Another great magpul product - Magpul MLOK Hand Guard Rail Section

I'll start by saying not all mlok accessories are created equal, and a poor fit can actually damage your rail and possibly eventually fall off. I trust these guys, still haven't tried the aluminum, but the three slot version is perfect for mounting a tripod or small light, I find that I rarely need any more length than that, the rounded edges are a bonus too, very comfortable to grab even without a rail cover, they are my go to rails.
