I would have to disagree on this one. Sure Sniping "can" be one of the most expensive roles for airsoft...in the spring gun area. However I have researched many teams and find that most are moving to the gas-powered area.
I picked up a KJW M700P sniper rifle for 230.00 dollars. Stock and with the restrictor removed, it fires a 0.36 @512.00FPS. Not bad for a clone rifle.
Gas rifles aren't consistent, and are also variable depending on weather conditions. They shoot hard, sure, but without running a regulator and a constant-air source, you're probably not going to get the required accuracy shot after shot to warrant carrying one on the field over an upgraded AEG. Besides, yours is a little hot for most field use.
Most players tend to forget that the "sniper" role in airsoft isn't about taking the "one shot, one kill" mentality, it's more about recon, surveillance, and proper use as a hidden force-multiplier.
