Customizing Your Gun?

I've heard something about being able to customize your gun (Different Ext I think?) in Thai Point Blank. Well heres the video.

You'll notice that this P90 MC has..
- 30 Bullets NOT 50
- Holographic Sight NOT RDS
- A silencer
- A grip
- RIS Rail NOT TRIPLE RAIL
If you look at the comments below one guy says
"Pretty Nice video! =D

Anyway, there's a way of customizing your gun in TH PB?

PB in Brasil is a bit new...they are starting to release cool weapons right now =)

And yeah, BS is cool =)"
CUSTIMIZATION!?!?!
