HUMA regulator for Daystate Renegade .22

Thank you, Mike! In case anyone wants to try (which probably isn't necessary), here is the "How" I got from a technician at AoA:

Take the action out of the stock, under RENEGADE / SWP there might be a plastic cover covering the hammer system. if there, remove so you can see the hammer. COCK THE RIFLE, take a 3mm allen wrench and enter through the back block plug and turn until you can see a 2mm allen screw. To adjust the stroke length you will need to loosen the 2mm allen screw then turn the 3mm allen wrench (Clockwise to increase the velocity / Counter Clockwise to decrease) tighten the 2mm screw when finished with the adjustment.

Good shooting!
