Automatic Roll Pin Punch... I think I invented it? Has anyone ever seen one?

[EDN9HT]

Hello everyone, I was looking for a solution to an issue I had while installing a roll pin in a gun and this is what I came up with. I searched for it online but couldn't find anything like it so I figured out how to make one cheap and easy. Thought about trying to sell the idea to a tool manufacturer but figured they would just steal they idea anyway so I decided to share it with all for free. And it may already exist. So if you have seen anything like it please let me know. Just curious...

Here are links to my use for the tool and how I made it. Hope someone likes or benefits from it!

Has anyone seen anything similar on the market?

Thanks!
