Variable FPS Mod Kit (GHK AK)

NOTE: 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. No tap set required! Why: You own a GHK AK, which shoots too hot for your field and you need to lower the FPS. At the same time you don’t want to permanently be stuck with a single FPS choice, and need to be able to dial in the FPS depending on the field you play at. What does it do, and how: Screwing a small set-screw further into the stock nozzle constricts the airflow to the barrel, thus reducing FPS. Screwing the set-screw in & out will allow you to tailor your FPS for your specific field.NOTE: You will not be able to increase FPS more than whatever the stock nozzle can achieve.
