Wyhaq goes over the Koji Omega Nozzle made for the G&G LevAR... "In this video, I give my honest review on the G&G levar long omega nozzle v2 with tappet plate from koji kashima. This is a japanese adjustable flow nozzle. This nozzle is 2mm longer than the stock nozzle. I also show the process for installing guide how to the nozzle and tappet plate upgrade part and do a little bit of comparison in this honest review. I test if it works with short stroke kit as well as if it feeds properly. There are two versions of this nozzle, I chose the 4.0 mm bore full power. There is also a normal 3.2 mm bore power option."
