Definately and Fast Hopper. atleast 15-17 BPS if your planning to go AUTO or Fast on semi eyes off.
Longer barrel, not necesary but better then a 12''. make the gun quieter
-Its looks L33T
-Fast keep up with it
-as durable as your gunna get
-Loose handel/grip, you'll see
-No eyes on auto obvious
-VERY LOUD. get a longer barrel, make it quiet not give yourself away
-Expensive (got mine off ebay. amazon good too)
-Better off HPA but i got CO2
awesome gun. recomend it to anyone. dont get it if your new. kinda hard to explain. you have to know PB markers?
