I'm sure I remember seeing an AR stock somewhere that was tilted, I think it was on a HK416 on a video game maybe? I don't remember, I was just wondering if it would be a good/useful idea or some stupid video game stuff I can't forget. Or am I hallucinating?
loosen the castle nut, and you might be able to twist the buffer tube.According to google, this seems to be the solution to solving the very problem that you are wanting to create. I have no idea why anyone would intentionally twist the buffer tube. But to each their own
