I'm not sure how well an Airmax 30 will fit the 510 as never had the chance to own one. I have had one on a Daystate Wolverine where the mag fits in from the left. This was with medium mounts. The way I got around the side wheel getting in the way was to fit a Rowan lever instead of the wheel. This way you could possibly use lower mounts and still have an easier way of adjusting the Parallex while fitting the mag in from the left.
