"Great gun it looks and feels amazing they can keep up with guns in a lot higher price range works great definitely recommend to any new players For anyone who just wants a cheap gun that’s gonna last you a long time

"This gun is great, but everything has its short comings.
-Full metal receiver and hand guard, only polymer part is stock and pistol grip
-Long inner barrel for reaching out long distances
-14 mm negative threads for a tracer or suppressor
-Charging handle reveals hop up behind bolt cover
-Shoots about 335 with .25
-Mostly metal internals, including spring guide and all gears. Big plus for high power builds

-No mosfet, so running 11.1 may result in ruined trigger connectors
-No easy access to spring, (I’m a tech so not a big deal but some people don’t want to crack a gearbox)

Not many complaints, so go for it. You’ll not regret it, this gun is so open to upgrades. I’ve put in a Gate Aster V2, Quantum Trigger, 13:1 SHS gears, a SHS high speed motor. This gun was good before these upgrades but now competes with P* and HIGH high end AEGs

"This is a sweet looking gun! It is heavy and feels like a real AR. It is completely full metal except the hand grip and the stock. The batteries fit well, and are easy to put in. The stock is adjustable. The mag wobbles in mine, and they sent me the right barrel length, but not the right mag well and main gun part. If you look at it, the 14 inch has no skull on the hand guard, and the 10 inches does. I received a 14 inch barrel I believe with a skull. I don’t really know what happened, but I’m fine with it. The stock magazine isn’t really amazing. I bought a hexmag to put in it, and it looks amazing.
10/10 recommend
Shoots hard, looks amazing.
Btw Cyma does an amazing job on looks. The box looks really nice and it is awesome to open. Love this gun!
I use .32s in this, and just put the hop up way up and it has a some serious range and it is very accurate!
I have yet to play it in a game, but I think it’s going to dominate the field

Shoots hard!
Full metal- like completely full metal not like some guns
Good rate of fire
Long range with the right bbs
Very accurate
Lots of rail space

Might be heavy to lug around all day I don’t know yet.
Hop-up is an enigma to adjust
Stock is hard to adjust. The piece you push on to lift the bolt needs to be pushed on on both sides. This leaves no hands to hold your gun. You can do it with one hand but it feels like the plastic might crack, I don’t know, I will update later if anything else happens
The manual takes a translated to read. Very hard to understand, but you can get the idea. Took me 10 minutes just to figure out how to put the hop up.
Big mag release, I keep bumping it and making the mag fall out.

The pros heavily out weigh the cons buy this gun NOW! You will never regret it! The only really big cons are the stock adjustments and the big magazine release.

It might seem cheap and you’ll get what you pay for, you don’t, you get a 300-400 dollar gun. It is an amazing deal! Buy it now. Even if it’s not on sale! I had mine in my cart and was contemplating buying it, and it went on sale for 50 dollars off! Bought it right then and there.
Tips- use .32s and get the 14 inch version. The short barrel ones don’t look realistic and the 14 inch is awesome looking.

Buy it!
