I'm looking at doing an order from EBAirsoft for my broke-ass GR16, however I just want to check some things before I do.
I'm looking at getting
5 Magpul PTS PMAGs(not the version with the mag level window)
DBoys 7mm Gearbox
Troy folding sight(rear)
JG Charging handle
Am I going to have to worry about the magazines clearing customs? Better yet, what kind of compatibility issues am I going to have with these parts?
Sorry for sounding like a noob.
