'Dboys' M4 S-System AEG (BI3381 - metal)

It's an ok gun for a start. It was my first rifle.
First things first: Some parts needed tightening, like the iron sights, stock and RIS system. The vertical grip that followed defected after a couple of times in play, it wouldn't stick to the RIS anymore, so it just fell off. Minor design error on the part between the front iron sight and the RIS. You can see the shiny metal there, it's not supposed to be like that.
Manufacturer says this gun is 350fps. Mine chroned to 280fps. Even after switching spring and hop-up, it was only 290. Might have come with a damaged piston or such.
The 8.4v battery that comes with it gives it the worst RoF ever. Should consider getting a 9.6v at the same time as getting this one.

But, apart from all this, it's a really cool looking rifle, and it can become sturdy and accurate, you'll just need to spit in a few extra dollars.

Nice AEG, perfectible as well, some modification needed to be the perfect weapon on the battlefield ! Only his heavy body make you tired :P but very powerfull as well.

Make it yours, you will not regret it !

beautiful rifle...rails not very line up, problems to the trigger (perhaps only in my case)...but solid and strong..precise..fast and reactive gust to the pressure on the trigger!!! Very good battery...possibility to climb on a silencer!!!

Absolutely to buy..totally in metal, also hop-up!!!
