Cyma 040c with 450 mm Prometheus 6.03 tightbore , black modify ryosoku flat hop nub and bucking (black hard type);with eBay no sanding rhop patch in barrel window shooting roughly around 1.63 ish joules, shoots pretty darn far and accurate but I will say that to make proper hop up adjustments you only need very miniscule microscopic adjustments otherwise you'll be prone to overhop because with how it's set up currently the hop up is very sensitive so just teeny adjustments are needed for proper hop. The only issues with it is when I was putting the gearbox back in the body I chipped off part of the trigger and I did take off part of the selector on the gearbox to switch it to full auto so it's basically semi-auto only but otherwise the internals of the gearbox (I believe it's an echo 1 red star gearbox to be exact) are in excellent condition. I'm asking for $150 + $25 shipping price firm. Inbox me for my cell#. Will also include 2 tenergy 1600 mah 1600mah stick battery with the aeg and a titan digital lipo charger. That's 125$ for the aeg with RDS and scope mount , 2 stick batteries and an additional 25$ for the titan digital charger as a package deal grand total cost of 150$.
