Hope I got the right forum - also I did not notice upon searching....

To support Magpul, I added their MIAD grip to my M&P15A.
There is just a tiny bit of play in it forwards/backwards.
The flathead screw is definitely tight.
I'm wondering if it is bottoming out on the lower or ????

Saw a little online about this. Some say add a washer (magpul does not because of storage space) - some say use the OEM screw (mine is starting to strip).
I ordered a MAKO to see if this would be any different plus some new hardware.

Other thoughts? Anyone else have this?
