So I bought my mk18 with a black RISII, I put in an fde version. But I didn't change the "bolt up plate"(as DD calls it). I don't know what that's called. And now I want to sell the black RISII I have laying around. But I need to switch that rail bolt up plate to the FDE. I just don't have know how to remove the barrel nut or barrel. Need to have that taken off and put on the FDE rail bolt up plate.
I'll take a photo because I'm horrible at explaining this.
So I need to switch that plate there. I've looked up how to do it, pop the pin off the gas block and stuff, but I'm just not that confident in doing that stuff. I don't want to screw anything up.
Unles it's actually really easy. Then I could probably do it.
