With the imminent release of Echo1 RedStar CSR Semi Auto AEG Airsoft Sniper Rifle on Monday, Echo1 USA released a video which will walk you through the finer details of this semi-auto sniper AEG. One thing that would interest you is the four gear train system that will allow the rifle to shoot over 500fps. That's out of the box and no need for upgrades to achieve that.

"Echo1USA has just posted a new video highlighting all the new features of the Echo1 RedStar CSR Semi Auto sniper airsoft rifle. These features include a reinforced four gear mech box, 685mm inner barrel, two hi-cap magazines, and battery & charger included. You can check out the new video on the official Echo1 YouTube video channel. The new RedStar CSR ships on June 11, 2012."
