This gun rocks!!!!!!!!!!!!it is extremly accurate and has very far range. When i got it the first game i played i kicked every ones butts!!!!I was just a newbie too. When i went to california we played with pros and they had angles and crap.My bro has the same gun and he did really good!i did ok but of course since he is older than me he did better but still.If you really want to rack up the kills that i suggest this gun.
I got this gun on x mas and when i tried it out the co2 froze up the gun and i thought it was the gun!it turned out that when it got warm it worked perfecly and i ruled all.So if you want to play in the freezing cold then get compressed air and you will do fine but i dont like to play in the cold any way.
The only upgrade you will need is if you want to play in the freezing cold then you need a commpressed air adaptor. but other than that you dont need it.I think this gun is worth every penny and it comes with a case.it is a really good gun for its price.
And if you have 200 bucks to spend then i say you should get it.
