Great mount, requires work for mounting a streamlight - Midwest Industries Raise Straight Surefire Light Mount, M-Lok

The light mount itself is sturdy and low-profile, I have two. However, there is a mild incompatibility with Streamlight. I mounted a Streamlight ProTac HL-X on each, and though the hole pattern for the mounting screws are the same as on Surefire weapon lights, the tailcap end of the Streamlight obstructs access to one of the M-lok screws when the light is mated to the light mount. Probably works fine for mounting Surefire lights, though.

I was able to work around this by cutting the short end of an appropriately sized allen key down so that it can access that screw, but someone without access to the necessary tools or who doesn't want to sacrifice an allen key should use the offset light mount for their setup.
