This gun is very accurate right out of the box I can fire mine extremely fast with no ball breaks. it is light wieght and easy to take apart. it does'nt need much lubing. and the price is competitve compare it to a tippmann that costs $150
and has no upgrades.
the barrel is vm style thread and the bolt hits hard enough to break a ball if you don't have enough gas in the gun
I would recommend this gun to anybody it is a great gun for only a $180 bucks it comes with an expansion chamber bob long bolt and a 10 inch barrel which shoots very accuarately.
