Securing MC/AC cable to existing outlet box
 
Standard 4" Steel Box in Wall.
I suppose a good wack of a flathead screw will be able to get a knockout out.

I plan to run a new line to this box if doable...

Do they make special fittings that I can use to secure a BX cable in a 1/2 knockout or 3/4 ........that I can secure to the box IF I only have access to the *inside* of the box ?

Put the connector on before fishing it down the wall.

Otherwise, they make snap in connectors for MC that don't use a locknut.

Put a connector onto the flex before you fish it to the box. Then have the nut handy to screw onto the connector. ???

Genius - on putting the connector on the cable before fishing it ! I did not even think about doing it this way...

Any secret sauce advice on knocking out the knockout from the inside of the box.

It's a tile backsplash so I want to keep vibration to a minimum...

Flat head screwdriver.
Push on tab to bend it,once it bends rock it back and forth till it snaps off.
