I was up pretty late and it came to me that anytime I use roll pins on a new AR build that have been removed from an old build, installation is always smooth and the pins stay securely in place in the new gun, even after thousands of rounds down range.
I realize that using already slightly squished pins is not standard and is probably frowned upon, but it truly seems to come without draw backs: I've never seen one walk out.
I decided that I want to make a jig that allows you to pass new roll pins through their correct sized holes before installing them into an AR, so that the build process can be made even easier (if you work on a lot of guns).
I know that this is something that I would want and would use, and it's very simple as it's just a not-very-thick slab of metal with holes bored through it with a press, and perhaps sitting atop a base so that the pins can be passed through easily and then fall onto your bench.
So I have 2 questions:
1) Are there any actual drawbacks to using the pre-used pins? I haven't been able to make one walk out of a rifle over a pretty long period and lots of use, but that's just my experience.
2) Would anyone else be interested in such a tool, or is it a more niche thing and only valuable to me?
It's also very possible that this post is retarded and that there is zero interest in such a tool, and that using used pins is a very very very bad idea. I just want some feelers before I make one for myself.
