Shoots and functions as it should. Has upgraded hopup and bucking. The hopup is guillotine and allows you to adjust tension tdc via the hex screw. The bucking is a 70 degree maple leaf. The nozzle was also replaced with a TNT high flow nozzle which shoots around 1.45-1.6 joules depending on how hot it is outside with propane. Externally I changed the handguard to a B-11 and changed out the stock as well. I also swapped the grip with a rs magpul one. I have an optic mount as well if you want it. It comes with 1 green gas magazine that holds gas, however the main spring needs to be replaced as it doesn’t have much tension anymore and doesn’t always push bbs flush with the top of the mag, causing jams. I can send a video of it firing with my drum mag to show it functions.
