2 incorporates solvent resistant materials, improved layout, and an organizational feature.
I recognize that the layout and locations for pin insertion will vary significantly based on the model of the firearm.
If you have any design improvements or recommendations I'd really appreciate it.
