[Set] CM.708-U Upgraded Version 570 FPS - Black [CYMA] + RifleScope Victoptics SOI 4-12X40 [Vector Optics]

Pros:
Look and build quality are spot on.
With the factory-upgraded internals, it hops 0.40g BBs with ease.
At 70 meters, 8 out of 10 shots land within a 10 cm grouping.
Cons:
Very front-heavy, especially if you use a bipod. If you're shooting standing up or crouching, your arm gets tired really fast.
The dual-lever hop-up chamber is a bit tricky and finicky to adjust. Since it's a powerful rifle, the hop-up screws tend to back out after a few shots—a little teflon tape fixes this right up.
Due to the hybrid design, not many hop-up buckings are compatible with it; I stuck with the stock one. Standard Macaron or Monster buckings didn't work out.
Reloading/changing magazines is a bit awkward at first, but once you get the hang of it, it’s smooth sailing.
Overall:
A solid, brutal-looking rifle. Quite accurate with great range. Despite the downsides, it's an enjoyable rifle with great value for money.

Solid construction, good quality. Accurate ( tested on 40 meters) hop adjustment is a bit of hassle but once it's set for specific bb weight it's fine. Gun is on the heavy side, helps with aiming but gets tiring after carrying for a few hours. Charging handle can twist off, added a counter nut to prevent it.

it's not good, it sticks and every fifth ball gets stuck.. the magazines are very poorly assembled, they also get stuck just like on the replica cyma 707. that big magazine is not a magazine, but a small magazine that is very difficult
take it out when you change the magazines, they are very badly assembled
rifle

It ran extremly well in an airsoft game had no problem it’s just a little hard to reload and the trigger is extremly stiff but it shot at a good distance and the looks are also extremly good you will barley tell the difference between and actual one
