"This gun is so dope for anyone who loves Gundam or just wants a gun that’s gonna shoot hard.
by Ryan A. on 10/17/2021
"I did not buy this here but I did get it from someone selling it brand new unopened on the HopUp app and I’ve had it for about a month now and has been used in 3 game days, and I have to say I’m well impressed with this gun, it’s externally all polymer except the buffer tube and barrel, but despite being polymer it feels very solid and does not creak, internally it’s solid and shoots at a pretty high fps, trigger response is better than I expected (using 11.1v lipo), it shoots straight and consistently, I understand the color of it is not for everyone but personally I dig it and it’s not painted it’s molded in the color so you won’t have to worry about it rubbing off, if you are interested I’d say definitely give it a go, this is perfect for a beginner or intermediate player or even just for a collection like myself, I give it a 5/5 stars for what it is

Solid body
Solid gearbox
Great looks IMO
High fps

Front wired to handguard
No rails other than on top of the receiver

Overall I think it’s a great gun especially for the price, CYMA is a well known brand that has a great track record and honestly I don’t think you can go wrong buying this gun
