Good non flapdown M4 AEG grips?

[pyromancer6]

As stated in the title - looking for suggestions on some decent screwed-baseplate M4 AEG grips as my flapdown/hinge retention ones let me down again and dropped the motor, ideally not A2 shaped as it doesn't fit the style of rifle.

Something like this which uses a hinge mechanism which in my experience had led to unreliability with the motor height, seeing as it keeps dropping and screeching the gears

I mean there's dozens of styles out there, what's it going on? I can say the PTS EPG is well made, screw in base plate, just as one example.
