The AMP 160 High Performance AEG Spring is the perfect option if you are looking to upgrade your AEG's fps to between 535 and 560fps. It is also highly recommended that you upgrade plastic bushings and spring guide to metal bushings and spring guide if installing this product to help ensure that they do not break during use. Also, it would be wise to upgrade plastic pistons to polycarbonate piston; plastic piston heads to duracon piston heads; and standard gears to reinforced steel gears. Finally for best results a battery upgrade is also recommended and, just to be safe, upgrade the standard gearbox shell to a reinforced gearbox shell.
