SEE INSTRUCTIONS BELOW! IMPORTANT: I AM NOT RESPONSIBLE IF YOU DECIDE TO MODIFY YOUR EQUIPMENT. YOU MAY VOID ANY WARRANTY BY FOLLOWING THIS TUTORIAL!!! Overview: Modify a stock GHK AK nozzle to allow for on-the-fly FPS adjustment without the need for a tap set. Why: You own a GHK AK that shoots too hot, requiring lower FPS in your field, but you don't want to be stuck with a single FPS choice. Instead, you need to dial in the FPS depending on the field you play at. What it does and how: Screwing a small set-screw further into the stock nozzle constricts airflow to the barrel, reducing FPS. By screwing the set-screw in or out, you can tailor your FPS for your specific field. However, you won't be able to increase FPS beyond what the stock nozzle could achieve.
