Yes.
yes, also has a couple other modes
Yes, it can if you look on youtube there are various videos that show people shooting it
You should use HPA with a Proto SLG.
Proto SLG all the way. Stay away from the spyders.
DP G4 is definetly the way to go. The proto slg can't shoot as fast, isn't as light, and has way too many problems. The G3 was an amazing gun and all they did with the g4 is fixed the few knicks with it and the G3 was a better gun than the SLG. Plus if you ever do have a problem with the G4 the customer service is amazing. I love my G4 get it now!

The threads are autococker threads. All proto and dye guns have autococker threads.
Yes, as long as it is Auto-cocker threaded, any barrel will fit.
Sadly no. The Ultralight board will only work on the Ultralight frame. If you are looking for a good board though, maybe look into virtue boards.
Although both is decent for the price, the SLG is better. If you have money for the SLG, go for it, otherwise the Piranha GTI is good enough.
