also dont buy from that page. ever Proairsoftsupplies is excellent. theres also firesupport, zeroone, patrolbase and a few others.
and if you are REALLY REALLY set on being a sniper, get the G&G CM16 and a scope (4x is standard for airsoft), then play like a sniper, only use it on semi and never fire rapidly. if this style suits you after a few games, you may consider a sniper rifle, in that case you got an excellent backup gun in your CM16. and if not, which is quite likely, you have not wasted your money on a gun you never going to use. Also keep in mind, if you want a sniper rifle that is actually better than an assault rifle (AEG), you're expected to splash a total of about a grand on the gun & upgrades.
