Hey, I have had my KJW M4 GBBR for about 6 months now, it works amazingly, but I really want to make it into a sniper of sorts. Does anyone have suggestions on what they would do to the gun to make this an effective sniper? I want to maximize its range and accuracy, and increase the recoil on it. I chrono'd it just this past week (when I finally got one) and it shot between 460 - 475 fps with .2 gram bb's. I would like the gun to shoot at about 370 fps with .4 to .43 gram bb's. I am also a big fan of the Magpul PTS PRS stock, and was wondering if the AEG version would fit this gun? Lastly does anyone have a list of rails that would fit on this gun with little to know modification? Thanks.
