M&P AR15 high or low shelf?

[lfurr]

Should have just asked if the SS was compatible with the M&P AR15.

Is it?

Is it?

Maybe.

The SS works easiest with low shelf. High shelf just means a little material needs to be removed from behind the selector. Can be done with Dremel, where the broken parts are yellow pointer, behind the selector in the pic.

Needs:
Full auto carrier
H3 buffer
Mil spec trigger and hammer

Low-shelf meaning, the height of the aluminum material behind the selector cam is lower than the top of the selector cam.

High-shelf meaning, the height of the aluminum material behind the selector cam is even to the top of the selector cam.

I learn something here nearly every day.

I still recommend people fit there own triggers. Many SS makers still over round the triggers. People should only round the left side of their trigger just enough to barely fit the SS cam. Don't use the 3D printed jigs.
