Like I said in my guide to airsoft you really have to pick this yourself. Although the gun doesn't make or break the sniper ( a quote from airsoft sniper.com, check it out! ) it is still nice to have a decent gun. A sniper rifle should be over 400 FPS and should be accurate at about 200-250 feet. It could also come in handy to have a scope ( for accurate aiming ) and a bipod ( to steady your aim).
