First Ever Lock Bolt for the Milsig M17

I have designed a 3d printable Lock Bolt for the Milsig M17. This is something I have thought about ever since I got my M17 CQC. It’s not released yet. I have some tweaks I have to do. But it works. As you can see in the video, it works well. Once I tweak it to where I think it is good, I am going to put it up on Thingiverse for anyone to make. It is a single part that is bolted on, and done. No modifications to the marker to make it work. Just print. Assemble and install. DONE.
