It would be 350fps which means that the BBs fired from the gun travel 350 feet per second.
G&G is a very reliable and good airsoft gun brand. In my opinion i think the G&G raider m4 series is good for anyone beginning airsoft or just wants more firepower.
Try the website for Trinity airsoft.
The fps depends on the brand and quality of the gun. If the gun is high powered spring it is probably at most 350 fps. Most likely the gun is less then this in the 275-315 range.

it depends on what you want to do. if you like airsoft then get an airsoft sniper. if you want a good paintball gun then DO NOT get one that looks like a military gun. in my opinion i would get a paintball gun. i would recommend $100 Azodin $250 proto rail $350 dangerous power G5 to me, these are the best starter guns. but before you buy a gun go to your local field and try it out to see if you like it.
You can buy a dboys or Lancertactical m4A1 for about that much, but they are not very good. they are prone to breaking and don't have great gearboxes. you are better looking at Airsoftgi.com custom's. make sure that the gun you buy is a full metal gun.
Depending on the company $90 to $175.
