I would normally use an AR-15 upper receiver block, but I have a GBBR so I'm not quite sure how closely the inner of AEG uppers follow the RS spec. Brownells has upper receiver clamps which rely on the outside of the receiver instead of the inside. Clamp the receiver into it, put the gun in the vice, work slowly. You can wail on an RS receiver, but on a pot metal AEG receiver I'd err on the side of caution and use heat on the nut if required. If you really don't feel like the investment, you can make your own blocks... but ensure you're accurate and on point. Having a loose vise block is an entire level of frustration.
Don't ever do it with your receivers linked, ever. Even on a real AR the pivot pin points aren't meant to take that moment/torque (Note the reinforcement from A1 to A2 receivers) and on an AEG, you WILL snap the pivot points.

I already feel dicey doing it with an actual AR-15 upper receiver, though I suspect it's more due to the fact that aluminum is much lighter than pot metal despite its higher strength.
