I know of a workaround that some retailers do mate, you will need a 0.5mm drill bit and you need to drill two or three holes in the air nozzle tip, basically it creates a very smal imbalance in the airflow but will bring your fps down to a consistent 340-350fps

For the love of god don't do that, clip a coil or two off of the M90, re-bend it and grind it flat and you should be good to go buddy.
