Did you make a lower that accepts glock mags?
Yes. I posted most of the pics on the FB group. Some of the pics are on an old instagram, thekettlebellgunsmith. Sorry to say, it's a one-off project. I do it for a hobby. Only made one and not planning to sell it. Reached out to Manticore arms to see if they wanted any of the measurements and don't believe they were interested at the time.
Wow, this seems like a much better project than a bullpup conversion, from a consumer interest standpoint... People would jump at the opportunity to buy a simple lower that allows for Glock mags.
