leave it be, play with it first mate, you havent even played with it yet. Just leave off till you have played with it once, and you'll most proably find it need nothing doing to it
Possible things you could invest in:
Eclipse (or other) Front Bottle Mount - this allows you to run any reg with a standard threaded ASA instead of the standard one. Personally i find the standard one ok but some people prefer to replace it to help consistency and also to provide a longer area to grip. (www.g3paintball.com have a couple)
LPR Reg Tool - there's a special tool to help you set your Low Pressure Reg to the right level. Basically it's a gauge that screws into the back of the gun where the ram normally goes. Whack out the ram, whack in the tool, adjust pressure - piece of piss. It's still possible to tweak the gun without it but it is more accurate.
