Cyma 701 upgraded

I am selling a fully upgraded and improved replica from the manufacturer cyma.
The replica has a factory upgrade and modifications for stable and precise shooting. 
TDC, 70-degree rubber, additional piston guide and Teflon coated for ideal vacuum. It is cleaned and lubricated with Teflon grease after each use.
The muzzle data is about 575 fps with 0.20g or about 2.5j and measured with upgrades 2.8j with 0.43g. 
In reality, 0.43g is a little too much for it, maybe with heavier ones.
60-70 m straight shot.
There are 1000 shots in total.

The optics are 3-9x40.
The magazines are 2 x 50 shots
