Print:

The only supports needed are at the bottom of the the grip and the counterbore areas near the top. The ceiling of the hand stop is conical so it will print fine with overhang. Use the Smart fill option of the paint on supports setting, and use organic supports.

Once printed, remove supports and then install using the standard M-LOK installation procedure. 

If printing in resin, use auto supports and add extra supports around the hole in the counterbore and use an offset from the build plate at least 5mm.
