mohave - Thank you for your service.

The arm brace was mentioned by the AG in a press conference about 2 months ago. So they certainly have it in their sights.

But I suggest you keep your pistol, keep all your firearms, and buy more ammo.

At this point and time in history, I think any future federal bans will be met with mass non-compliance. Case in point, the 2013 high capacity mag State ban in CT resulted in about 30% compliance (that may be higher now, don't know). And that's CT. Think how compliance will go in the more conservative states. People are not going to be laying down their weapons, or even gun parts. The general gun owning population are sick and tired of the "slippery slope" tactics used by the anti-gun crowd.
