I have a CYMA SR16 sport E3 full metal Has a Firefield holo optic I can include for 30$ more, Front hand grip, it does have the cover for the back of the stock, it’s only been used a handful of times and it’s an amazing Gun, I just travel a lot for work and barely have the time to use it. Very well maintained and it comes with 7.4 lipo batteries, and 1 Hicap Wind up magazine.
