My KWA KRISS - Undergoing project

So, im still im the project fase, tried a few things out, saw others, and have a good idea where i am going and wanna go.
So far this is what i got to show for:



(lousy pic i know, cell phone camera...)

Im a while ill have some goodies to add to it, so far i added the paintjob in SAND (the yellow is mandatory by law here, i got a front barrel adapter with 10cm in yellow for transport too), added some rail covers in TAN, silencer, and added 2 magpull RSA sling mounts, since im running a 3 point sling to it, the reflex sight is gonna go, too low for me and in the rain u dont see the dot.
The goodies ill be adding soon, and will post pics when i get it, its an Eotech EPX (unsure of the correct model number), an AFG (yup gonna mod it), laser and flashlight (the G&P T1 Cree led), also an internal goodie, the recoil spring kit.
Would love to add either a right side lever or left extended lever to improve the mag change also, who knows, one can buy in the near future or machine one...

Pretty nice! I was going to ask about the yellow, I kind of figured there was a reason for it.

so just the stock has to be yellow

Actually no! The front barrel in this case as to have 10 cm also painted yellow but we can change/hide in games, so the pic is of it as i use in game.
If i come across a store selling the stock for it, i will buy and simples change that for this one out at the end of games for transport and having it stored at home. But since its brand new parts and acessories are scarse for now on the stores i know, only this week ill be getting more mags for it...

Heres what i mean:



That yellow tip? Simply unscrew and get the silencer on.

Is the yellow stock painted yellow? Or casted in yellow plastic?

Its painted.
