The Super Nova has all the same great features of the Nova 700, plus a 12" barrel with ported foregrip, Vertical feed body, 45 grip with bottomline pressure regulator, removable sight rail, and adjustable pneumatic trigger.
The Airstar Super Nova is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
I have owend this gun for about a year, I love it. It is really acurate. The trigger pull is AMAZING, virtualy no force required and only moves close to 3 mm. Balls fly straight and far. I mean really far. And the balls dont get all screwy and start doign loop d loops at distance like other guns I have shot.
Not much. The company went out of buisness so parts can be hard to get, but this gun is fully pneumatic and has no moving parts on the inside so you dont have to worry about replacing anything but o-rings.
So I would say its the most acurate gun, out of the box I have ever shot, it has a upgrade barrrel I have heard good things about but not used so I cant say for sure. REcomend buying if you can get one. I payed 280 for mine on ebay and it was well worth the money.
I have this gun, i got it about 2 years ago and it still runs like new. This is the best gun i have laid my hands on since i have begun playing. Keep in mind i haven't used many other guns. This gun is a totally pneumatic marker and is the only gun that's pneumatic besides the Epic. All in all i beleive this gun is a conversations starter as well as a great gun all around. I have loved this gun since i bought it. It hasn't given me any problems in the 2 years i have had it!!! This is one of the most accurate guns i have used and it has straight rifling.
Not much besides the company that manufactured this gun went out of buisness and u can't get very few upgrades. This gun is like Fort Knox to get into, in other words it is Freaking tough to get into, but on the other hand u really don't need to get into it because this gun won't give u ANY problems.
This gun is well worth all the money, i wouldn't recomend it for newbies but for the tourney warrior this thing is great. It is very dependable and is a good friend on the field!
