VFC Avalon gearbox pulled from Avalon Saber only fielded once. I personally built this SSG gearbox to perfection using new parts. Gears are shimmed perfectly. Excellent cylinder compression. Piston teeth precut by 1-1/2 for perfect AOE by Real Deal Airsoft. Adjustable nozzle to fit with any hop up. Gate Titan pre programmed with precocking on @ Safe/Semi/Full auto. Drop in ready to go. Shoots approximately 30RPS @ 400fps on 11.1v. -Gate Titan V2 standard ETU -SHS Rocket 13:1 gears -SHS Rocket High torque motor -SHS Rocket Tappet Plate -Real Deal Performance Piston Assembly 4.0 -Lonex full volume cylinder -Lonex cylinder head -Maxx Titanium adjustable nozzle -M120 spring -2 fps adjuster rings -VFC QRS motor grip -VFC ambidextrous selector gears -VFC anti rotation latch -VFC quick change spring guide -VFC bearings -VFC mock bolt lock latch -VFC trigger -VFC selector plate -sector delay chip reliable feeding at high rps I am also throwing in some extras left over from the build. These can be used to tweak the RPS and FPS of your build. You can modify the teeth count on the piston racks/use the ported piston and change out the springs to adjust RPS and FPS. The 18:1 gears can be used to return to approximately 22RPS. The ported cylinder is for shorter barrel builds to reduce air volume. This is everything you need to customize this gearbox to your preferences. -VFC 18:1 gears -VFC tappet plate, nozzle, cylinder, cylinder head, piston, and piston head -Lonex Piston (light weight) and Piston head -Prometheus ported Cylinder -SHS selector plate to use w different ETU -Guarder safety lever -SHS Japanese hard steel M130, M140, M150 AEG springs
