Hello guys, so I just picked up a used NT11 for about 300$.
It didn't come with a case or any spare parts, just the marker and the barrel.
So far I figured out that I need the Red, yellow and green bolt spacers. And the Red, blue and green bolt flow tips.
My question is, I've read somewhere that I need to have a black rubber thing on the top of the bolt (on the flow thing), is that true?
I'll add a photo of my bolt so that you guys can see what it looks like now.
EDIT: So the basic question is, what am I missing? (Dont care about the lube, multitool and so on)
