What is the best airsoft sniper rifle?

I recommend the KJW Mk.1 Carbine. http://www.airsoftpost.com/product_info.php?products_id=25038 Now first off you might think its cheap and plastic BUT its not. I own this thing for months and its still shooting great (as long as you do maintenance on it) Pros: Most powerfullest sniper I've ever seen. with propane its 500+ fps to even 600 fps on a really hot day. Its accurate, especially with .25grams and .30 grams. But for even more accuracy you can buy an extended barrell for it. Light and high mobility. Made of strong ABS plastic on outside while all metal on the insides Semi-automatic means higher rate of fire than springbolt snipers Cons: Only thing bad about it is the long trigger pull which can become a nuisance but shouldn't get in the way. For all its worth, its a great deal for a 90$ gun. Attach a scope, an extended barrel, a bipod, and you'll be ready to rape in the battle field.
