Ive looked at a similar one awhile back ago. Heres what you need to read and consider (its in the description)
"This CO2 pistol is recommended for TARGET-shooting use only, as it is extremely powerful"
Ive heard stories of people getting these into vanguard and causing serious Injuries. So keep that in mind if you decide to purchase something thats to high fps for the fields. Dont be that guy who brings it to a game and injures someone with it. People would get pissed if you had something shooting hot, especially me... i would rather get something he could use at a game. Hoped this helped.
