Everything. It looks cool, performs awesome, awesomely made parts.
I doubt this thing will break within the next 10 years. The best thing is that i whacked an autococker with it.
It loks graet and works awesome so buy it.
Stock barrel is fairly good (above average)
Weaknesses:
costomer service. thaty doesnt really matter though. and it didnt come with the x-barel. they said the x-barrel was defective or something so they didnt want to dissapoint us.
Conclusion:
Great gun performs well and looks good. id say buy it.
