jal3 Posted October 10, 2012 Report Share Posted October 10, 2012 Up for sale is 1 custom build Systema Revolution gearbox. It has been fitted with 9mm bearings and SHS 18:1 gears. It's a highly complicated customjob with tight tolerances. It's the 3 gear version that runs on normal motors. It's Safe-Semi-FA function. What you get: -Complete gearbox, M110 spring installed -Spare M130 spring -Spare M90 spring. -A whole bag of 2 extra gearboxes, who function as spare parts. Boards are broken i think. This unique box runs smooth as butter and shoots up to 125m/s with the M110 spring alone, depending on how airtight your hopup is. Recently serviced and everything is good. Ships from Denmark. New price is some 400£ + labor. And another 600£ for the spare boxes, so roughly 1000£ new price. Asking 140£ + shipping. This is perfect for UK market. If it shoots 105 you keep the spring in, if it shoots 125 you changed to M90 spring. It has a super short triggerpull and instant reaction like PTW. Link to post Share on other sites
