"Decent gun, accurate, very realistic, but this gun jams every single day I use it. I've upgraded the internal hop-up and bucking and it still jams. I would return this if it still was within the 40 days, sadly I can't.

Overall good gun when it work, but it's kinda a 50/50 on jamming, after cleaning it properly.
