Spyder fenix acs with upgraded springs, psycho ballistics drop forward, and a 14in 32 degrees whisper barrel
definitely get a new barrel
Battery wares out after a while
This is a very good gun. With the new barrel it is great. It doesn't break balls. I got it for a very good deal, 60 dollars on ebay and it was well worth it. Also the drop forward is a very good upgrade to get. In my opinion given the chance you should definitely buy this gun.
